OPB821S5Z

Slotted Optical Switch OPB820, OPB821Z, OPB821S Z OPB820 Features: Non-contact switching Four standard aperture sizes for high resolution Product Photo Here Low profile 0.080 (2.03 mm) wide, 0.250 (8.89 mm) deep slot Choice of PCBoard or wire mountings OPB821Z 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). Custom electrical, wire and cabling and connectors are available.
