Description:

Each OPB821TX and OP821TXV device consists of a gallium aluminum arsenide LED and a silicon phototransistor, which are soldered into a printed circuit board and mounted in a high temperature plasƟc housing on opposite sides of an 0.080” (2.03 mm) wide slot. Lead wires are #24 AWG polytetraflouroethylene (PTFE) insulated, which conforms to MIL‐W‐ 16878.

Phototransistor switching takes place when an opaque object passes through the slot. For maximum output signal, neither the LED nor the phototransistor is apertured.

TX and TXV device components are processed to OPTEK’s military screening program paƩerned aŌer MIL‐PRF‐19500.

Features:

• Non-contact switching

• Low profile to facilitate stacking

• Hermetically sealed components

• 24” (609.60 mm) minimum length wire conforms to MIL-W-16878

• TX and TXV components processed to MIL-PRF-19500

Applications:

• Non‐contact object sensing

• Assembly line automaƟon

• Machine automaƟon

• Equipment safety

• Machine safety

OPB821TXV属于传感器，变送器 > 光学传感器 - 光电遮断器 - 槽型 - 晶体管输出。梯梯电子集成制造服务(苏州)有限公司制造生产的OPB821TXV光学传感器 - 光电遮断器 - 槽型 - 晶体管输出具有晶体管输出的槽型光断续器是利用内置红外光源和以气隙（槽）隔开的光电二极管的光学传感器模块。当致动器、液体或其他检测物体挡住光源时，将打开或关闭输出晶体管，从而切换施加的电压。安装方式包括底座、卡入、表面、自由悬挂和通孔安装。
