Choosing a Proximity Switch

Light-Sensing Light Controls

Wire these controls to light fixtures.

Light-Sensing Controls for Light Bulbs

Screw these controls into a light bulb socket.

Proximity Switches

Photoelectric Switches

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.

Reflectors for Photoelectric Switches

Space-Saving Photoelectric Switches

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

Wide-Angle Safety Barrier Switches

Scanning 275° side-to-side for people and objects, these switches (known as safety laser scanners) cover large areas and send signals to machinery to prevent accidents.

Precision Photoelectric Switches

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

Light Beam Safety Barrier Switches

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

Time-Delay Photoelectric Switches with Relay Output

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

Photoelectric Switches with Relay Output

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

Hazardous Location Photoelectric Switches

Safely detect the presence or absence of an object moving at high speeds with a light beam. These switches produce a low-current, low-voltage NAMUR signal, so they won’t create sparks or ignite. ATEX and IECEx certified, they protect against explosion in environments containing flammable gases and combustible dust.
