OPB821S3Z Datasheet | TT Electronics

Slotted Optical Switch OPB820S, OPB821Z, OPB821S_Z 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 OPB820S OPB821Z Description: Each OPB820S 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...
