Slotted Optical Switch OPB827, OPB828, OPB829Z Series OPB827 OPB828 Features:  0.125” (3.18 mm) wide, 0.315” (8.00 mm) deep slot  0.305” (7.75 mm) lead spacing (OPB827)  0.220” (5.59 mm) lead spacing (OPB828) OPB829Z  24-inch 26 AWG wire leads (OPB829)  Inexpensive plastic housing Description: Each OPB827, OPB828 and OPB829 device consists of an infrared emitting diode (LED, 890 nm center wavelength) and a NPN silicon phototransistor, mounted on opposite sides of a 0.125” (3.18 mm) wide slot in a low-cost black plastic housing. A variety of aperture sizes are offered (see chart below). The OPB827 and OPB828 are designed fro PCBoard mounting with a minimum lead length of 0.35” (8.9 mm) while the OPB829Z (wire version) has 24-inch 26 AWG wire leads. Phototransistor switching occurs when an opaque object passes through the slot. The OPB827 is offered with 0.305” (7.75 mm) and the OPB828 is offered with 0.220” (5.59 mm) lead spacing for PCBoard mounting. The OPB829Z has 24” (61 cm) 26 AWG wire leads for remote mounting. Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK for more information.
