Photologic Dual Channel Encoder OPB950Z, OPB951 Features: Dual channel outputs for Quadrature Output Package 1 Open collector inverter outputs 0.010 (0.254 mm) sensor apertures for high resolution Package 2 Snap mount OPB950 5.0.5 Volt Vcc, OPB951 4.75 to 16 Volt Vcc RoHS Description: Each OPB950, series devices consists of an infrared Light Emitting Diode (LED) and a monolithic integrated circuit which incorporates two independent photodiodes, linear amplifiers, Schmitt trigger circuits and output transistors. The device is oeff red in two versions (see page 2 for package drawings). The OPB950 features a dual open -collector output that is compatible with TTL/LSTTL and can drive up to 8 TTL loads. The OPB951 brings out the anode of the LED for custom power applications. Applications include linear and rotary encoders with high resolution provided by internal 0.010 (0.254 mm) apertures located in front of each Photologic sensor on 0.040 (1.02 mm) center line spacing. Custom electrical, wire, cabling and connectors are available. Contact your local representative or OPTEK for more information.
