De scrip tion
The OPB950 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 outputs are
TTL/LSTTL compatible and can drive 8
TTL loads.
Applications include linear and rotary
encoders with high resolution provided
by internal 0.010" (0.254 mm) apertures
located in front of Photologic
sensor on
0.040" (1.02 mm) center line spacing.
