OPBA303

Photologic® Dual Channel Encoder OPBA301, OPBA303 Features:  Dual channel outputs for Quadrature output  Open collector inverter outputs  0.010” (0.254 mm) sensor apertures for high resolution  Snap mount Product Photo Here Description: The OPBA301 and OPBA303 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 OPBA301 features a dual TTL output that is compatible with TTL/LSTTL and can drive 8 TTL loads. The OPBA303 has a 10K Ω pull-up output with EMI protection on each channel. Applications include linear and rotary encoders with high resolution provided by internal 0.010” (0.254 mm) apertures located in front of the Photologic® sensor on 0.040” (1.02 mm) center line spacing. Custom electrical design, wire length and connectors are available. Contact your local representative or OPTEK for more information. Applications: Ordering Information  Mechanical switch replacement  Speed and direction indication  Mechanical limit indication  Rotary encoders  Edge sensing  Sliding door automotive and Part Number LED Peak Wavelength OPBA301 Sensor Output Slot Width / Depth Aperture Emitter/Sensor Wire Length 0.200" / 0.350” 0.05” / 0.01" 24” 22 AWG Flat Dual TTL 890 nm OPBA303 10K Pull-Up liftgate applications OPBA301 VREG AMP OPBA303 4-Vcc 4-Vcc VREG 10K 3-Out B AMP 3-Out B 0.01µf AMP 2-Out A AMP 1-GND 10K 2-Out A 0.01µf 1-GND OPTEK Technology is TS 16949:2002 certified, any changes will be consistent with TS 16949:2002 procedures.
