Description
The OPB760T series of reflective
assemblies feature Photologic
®
output. This electrical output can be
specified as either TTL Totem Pole or
TTL Open Collector. Either may be
supplied with inverter or buffer output
polarity. All have the added stability of a
built-in hysteresis amplifier.
