The control system receives the measurements to maintain a programmed lighting output in both dimmed and switched lighting systems.The Paradigm Light Sensors are available in three models:•P-LS - Light Sensor with Controller •P-LSC - Light Sensor Controller Only •P-LSH - Light Sensor Only Each controller supports an individual pair of Light Sensors and is available in neutral white or black finish.A light sensor may be installed within the controller or installed remotely, using up to 1,000 feet (304m) of 16 AWG wire per controller. When using a pair of light sensors, both sensors transmit their light readings to a single controller which provides an averaged reading to the connected Paradigm control system.Wire SpecificationControllerThe Paradigm Light Sensor utilizes LinkConnect to power the sensor and to provide data to and from the connected Paradigm control system.LinkConnect is topology-free and polarity independent. You can install your data runs in any desired combination of bus, star, loop, and home-run. ETC recommends using Belden 8471 (or equivalent) wire. The total combined length of a LinkConnect wire run may not exceed 1,640 feet (500m), with a maximum distance of 1,312 feet (400m)between any two devices.light sensor with controllerlight sensorthread extenderAll control wiring should be installed and terminated by a qualified installer, should follow standard wiring installation practices, and meet local codes. Leaveapproximately 10 inches (254mm) of wiring in the junction box or tied back in the ceiling to allow for wiring connections and future service needs.Remoting the Light SensorThe Paradigm Light Sensor Controller provides termination for up to two light sensors. Each light sensor must be separately wired to the controller using no more than 1000 feet (304m) of 16 AWG wire total per controller. These wire runs must remain separate from LinkConnect wiring. ETC recommends using Belden 8471 (or equivalent) wire.Installation EnvironmentThe Paradigm Light Sensor Controller is intended for installation to a finished ceiling surface, soft ceiling tile, attached to a round fixture junction box or single-gang RACO switch box. The controller operates in ambient temperatures of 0°C to 40°C, non-condensing humidity.The Paradigm Light Sensor can be mounted directly in the controller , installed to a 1/2” conduit knockout or installed into a soft ceiling tile using the provided light sensor thread extender. The light sensor can be installed outdoors when mounted to a weatherproof enclosure. The sensor in this weatherproof installation scenario operates in ambient temperatures of -25°C to 70°C.Parts and SuppliesThe following parts and supplies are included with the specific Paradigm Light Sensor assembly ordered:N o t e :ETC requires that all stations be grounded by using a 14 AWG (2.5mm 2) ESD drain wire.Parts and Supplies Light Sensor complete unit (P-LS)Light Sensor only (P-LSH)Light Sensor Controlleronly (P-LSC)soft ceiling tile adaptorX X LinkConnect and ground wire pigtailsX X light sensor thread extenderX X 3 position WAGO connectorsX X 2 position WAGO connectorsX 1 each nuts and washers 3/4” and 1”X X 2 each screws 6-32 x 3/4” and 1 3/4”X X blank sensor head X XInstallationThe Paradigm Light Sensor is provided with a twist-lock mounting plate that can be mounted to a finished ceiling, junction box, or soft ceiling tile.

Power Up and TestPower UpFor power to be applied to the Paradigm Light Sensor, any additional LinkConnect terminations for the system must also be made. In addition, the ParadigmArchitectural Control Processor (P-ACP) and Station Power Module (P-SPM) must be installed in the host DRd or ERn rack enclosure.Identify Number of Connected Remote SensorsThe controller termination board includes an LED, labeled ‘Sensor Count’ that blinks according to the number of remote sensors installed. As needed, refer to this LED to ensure the system has been wired properly and the controller has properly detected the correct number of connected light sensors.Binding Sensors to ParadigmThe Paradigm Architectural Control Processor (P-ACP) to which this sensor is physically wired to must learn, or be told, the station hardware address (known as a neuron ID). When the sensor is unbound from the connected P-ACP, the service pin LED blinks.The neuron ID is labeled on the sensor control board and can be manually entered into the configuration using LightDesigner software. Alternatively, the sensor can be identified using the service pin button (designated with “S” on the button) and by the connected Paradigm ACP using its [LonWorks Connections] menu. Reference the related source documentation, either the LightDesigner Online Help System or the Unison Paradigm Architectural Control Processor Configuration Manual; specifically the section on Arch Setup Menu, LonWorks Connections.Record a Target Lighting ValueThe Paradigm Light Sensor includes a button that by default provides recording of target lighting values for its dimming daylight harvesting feature. Pressing the record button enables a five second timer and illuminates the LED red. When the timer expires, the measured light level is stored as the amount of desired light that the connected Paradigm control system should maintain, and the red LED blinks twice to confirm.。

