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.

Features:

• Choice of aperture size

• Choice of output configurations

• Choice of opaque or IR transmissive shell

• Choice of pins (L) or wires (W)

• 0.125” (3.18 mm) slot width

• 0.320” (8.128 mm) lead spacing for PCBoard (side mounting)

• Data rates to 250 kBaud

Applications:

• Mechanical switch replacement

• Speed indication (tachometer)

• Mechanical limit indication

OPB940W51Z属于传感器，变送器 > 光学传感器 - 光电遮断器 - 槽型 - 逻辑输出。梯梯电子集成制造服务(苏州)有限公司制造生产的OPB940W51Z光学传感器 - 光电遮断器 - 槽型 - 逻辑输出逻辑输出、槽型光断续器产品族中的产品将光源和匹配的光电检测器以相对的方向集成在一起，连同支持电路用于以二进制（双态）方式确定发射器与接收器之间的空间中是否存在不透明物体或材料。由于它们采用了额外的接收端处理，因此与同名的晶体管输出器件不同，后者则是以牺牲应用灵活性为代价来简化应用的。
