Choosing a Proximity Switch

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.

Harsh Environment Photoelectric Switches

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

DC Metallic-Object Proximity Switches

These switches use DC input voltage and produce PNP or NPN signal output. They're often used with programmable logic controllers (PLCs).

DC Metallic-Object Proximity
Switches for Long Distances

Sense objects from farther away than with other DC proximity switches that have the same diameter.

No-Distance-Correction DC
Metallic-Object Proximity Switches

Eliminate the need to calculate the sensing distance when using different metals—these switches sense all metal at the same distance. Also known as K=1 sensors.

Hazardous Location Rotatable DC
Metallic-Object Proximity Switches

Twist the sensor to detect metallic objects where explosive dust or gas may be present—the sensor rotates for front, side, top, or bottom sensing. These switches are UL and C-UL listed as well as ATEX and IECEx certified for hazardous locations.

Rotatable DC Metallic-Object Proximity Switches

Turn the face on these switches to sense metallic objects from the front, sides, top, or bottom.

AC Metallic-Object Proximity
Switches for Long Distances

These switches have a longer sensing distance compared to other proximity switches with the same diameter.

DC Universal-Object Proximity Switches

Often used with programmable logic controllers (PLCs), these switches use DC input voltage and produce PNP or NPN signal output.

Harsh Environment DC
Universal-Object Proximity Switches

Rated NEMA 4X, 6P, IP68 and IP69K, these switches resist corrosion and high-pressure, high-temperature washdowns, and can withstand temporary submersion.

Level Switches

Noncontact Level Switches for Conductive Liquids

Measure the level of conductive liquids without drilling a hole in your tank—these switches mount to the outside of the tank and track the capacitance between them and the tank’s contents.

Sanitary Level Switches

Detect when oil rises on water, foam forms on beer, and tanks empty, triggering pumps and valves in food and sanitary lines. These switches are 3-A and European Hygienic Engineering and Design Group (EHEDG) certified since they’re easy to keep clean.
