3121中文资料

These Hall-effect switches are monolithic integrated circuits with tighter magnetic specifications, designed to operate continuously over extended temperatures to +150°C, and are more stable with both tem-perature and supply voltage changes. The unipolar switching character-istic makes these devices ideal for use with a simple bar or rod magnet.The three basic devices (3121, 3122, and 3123) are identical except for magnetic switch points.Each device includes a voltage regulator for operation with supply voltages of 4.5 voltas to 24 volts, reverse battery protection diode,quadratic Hall-voltage generator, temperature compensation circuitry,small-signal amplifier, Schmitt trigger, and an open-collector output to sink up to 25 mA. With suitable output pull up, they can be used with bipolar or CMOS logic circuits. The 3121 is an improved replacement for the 3113 and 3119.The first character of the part number suffix determines the device operating temperature range. Suffix ‘E–’ is for the automotive and industrial temperature range of -40°C to +85°C. Suffix ‘L–’ is for the automotive and military temperature range of -40°C to +150°C. Three package styles provide a magnetically optimized package for mostapplications. Suffix ‘–LT’ is a miniature SOT-89/TO-243AA transistor package for surface-mount applications; suffix ‘–U’ is a three-lead plastic mini-SIP while suffix ‘–UA’ is a three-lead ultra-mini-SIP.HALL-EFFECT SWITCHESFOR HIGH-TEMPERATURE OPERATIONAlways order by complete part number, e.g., A3121EU .FEATURES and BENEFITSI Superior Temp.

When the magnetic field is reduced to below the release point threshold (B RP ), the device output goes high. The difference in the magnetic operate and release points is called the hysteresis (B hys ) of the device. This built-in hysteresis allows clean switching of the output even in the presence of external mechani-cal vibration and electrical noise.APPLICATIONS INFORMATIONHall effect applications information is available in the “Hall-Effect IC Applications Guide”, which can be found in the latest issue of Allegro MicroSystems Data Book AMS-702.CHANGE IN OPERATE POINT10152025SUPPLY VOLTAGE IN VOLTSDwg.

Trapezoidal-Connectors Series TMCGeneralSeries TMC connectors are available in 5 different housing sizes with 9, 15, 25, 37 and 50 pins. In applications these connectors are frequently used for interface connections.Owing to the various sizes of housing series TMC connectors match virtually any application.Wires can be connected by manual soldering, insulation displacement and crimping. For use on PC boards there are versions with straight or angled pins for machine soldering. For versions with straight pins there is also the solderless press-fit technique (ERNIPRESS).You can find ordering details for connectors with crimp terminiation and ERNIPRESS on separate data sheets.AccessoriesFor series TMC connectors ERNI has a wide range of acces-sories available.No matter whether the important criterion is easy assembly, different types of mounting, electromagnetic compatibility, locking devices or connector housings, you will find attractive solutions at ERNI.Main features•Indirect mating system•International approval certificates such as UL and CSA • 5 housing sizes with 9, 15, 25, 37 and 50 pins •Accessories integrated into the connector•Tinned metal housing•Laminated ground contact on the male housings for optimal screening• 3 different connector housing types available•Various types of termination available•Solid contacts on the male connectors with tinned manual soldering terminationSubminiature-D Connectors to DIN 41 652/IEC 807-3D-Sub TerminationPerformance Levels207to DIN 41 652/IEC 807-3MIL-C-24308, CCTU 08-14and IEC-Recommendation 48 B200 mating cyclesContact zone gold-platedterminal zone tinned201as for version 207 butterminal zone gold-plated 107to DIN 41 652/IEC 807-3MIL-C-24308, CCTU 08-14and IEC-Recommendation 48 B500 mating cyclesContact zone gold-platedterminal zone tinned101as for version 107 butterminal zone gold-platedPerformance level 107and101connectors are available on request.Approval CertificatesUL All male and female connectors from this data sheet are approved by the American certification authority …Under-writers Laboratories Inc.“.File no. E 84703CSA All types are listed by the Canadian certification author-ity …Canadian Standards Association“.File Nr. LR 62503 and LR 62504.For ERNIPRESS, crimping and insulation displacement (IDC)there are separate data sheets available.Integrated AccessoriesRiveted nut (see fig. 1)On the version with riveted nut there is a nut riveted into the mounting flanges of the connector so that it cannot twist. The thread is available as a M3 and 4/40" version. This facilitates fitting into housings or front panels.Threaded bolt (see fig. 2)To ensure secure connector locking, a screw locking device is frequently used with threaded bolts. TMC connectors from ERNI are available with riveted threaded bolts. These hexagon bolts are available with internal threads of M3 and 4/40". For the user it means there is no need for loose accessories.Spacer bolt (see fig. 3)Due to the design of the TMC connectors a spacer is required for vertical assembly on pc boards. These parts are supplied by ERNI as individual accessories.Ground pin (see fig. 4)The additional ground pin is designed for connecting up to the pc board chassis contact for example.Spacer bolt with mounting clip (on request)(see fig. 5)These spacer bolts can be snapped into the mounting holes on the pc board. If the holes are plated-through there will also be a solder joint.Ground clip (see fig. 6)For screening contact there are angled ERNI TMC connector ground clips available. These clips are soldered into the mounting holes on the pc board, thus creating a firm chassis connection.Ground bar (see fig. 7)Ground bars on angled connectors are attached to the guide frame on the pc board. This makes it possible to make connection with chassis conductors on the pc board.Ground eyelet (on request) (see fig. 8)With the ground lug the chassis contact can be soldered on.D-Sub Tinned metal housings andlaminated ground contactsThe metal housings on the TMC connectors (standardversions) from ERNI are tinned so as to achieve better contactfor the chassis connection. Specially punched grooves on themetal protective collar of the male connectors ensure reliable contact. Together with the ERNI connector housings in the metallized version and grounding accessories on the connec-tors an optimal electromagnetically compatible application is achieved.Solid punched male contactsDue to a special manufacturing process we are in a positionto offer solid punched male contacts.These versions have a tinned terminal zone and are suitablefor a current-carrying capacity of up to 7.5 A.Guide frame for angled connectorsFor mounting purposes and better guidance of angled TMC connectors with pins for dip-soldering the standard versionsare equipped with a guide frame made of plastic.With this guide frame the connectors can be screwed orriveted onto pc boards.Versions with a guide frame and mounting clip are clipped intothe pc boards and soldered in place.Connector housings for TMC connectorsERNI has also developed connector housings for series TMC interface connectors.• KSG 183housing with engagement locking• KSG 184housing with slide locking• KSG 185housing with engagement and/or screwlocking, integrated codingThese two-shell connector housings are also available inmetallized versions.

