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

Harsh Environment Photoelectric Switches

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

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).

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

Precision Photoelectric Switches

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

Long Distance Light Beam Safety Barrier Switches

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

Light Beam Safety Barrier Switches

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

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.

Space-Saving Photoelectric Switches

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

Easy-Install Photoelectric Switches

These switches have a receiver built into the housing, eliminating the need to align components and measure sensing distance during installation.

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.