Doing so could lead to serious injury or death. This device does not include the self-checking redundant circuitry necessary to allow its use in personnel safety applications. A sensor failure or malfunction can cause either an energized or de-energized sensor output condition.ModelsOverviewThe PVD Series Parts Verification Sensor is a one-component, easy-to-use light screen suited to many part assembly, bin picking (pick-to-light), and error-proofing applications. The PVD increases task efficiency due to simplified job training, increased quality control (no skipped components), and reduced rework and inspections. It speeds the resumption of work after breaks and other distractions, and is ideal for multilingual workplaces where communication is an issue.The PVD self-contained, solid-state emitter/receiver array is capable of functioning in either diffuse or retroreflective sensing mode. Noconfiguration is required for this selection. If a retroreflective target is installed opposite the sensor, it will function in retroreflective mode. If not, it will function in diffuse mode. The sensor’s ongoing self-adjustment feature requires no user adjustment; the sensor adapts to the sensing conditions after 15 seconds when blocked. Sensor range decreases when no retroreflector is installed.The DIP-switch-selectable PNP/NPN output interfaces to a system controller, which is pre-programmed for a specific sequence of tasks.Mounted with its visible red beams stretching across each parts bin, the sensor job light signals the assembler which bins contain items to be picked in a given operation and in what order they should be picked.As the assembler takes a part in sequence and breaks the beam, the sensor senses that the part was removed and it sends an output signal to the controller. The controller then verifies if the correct part was taken and may respond by turning that job light OFF, activating the job light of the next bin in the sequence. If the assembler reaches into a bin out of sequence, the PVD turns on its output to signal the system controller and turns on its red job light to signal the assembler that an incorrect pick has occurred.Standard configuration options are selected by means of a bank of four DIP switches behind a press-on black rubber cover. DIP switch options include: PNP or NPN output, Normally Open or Normally Closed operation, steady or flashing job light, and job light control input.•To order the 150 mm (6 in) cable model with a quick disconnect, add the suffix "W/6IN" to the cabled model number. For example,PVD100Q W/6IN.•Models with a quick disconnect require a mating cordset.PVD Series Parts Verification SensorOriginal Document 113230 Rev. G4 August 2016113230Figure 1.

Minimum object detection size (retroreflective operation)InstallationMultiple sensors located farther than the sensor's maximum range from one another are unlikely to cause crosstalk problems. However, when multiple sensors are mounted in a confined area, take care to avoid crosstalk between them. Alternate the relative position of adjacent sensors and/or reflectors. Sensors positioned above or below one another should not create crosstalk difficulties. Mount the sensor and reflector parallel.Figure 3. Examples of Appropriate Positions Figure 4. Example of Incorrect Position - Tel: +1-763-544-3164P/N 113230 Rev. GMountingThe wide beam pattern of PVD sensors simplifies their alignment. M4 stainless steel fasteners and two stainless steel brackets are included with each sensor.Mount the sensor and its reflector, if used, parallel to one another in the same plane, and their tops and bottoms aligned.1.From a common point of reference, make measurements to locate the sensor and itsreflector, if used, in the same plane with their midpoints directly opposite each other.2.Mount the included brackets to the top and bottom of each sensor, as shown.3.Mount the sensor in its brackets and the reflector, if used, being careful to position thesensor's red lenses directly facing the reflector.4.Measure from one or more reference planes (for example, the building or bin floor) to thesame point(s) on the emitter and receiver to verify their mechanical alignment. (If the sensors/reflectors are mounted exactly vertical or horizontal, a carpenter’s level may be helpful. A straightedge or a string extended between the sensor and the bin wall may also be helpful.)5.Also check “by eye” for line-of-sight alignment.6.Make any necessary final mechanical adjustments, and hand-tighten the bracket hardware.7.After the electrical hookup is complete, check for beam alignment. If necessary, re-align theemitter and receiver at that time.Figure 5. PVD MountingHardwareWiringAll models feature integral 2 m (6.5 ft) long, 3.3 mm (0.13 inch) diameter PVC-jacketed cables. Models whose model numbers end in “Q”are terminated with quick-disconnect (QD) Euro-style 5-pin connectors; other models have unterminated ends. Optional mating QD cables are available. Either 4-pin or 5-pin QD cables may be used; the center pin of a 5-pin cable (gray wire, pin 5) is unused in normal operation.Wiring is functionally identical for cabled and quick-disconnect models.NPN (Sinking) OutputPNP (Sourcing) OutputKey–+–+1 = Brown2 = White3 = Blue4 = Black5 = GraySee Configuration on page 3 for job light control input requirements.ConfigurationTo configure the PVD, set the DIP switches as shown, using the supplied plastic screwdriver to avoid damaging the switches or causing a short circuit.P/N 113230 Rev.

