Optek OPB720A Manuals

OPTEK Long Distance Reflective Switch OPB720A and OPB720B Series. The OPB720A and OPB720B Series reflective switches detects objects as far away as 12” (305 mm) using standard 90% reflective material, and can detect objects as small as 0.08” (2 mm).

OPTEK OPB720A and OPB720B series long distance reflective switches can detect objects up to 12 inches (305 mm) using standard 90% reflective material, and can detect objects as small as 0.08 inches (2 mm).

The OPB720A Series reflective switches detect objects as far away as 24” (610 mm) using standard 90% reflective material, and can detect objects as small as 0.08” (2 mm). The OPB720A sensor is not affected by ambient light in most conditions, as it compensates for ambient light using a synchronous driver detection scheme. It has a logical output that switches from a high level with no reflection target to a low level with a reflection target. The OPB720A series minimizes switching oscillations on the output by adding hysteresis. The series can be used in either a reflective or interruptive mode depending on the type of material used for the target.
