Damp-Environment Limit Switches

When a moving object contacts the actuator on these switches, they open or close a circuit. They have the rapid-closing action of a snap-acting switch, but with a larger actuator for large objects.

Build-Your-Own Limit Switches

Combine an actuator and a switch to assemble the exact limit switch you need.

Rotary Limit Switches

Start or stop equipment after a set number of rotations to avoid over-rotation.

Heavy Duty Limit Switches

Rugged enough for mining operations, these limit switches require a high actuation force, like heavy rocks moving on a conveyor.

Wireless Self-Powered Limit Switches

Install these limit switches where changing a battery or routing wires might be difficult—they power themselves when a moving object contacts the actuator.

Low-Profile Limit Switches

Stack these slim switches together, or fit them into tight spaces. They're rated IP67 for protection from temporary submersion.

Sealed Low-Profile Limit Switches

A sealed actuator prevents these switches from jamming, even when exposed to sand, mud, or dirt. With a slim design, you can stack them together or fit them in tight spaces.

Safety Limit Switches

Protect machinery and ensure the safety of personnel—these switches will open the circuit when actuated even if a spring fails or the contacts stick.

Compact Safety Limit Switches

Shorter and thinner than other safety limit switches, these are sized to fit tight spaces.

Hazardous Location Limit Switches

Safely open or close a circuit near ignitable gases and dust—the housing on these switches seals in anything that could ignite flammable material.

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.

Enclosed Washdown Snap-Acting Switches

Rated NEMA 4 , these enclosed switches have a sealed actuator for protection from washdowns.

Access Prevention Safety Switches

Frame-Mounted Safety Switches

Also known as interlock switches, these ensure the safety of personnel by automatically shutting off power to machinery when an access door opens. They’re often used with machine guards.

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.

Hinge-Actuated Safety Switches

Replace the hinges on access doors or machine guards with these switches to keep your team safe from active machinery.

Access-Delay Frame-Mounted Safety Switches

Delay access to hazardous areas until conditions are safe; use these switches with machines that take time to stop after they are turned off. They mount to a door frame.

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 DC
Metallic-Object Proximity Switches

Use these switches to sense metallic objects in environments containing flammable gases and combustible dust. ATEX and IECEx certified to protect against explosion, they produce a low-current, low-voltage NAMUR signal, so they won’t ignite or create sparks.

Rotatable DC Metallic-Object Proximity Switches

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

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.

AC Metallic-Object Proximity
Switches for Long Distances

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

Flat-Body AC/DC Metallic-Object Proximity Switches

Mount these flat inductive switches to a base or rail to remotely detect metallic objects in wet and dirty environments.

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.

AC/DC Universal-Object Proximity Switches

Switches accept both AC and DC input voltage.

Ultrasonic Switches

Detect objects and liquid or material levels to set off actions in your system—regardless of size, shape, or surface finish.

Tilt Switches

Often used as position indicators, pump level controls, and machine limit switches, these switches actuate when tilted to a certain angle.

Air-Actuated Switches

Build-Your-Own Air-Actuated Hand Switches

Combine a push-button actuator with a switching mechanism to build a complete switch.

Build-Your-Own Air-Actuated Foot Switches

Combine a foot-pedal actuator with a switching mechanism to build a complete switch.

Speed-Monitoring Switches

Detect unwanted slowdowns in your rotary shaft that could cause machine damage and downtime.

Ultrasonic Transmitters

Measure the distance to objects and the level of liquids and materials despite size, shape, or surface finish, and send that information to other parts of your system.