USP33-1231制药用水__中文译稿

USP33-制药用水<1231>制药用水<1231>引言在药品、原料药和中间体,药典产品以及分析试剂的加工、制备和生产过程中,水被广泛用作一原料,组分和溶剂。

此通用章节的信息提供了有关水的其它信息:未被包括在的水的专论中的属性,可以用以提高水质量的处理技术,以及在选择水源时应考虑最低水质量标准的描述。

此信息章节并未打算替代现有的条例或指导,现有的这些条例或指导涉及USA和国际的(ICH或WHO)的GMP问题,工程指导或其它关于水的条例(FDA、EPA或WHO)指导。

其内容有有助于使用者更好地理解制药用水问题以及一些仅针对水的微生物和化学问题。

此章节并不是关于制药用水的一个全面综合性的文件。

它包括在水的处理、贮存和使用时需要考虑的基本信息点。

保证制药用水以及生产符合相适用的政府条例、指南和各种类型的水的药典标准是使用者的职责。

这些水的化学纯度的控制是很重要的,并且是本药典中各论的主要目的。

与其它药典产品不同,大批量水专论(纯化水和注射用水)也限制此产品是如何被生产的,因为认为纯化过程的本质与完善程度与(水)最终的纯度直接相关。

在这些个论中所列的化学属性应被看作为一组最低的规范要求。

对于某些应用来说,可能需要更加严格的规范以保证适合其特定的用途。

关于这些水的适当应用的基本指导可以在正文中找到,并且在本章节中给出更进一步的解释。

对于很多水的用途来说,控制其微生物质量是很重要的。

由于健康与安全的原因,所有具有药典标准的包装形式的水要求是无菌的,因为这些水的一些预期用途有此要求。

USP认为大批量专论水的微生物规范是不适当的,并且未被包括在这些水的专论中。

这些水可以被用于不同的用途,一些要求严格的微生物控制,而一些却未要求。

对于一给定大批量水来说,所需的微生物规范取决于其用途。

对于一些没有相关规范和检测的使用者来说,将不必需负担此难于控制的(水的微生物)属性的单个规范。

然而,一些应用可能需要甚至更加严格的微生物控制,以避免微生物的繁殖,而微生物在水的纯化、贮存和分配过程中无处不在。
