GF4C旋转限位开关（黄盒子）

1、概述

The rotary limit switch is used to control the movement of industrial machinery. It operates 旋转限位开关被用来控制工业机械的运转，

as an auxiliary controller of electrical motors through a power interface, such as a contactor or

通过电源接口连接作为电动机的一个辅助控制器，好比一个开关或者PLC。

PLC . Suitable for heavy duty, its shaft is connected to the motor and, after a set number of revolutions ,the cams operate the switches, thus starting the predetermined movement . A worm 适用于重载，它的轴连接到电机，并且通过设置转数控制开关，实现预设的操作。一个涡轮gear and a helical toothed gear combined with one or more pairs of straight toothed gears are used for the transmission of the movement from the input shaft to the output shaft.

和一个螺旋形的齿轮连接一个或者多个直齿，用作主动轴和从动轴间动作的传动装置。

Revolution ratios, ranging from 1:1 to 1:969, result from the use of different combinations of gear wheels between the input shaft and the output shaft, which is connected to the cams operating the switches. Transmission and gear driving shafts are made of stainless steel to 按照主动轴和从动轴之间，连接到凸轮控制的开光的齿轮啮合程度的不同，转速比范围从1:1到1:969。传动轴和齿轮轴由不锈钢构成，防止氧化和磨损。

prevent oxidation and wear. The gear wheels and the driving bushes are made of self-lubricating thermoplastic material, suitably chosen to reduce the wear to a minimum and to maintain the accuracy of the couplings over time. Sintered bronze bushes are moulded into the base of the 齿轮和驱动轴由具备自身润滑的热塑材料制成，可以减轻轴的磨损和保持精密性。

limit switch to optimise the shaft rotation and to prevent rubbing with plastic material.

烧结青铜被浇铸作为限位开关的基部，使轴旋转最优化，并防止和热塑材料的摩擦。

Each cam can be set with great accuracy thanks to the cam adjusting screws. The auxiliary 由于凸轮调验螺丝，每个凸轮都能被精确的设置。

switches are of a positive opening type, thus suitable for safety functions. It is available with direct control switches for operating directly on the motor.

每个开关都是正面开放的，适合于安全功能。它通过直接控制开关来控制电机运转。

The cam-switch sets can be substituted for potentiometers suitable for the connection to

electronic equipment. Each output of the limit switch can be set with a different revolution ratio to allow for a diversified control of the machinery to meet special requirements.

凸轮开关设置能够替代电位计来连接电子设备。每个限位开关都能够设置不同的转速比，实现机械装置的多元化控制以满足不同的特殊要求。

Materials and components are wear resistant and protect the equipment against water and dust. The limit switch is available with a flange for direct coupling to the motor and it can be customised with labels and colours according to the customer’s requirem ents.

设备材料和部件具备耐磨性，并且保护设备防水、防尘。限位开关通过一个法兰直接连接电机，并且可以依据客户要求配置不同的颜色和标签。
