Photoelectric Sensor Adjusts Electronically

To alleviate false triggering from background objects, Banner Engineering Corp. recently unveiled a new adjustable-field photoelectric sensor that allows users to detect objects within a sensing field, while more effectively ignoring reflective objects beyond the sensing field cutoff point.

To alleviate false triggering from background objects, Banner Engineering Corp. recently unveiled a new adjustable-field photoelectric sensor that allows users to detect objects within a sensing field, while more effectively ignoring reflective objects beyond the sensing field cutoff point.

Banner's 10 to 30 V, dc-powered sensors enhance users' flexibility by allowing them to define unique cutoff points for each application. The sensors also feature a patent-pending electronic adjustment, rather than the mechanical adjustment used in competitive units. Available with cutoff points that range from 50 to 150 mm, or 125 to 400 mm, the sensors use a dual-element photodiode and hybrid geometry to achieve more reliable adjustment and sensor performance. The sensing field cutoff distance is adjusted using a 12-turn slotted brass potentiometer.
