The OPB720 is a reflective switch designed to detect objects as far away as 24” (610 mm). Detectable object
sizes can be as small as 0.08” (2mm) at a distance of 8” (20 mm). The OPB720 has a logical output that
switches from a high level with no reflection target to a low level with a reflection target. With the addition of
hysteresis, the OPB720 minimizes switching oscillations on the output. The open collector output transistor
and power requirements is compatible with most PLC’s
