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.

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

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

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

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.

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.

Prevent equipment from automatically restarting—these switches must be manually reset each time they're actuated.

Open and close circuits in a snap—even in harsh conditions. With a rubber-encased housing and stainless steel bracket, these switches handle high vibrations and resist corrosion. They’re rated IP68 for protection from dust and temporary submersion.

Enclosures protect these snap-acting switches from the environment.

Keep out dirt and moisture—the sealed housing on these switches is watertight and meets MIL-PRF-8805.

Smaller than standard size snap-acting switches, these fit in tight spaces.

Built for tight spaces exposed to water, these switches have a housing that's less than 1" long and IP67 rated for protection from temporary submersion.

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

Sensitive along their entire length, these switches are often used to signal when an overhead door closes or an item reaches the end of a conveyor.

Prevent automatic doors from closing on a person or an object—these switches immediately turn machinery off when actuated with minimal force.

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

These inductive proximity switches sense metallic objects each time they pass through the slot, even when they’re obscured by water, oil, dirt, or a surface finish. Use them to measure the speed of rotating equipment and to count or detect moving objects, such as sheet metal being fed into a stamping process.

These intrinsically safe switches detect objects as they’re routed through the ring. They produce a low-current, low-voltage NAMUR signal, so they won’t ignite or create sparks. Switches are ATEX certified to protect against explosion.

The short body on these switches makes them suitable for tight spaces.

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

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.

Check the position of your torch or workpiece for accuracy during robotic welding.

For use in volatile areas, these intrinsically safe switches detect objects when they pass through the slot. They use a NAMUR signal to operate at a low current and voltage, so they won’t ignite or create sparks. ATEX and IECEx certified, they protect against explosion.

With a smaller diameter and shorter length than standard sized switches, these fit in the most space-constrained areas.

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

Rotate the face on these switches five different directions for easy installation and positioning—they work with both AC and DC inputs.

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

These switches use a NAMUR signal to operate at a low current and voltage, so they won’t ignite or produce sparks. ATEX certified, they protect against explosion in environments containing flammable gases and combustible dust. Switches sense both metallic and nonmetallic objects.

Mount proximity switches into a panel cutout or tank wall.

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

Detect objects as thin as a freshly sharpened pencil tip. These switches are best for tight spaces because they have a smaller light beam and can detect smaller objects than standard photoelectric switches.

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

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.

A slim design and a light beam that’s angled upwards allow these switches to sense objects from between conveyor rollers.

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.

The highly flexible fiber-optic cable and small sensing end help you position these switches in hard to reach areas.

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

These switches detect magnetic objects—or objects with a magnet attached—through non-magnetic walls.

These switches sense when a valve is open or closed, supporting flow and temperature control within your system and offering reliable feedback.

Position proximity, photoelectric, and light beam sensors and switches.

To provide more mounting flexibility than other sensor and switch mounting brackets, the head rotates 360°.

Designed to fit most limit switches, these brackets allow switch-position adjustments after they are fastened to equipment.

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.
