Description:

Each OPB820 and OPB821Z device consists of an infrared emitting diode (LED, 890 nm center wavelength) and a NPN silicon phototransistor mounted in a low-cost black plastic housing on opposite sides of an 0.080” (2.03 mm) wide slot. Each device in this series has a 0.040” (1.02 mm) wide aperture located in front of the infrared diode. Phototransistor switching occurs when an opaque object passes through the slot.

Devices are offered with 0.275” (6.96 mm) lead spacing for PCBoard mounting (OPB820) or 24” (609 mm) 26 AWG wire leads (OPB821Z).

Features:

• Non-contact switching

• Four standard aperture sizes for high resolution

• Low profile

• 0.080” (2.03 mm) wide, 0.250” (8.89 mm) deep slot

• Choice of PCBoard or wire mountings

Applications:

• Non-contact object sensing

• Assembly line automation

• Machine automation

• Equipment safety

• Machine safety

OPB821Z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OPB821Z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。