A device failure or malfunction can cause either an energized (on) or de-energized (off) output condition.OverviewBanner MAXI-BEAM ® sensors are highly versatile, self-contained, modularized photoelectric sensing controls that are ideally suited to industrial environments. The basic MAXI-BEAM is an ON/OFF switch consisting of three modules (sensor head,power block, and wiring base) and a unique, patented, rotatable programming ring that enables you to program your choice of light or dark operate mode, sensing range, and response time.MAXI-BEAM sensor heads have an easily-accessible multi-turn sensitivity control for precise adjustment of system gain. Interchangeable sensor heads are rotatable in 90-degree increments and are available in retroreflective, diffuse, opposed,convergent, fixed-field proximity, and fiberoptic sensing modes. Each sensor head also includes Banner's exclusive, patented AID ™ circuit (Alignment Indicating Device, US Patent no. 4356393), which features an LED alignment indicator that lights whenever the sensor sees its own modulated light source, and pulses at a rate proportional to the strength of the received light signal.A wide selection of MAXI-BEAM power block modules is available to interface the sensor head to the circuit to be controlled. The plug-in design of the wiring base enables easy exchange of the entire sensing electronics without disturbing field wiring.Optional customer-installable logic modules easily convert the basic ON/OFF MAXI-BEAM into either a one-shot or delay logic function control, with several programmable timing ranges for each function.MAXI-BEAM sensors are ruggedly constructed of molded PBT to NEMA standards 1, 3, 4, 12, and 13, and have interchangeable molded acrylic lenses. Modulessimply snap and bolt together, with no interwiring necessary. Module interfaces areo-ring and quad-ring sealed for the ultimate in dust, dirt, and moisture resistance.Rotatable Sensor Head Programming RingLogic Module (optional)Programming Ring for LogicRWB4Wiring Base Power Block Conduit EnteranceMAXI-BEAM Opposed Mode Emitter (E) and Receiver (R)MAXI-BEAM emitters have a visible red "tracer beam". This beam is non-active, and is used as a means of visual alignment during installation. A retroreflector temporarily attached to the receiver lens provides aneffective target for the tracer beam during alignment. The narrow beam of the RSBESR/RSBRSR pair is ideal for sensing small parts (effective beam diameter is 3.6 mm (0.14 in).One emitter and one receiver are required for use.MAXI-BEAM ® Sensor HeadsOriginal Document 03416 Rev.

光敏电阻光照传感器引脚说明

光敏电阻光照传感器引脚说明

光敏电阻光照传感器引脚说明光敏电阻(Light Dependent Resistor, LDR)是一种基于光电效应原理的光照传感器,它能够根据周围环境的光照水平来改变自身的电阻值。

