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
?/DIV>
sensor on
0.040" (1.02 mm) center line spacing.
