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

With a narrow, flat body, these switches fit in tight spaces.

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

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.

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

Transmit a beam of light up to 225 ft. from the transmitter to the receiver.

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

Screw these controls into a light bulb socket.

To provide more mounting flexibility than other sensor and switch mounting brackets, the head rotates 360°.

The spring-loaded design absorbs impact to protect sensors and switches from damage.

With strength for higher load capacities than other ball-grip positioning arms, these arms have a heavy duty construction.
