The OPB720B series Reflective Switches that detects objects as far away as 12 (305mm) using standard 90% reflective material and can detect objects as small as 0.08 (2mm). The OPB720 series consist of three standard reflective switching distances -06Z for typically 6 (152mm), -12Z for typically 12 (305mm) and -30VZ for typically 30 (762mm). The sensors are NOT affected by ambient light in most conditions. Ambient light conditions are compensated by using a synchronous driver detection scheme. This sensor has a logical output that switches from a high level with reflective target to a low level with no reflective target. With the addition of hysteresis, the OPB720 series minimizes output switching oscillations. The type of material used for the target is very dependent on the distance that can be achieved for the sensor. The OPB720 series has power requirements are compatible with most PLCs and TTL gates.
