Wide Beam Photoelectric Switches
Detect irregularly shaped items with a band of light up to 10 times larger than the beam on a standard photoelectric switch. The wide beam makes them a great choice when material moving down your line varies in size and shape. Because they’re photoelectric, they don’t make contact with items like other actuators do, and they can detect objects that are moving quickly. They produce PNP or NPN signal output. To determine the signal output of a switch you are replacing, use Testers for Proximity and Photoelectric Switches (not included).
Direct sensing switches project light onto an object and then detect the reflection to actuate. The transmitter and receiver are in the same housing, so these switches fit in tight spaces. Use them to detect small material with irregular shapes, such as circuit boards. Those with a delayed off function can stall activation by up to one second after sensing an object.
Adjustable switches can increase the intensity of the light beam to better detect shiny or translucent objects.
