Screw these controls into a light bulb socket.

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

Also known as fork sensors and slot sensors, these switches have a receiver built into the housing, eliminating the need to align components and measure sensing distance during installation.

Light beams travel up to 32 ft. between the transmitter and receiver.

Set these switches to delay activation by up to fifteen seconds after detecting an object.

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.
