Detect the presence or absence of an object moving at high speeds with a light beam. These switches have a longer sensing distance than proximity and ultrasonic switches.

A built-in relay produces AC voltage output. These switches are often used with older programmable logic controllers (PLCs).

For optimal performance in tight spaces, these switches have a smaller beam and can detect smaller objects than standard photoelectric switches.

Rated IP69K, these switches can withstand high-pressure, high-temperature washdowns and temporary submersion.

Verify the signal output type of DC switches—a red light indicates NPN, and a green light indicates PNP.
