OPB920BZ

     Non-contact switching Right Angle Sensor: LED in tower, photosensor in base Choice of output configuration Optical line can be broken in three axis 24” minimum, 26 AWG UL approved wire leads The OPB920 series optical switch consists of an infrared emitting diode (LED) and a photologic sensor . The LED is mounted on the tower with the photologic sensor mounted on the base of a right angle shape package . The L-Shape or right angle package configuration allows for an opaque object to block the light beam from a multitude of directions including the Xaxis Y-axis and Z-axis. The optical center line between the emitter and photosensor is at 45° from the mounting base of the device. The OPB920 Series provides optimum flexibility for the design engineer. The engineer can specify the type of TTL output. For example the output can be: TTL totem pole, TTL open collector, either of which can be buffered or inverted output. All versions have the added stability of hysteresis built into the circuitry. Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK for more information.
