OPB821S5Z传感器变送器的光学传感器-光电遮断器-槽型-晶体管输出规格书PDF中文资料

Description:

Each OPB820 and OPB821 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” (610 mm) 26 AWG wire leads (OPB821).

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