光敏电阻的工作原理是通过光的照射,使得材料中的光敏介质导电性发生变化,从而改变电阻值。

光敏电阻在许多电子设备和应用中广泛使用,例如光照控制、光敏报警、光敏开关等。

在光敏电阻中,引脚的设计和安装方式非常重要,它们直接影响了光敏电阻的性能和使用效果。

一般来说,光敏电阻通常包含两个引脚,其中一个是正极引脚(也称作AN脚),另一个是负极引脚(也称作GND脚)。

正极引脚通常连接到正电源或电流采集电路,负极引脚连接到地或负电源。

在使用光敏电阻时,我们通常需要将其连接到一个合适的电路上,以便实现对光照变化的检测和响应。

常见的连接方式有两种:串联和并联。

串联连接方式是将光敏电阻的正负极依次连接到其他元件或电路中。

这种连接方式适用于需要根据光照变化来改变电路中其他元件的工作状态或电流的应用。

在光照控制系统中,我们可以将光敏电阻串联连接到一个可变电阻或电路中,当光照变强时,光敏电阻的电阻值降低,从而导致整个电路中的电流增大,最终控制灯光的亮度。

可以选择并联连接方式,将光敏电阻与其他电阻或电路并联连接。

这种连接方式适用于需要将光敏电阻与其他元件共同构成电压分压器或电流分流器的应用。

在光敏报警系统中,我们可以将光敏电阻并联连接到一个电压比较器电路中,当光照强度达到一定阈值时,光敏电阻的电阻值变化会导致电压比较器输出高电平,从而触发报警装置。

在使用光敏电阻时,我们还需要注意一些性能参数,例如灵敏度和响应时间。

灵敏度是指光敏电阻对光照变化的敏感程度,一般用引脚的电阻值来表示。

较低的电阻值意味着光敏电阻对光照的变化更为敏感。

响应时间是指光敏电阻从受到光照变化到输出信号变化所需的时间。

较短的响应时间可以更快地检测到光照的变化。

光敏电阻作为一种光照传感器,在电子设备和应用中起到了至关重要的作用。

光敏传感器使用手册

光敏传感器使用手册

光敏传感器使⽤⼿册光敏传感器使⽤教程光电⼆极管(也称光敏⼆极管)是将光信号变成电信号的半导体器件, 是在反向电压作⽤之下⼯作的。

它的核⼼部分也是⼀个PN结,和普通⼆极管相⽐+,在结构上不同的是,为了便于接受⼊射光照,PN结⾯积尽量做的⼤⼀些,电极⾯积尽量⼩些,⽽且PN结的结深很浅,⼀般⼩于1微⽶。

光电⼆极管没有光照时,反向电流很⼩(⼀般⼩于0.1微安),称为暗电流。

当有光照时,携带能量的光⼦进⼊PN结后,把能量传给共价键上的束缚电⼦,使部分电⼦挣脱共价键,从⽽产⽣电⼦---空⽳对,称为光⽣载流⼦。

它们在反向电压作⽤下参加漂移运动,使反向电流明显变⼤,光的强度越⼤,反向电流也越⼤。

这种特性称为“光电导”。

光电⼆极管在⼀般照度的光线照射下,所产⽣的电流叫光电流。

如果在外电路上接上负载,负载上就获得了电信号,⽽且这个电信号随着光的变化⽽相应变化。

光敏⼆极管特性曲线光电流---正电压特性短路电流---照度特性波长分布特性光敏⼆极管的特点:1、应⽤时反向偏置连接;2、没光照射,呈现极⾼阻值;3、有光照射时,电阻减⼩;4、可作光控关关光敏⼆极管的符号及接线图光敏⼆极管符号光敏⼆极管接线图光电⼆极管与光电三极管的联系与区别光电⼆极管、光电三极管是电⼦电路中⼴泛采⽤的光敏器件。

光电⼆极管和普通⼆极管⼀样具有⼀个PN结,不同之处是在光电⼆极管的外壳上有⼀个透明的窗⼝以接收光线照射,实现光电转换,在电路图中⽂字符号⼀般为VD。

光电三极管除具有光电转换的功能外,还具有放⼤功能,在电路图中⽂字符号⼀般为VT。

光电三极管因输⼊信号为光信号,所以通常只有集电极和发射极两个引脚线。

光敏传感器的用法 -回复

光敏传感器的用法-回复光敏传感器是一种能够检测光线强度的电子设备。

它基于光敏材料的光电效应工作原理,能够将光转化为电信号。

光敏传感器在各个领域广泛应用,例如照相机、光度计、光电测距仪等等。

本文将从光敏传感器的原理、结构和工作方式,以及其在不同领域的用途等方面进行详细介绍。

一、光敏传感器的工作原理光敏传感器的工作原理基于光电效应,即光照射到光敏材料时会产生电信号。

光敏材料通常是一种半导体材料,例如硅、碲化镉(CdTe)、硒化铟(InSe)等等。

这些材料的能带结构使得它们可以吸收入射光的能量,从而产生光电导致电子的迁移和电流的流动。

当光照射到光敏材料时,光能量激发了光敏材料中的电子,使其从价带跃迁至导带。

跃迁后的电子在导带中运动,从而形成电流。

光敏传感器会测量这个电流的强度,进而获得光线的强度。

二、光敏传感器的结构和工作方式光敏传感器通常由光敏元件和电子电路组成。

光敏元件是光敏材料制成的一小块晶体或薄膜,用于感受光线。

电子电路则是将光敏元件产生的电信号进行放大和处理的部分。

光敏传感器有多种不同的结构和类型。

最常见的类型是光敏二极管和光敏电阻。

光敏二极管由光敏材料制成的二极管,光照射到二极管时,电流的变化将被测量。

光敏电阻则是一种电阻器,光照射到电阻上会改变其电阻值,进而导致电流的变化。

光敏传感器的工作方式可以分为两种:间接检测和直接检测。

间接检测是通过测量光源照射在被测物体上的光强度变化来推断光源的亮度。

而直接检测则是直接测量光源的亮度。

三、光敏传感器的应用领域1. 照相机:光敏传感器是数码相机的核心组件之一。

它用于将光线转化为图像信号,通过后续的图像处理技术生成成像。

2. 光度计:光敏传感器可以测量光的强度,从而实现对环境光照的测量。

这在照明工程、智能家居和室内环境监测等领域非常重要。

3. 光电测距仪:光敏传感器可以用于测量物体与传感器之间的距离。

这在机器人导航、自动驾驶和物体识别等应用中起着关键作用。
