Photologic Slotted Optical Switch OPB120A, OPB120B, OPB121A, OPB121B OPB122A, OPB122B, OPB123A, OPB123B Features: Choice of output configuration Printed circuit board mounting Product Photo Here Opaque plastic housing Low profile 0.080 (2.03 mm) wide slot 0.275 (6.99 mm) lead spacing Description: The OPB120 through OPB123 devices consist of an infrared emitting diode and a Photologic sensor (which is a monolithic integrated circuit that incorporates a linear amplifier and a Schmitt Trigger). The OPB120 series have an LED and Photologic sensor mounted on opposite sides of a 0.080 (2.03 mm) wide gap of an opaque housing. The OPB12 A series have a molded 0.040 (1.02 mm) wide apertures located over both the emitter and the Photologic sensor. The OPB12 B seriesseries have a molded 0.040 (1.016 mm) wide apertures located over the emitter and 0.010 (0.254 mm) over the Photologic sensor. All devices in this series have the added stability utilizing hysteresis built into the amplification circuitry. The electrical output can be specified as either buffered Totem-Pole (OPB 120A, OPB120B), buffered Open- Collector (OPB121A, OPB121B), Inverted Totem-Pole (OPB122A, OPB122B), or Inverted Open-Collector (OPB123A, OPB123B). Custom electrical, wire and cabling and connectors are available. Contact your local representative or OPTEK for more information.
