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

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.

About half the size of most standard photoelectric switches, these fit comfortably in tight spaces. The transmitter and receiver are built into the housing, so you don’t need to align components or measure sensing distance to install them.

Detect objects as thin as a freshly sharpened pencil tip. These switches are best for tight spaces because they have a smaller light beam and can detect smaller objects than standard photoelectric switches.

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

Spanning up to 230 ft.—roughly the length of a commercial airplane—these safety barrier switches cut power to large machinery to prevent damage or injury.

The highly flexible fiber-optic cable and small sensing end help you position these switches in hard to reach areas.
