光电集成电路开关

Description:

The OPB930 and OPB940 series of Photologic® photo integrated circuit switches provide optimum flexibility for the design engineer. Building from a standard housing with a 0.125" (3.18 mm) wide slot, a user can specify the type and polarity of TTL output, discrete shell material, aperture width and either 0.350" (8.9 mm) long pins (L Series) or 24" (610 mm) AWG, UL listed wire leads (W Series). All housings are made from an opaque grade of injection-molded plastic that minimizes the assembly’s sensitivity to both visible and near-infrared ambient radiation. Discrete shells (exposed on the parallel faces inside the device throat) are either IR transmissive plastic (for applications where aperture contamination may occur) or opaque plastic (for maximum protection against ambient light). Electrical output can be specified as either TTL Totem Pole or TTL Open Collector, either of which can be supplied with buffer or inverter output polarity. All devices have the added stability of a built-in hysteresis amplifier. Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK for more information.

 Data rates to 250 kBaud

Applications:

 Mechanical switch replacement

 Speed indication (tachometer)

 Mechanical limit indication

 Edge sensing

OPB930和OPB940系列Photologic®光电集成电路开关为设计工程师提供了最佳灵活性。从带有0.125英寸（3.18毫米）宽插槽的标准外壳构建，用户可以TTL输出的类型和极性、离散外壳材料、孔径宽度以及0.350英寸（8.9毫米）长引脚（L系列）或24英寸（610毫米）AWG、UL认证导线（W系列）。所有外壳均由不透明等级的注塑塑料制成，可最大限度地降低组件对可见光和近红外环境辐射的敏感性。分立外壳（暴露在设备喉部内的平行面上）为红外透射塑料（用于可能发生孔径污染的应用）或不透明塑料（用于大程度地保护环境光）。电气输出可以为TTL图腾极或TTL开路集电极，其中任何一个都可以提供缓冲或逆变器输出极性。所有设备都具有内置滞后放大器的额外稳定性。可定制电气、电线和电缆以及连接器。有关更多信息，请联系当地代表或OPTEK。
