Dual Channel Encoder
Type OPB950
Features
• Dual channel outputs
• 0.010" (0.254 mm) sensor apertures
for high resolution
• Open collector inverter outputs
• Snap mount
• 4-pin connector ( Ho Tien 2560-04),
Molex compatible connector 5102
series housing and 5103 series
terminal
Description
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.
