Choosing a Proximity Switch

Washdown Limit Switches

Rated NEMA 3S and IP69K, these switches can handle washdowns with high pressures and temperatures. They’re also protected from oil/coolant spraying, precipitation, and temporary submersion.

RFID Safety Switches

The convenient, modern alternative to mechanical safety switches. These RFID switches are easier to install, fit a wider range of access points, and can mount horizontally.

Frame-Mounted RFID Safety Switches

Prevent accidental bumps or vibration from triggering these safety switches unnecessarily—a strong magnet maintains the RFID signal between the actuator and switch until it's intentionally opened.

Tamper-Resistant RFID Safety Switches

Block access to machinery while it's running. These safety switches link to a single actuator, so no other RFID tag or card can interfere.

Proximity Switches

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.
