Descripꢀon:
Each OPB950, series devices consists of an infrared Light Emiꢂng Diode (LED) and a monolithic integrated circuit which
incorporates two independent photodiodes, linear amplifiers, Schmiꢀ trigger circuits and output transistors. The device is
offered in two versions (see page 2 for package drawings). The OPB950 features a dual open-collector output that is
compaꢁble with TTL/LSTTL and can drive up to 8 TTL loads. The OPB951 brings out the anode of the LED for custom power
applicaꢁons.
Applicaꢁons include linear and rotary encoders with high resoluꢁon 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 representaꢁve or OPTEK for more
informaꢁon.
