trigger circuits and output transistors.

1 Features: Dual channel outputs for Quadrature output Open collector inverter outputs. (.24 mm) sensor apertures for high resolution Snap mount Product Photo Here Description: The and device consists of an infrared emitting diode and a monolithic integrated circuit which incorporates two independent photodiodes, linear amplifiers, Schmitt trigger circuits and output transistors. The features a dual TTL output that is compatible with TTL/LSTTL and can drive 8 TTL loads. The has a K Ω pullup output with EMI protection on each channel. Applications include linear and rotary encoders with high resolution provided by internal. (.24 mm) apertures located in front of the Photologic sensor on.4 (1.2 mm) center line spacing. Custom electrical design, wire length and connectors are available. Contact your local representative or OPTEK for more information. Applications: Mechanical switch replacement Speed and direction indication Mechanical limit indication Rotary encoders Edge sensing Sliding door automotive and liftgate applications Part Number LED Peak Wavelength 89 nm Ordering Information Sensor Output Dual TTL K PullUp Slot Width / Depth Aperture Emitter/Sensor." /.3. /.1" Wire Length AWG Flat VREG 4Vcc VREG 4Vcc 3Out B K 3Out B.1µf K 2Out A.1µf 2Out A 1GND 1GND Page 1 of
