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.

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

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

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

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.

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

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

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.

Actuate these switches with a fraction of the force of other subminiature switches for increased responsiveness. Among the smallest snap-acting switches we offer, they fit into the tiniest of spaces.

Smaller and more sensitive than standard snap-acting switches, these switches fit in tight spaces and actuate from light pressure.

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

Press these switches with your foot for convenient, hands-free operation.

Mount proximity switches into a panel cutout or tank wall.

Support flow and temperature control in your system with these intrinsically safe switches, which sense when a valve is open or closed in volatile areas. They are ATEX and IECEx certified to protect against explosion.

Switches accept both AC and DC input voltage.

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

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

Sense objects as they pass through the switch’s ring via tubing or a funnel. These switches are often used to monitor blockages, detect breaks in spooling wire, or count small metallic parts, such as screws, during the stamping process.

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

Mount these intrinsically safe switches to flat surfaces in volatile areas. Their low-current, low-voltage NAMUR signal means they won’t ignite or create sparks while in use. ATEX and IECEx certified, they meet international standards to protect against explosion where combustible dust and flammable gases are present.

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.

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.

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.

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

Most often found in older devices, these switches require AC input voltage.

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

Also known as an air-to-electric switch, this relay converts an air signal to an electric signal.

Often used to extend and then retract a cylinder at different speeds, these valves create two actions and have two exhaust ports, which allows you to control the speed of each action by attaching a flow control valve to each exhaust port. They activate when an object, such as a box rolling on a conveyor, pushes the actuator. Also known as 4-way and 5/2 valves.

Because they require a key to operate, you can limit who is able to adjust these valves. They create one action, such as extending a cylinder.

To prevent accidental start-up, these valves can be locked in their off position with a padlock. They create one action, such as extending a cylinder.

The push buttons that operate these valves are separate from the logic unit, allowing you to position them away from machinery. Since both hands are required to simultaneously press the buttons, they protect workers from accidental machinery start-up. They create one action, such as extending a cylinder.

In the off position, these valves exhaust all air pressure, allowing the equipment to return to the neutral position. Also known as 4/3 exhaust-center valves, they create two actions, such as extracting and then retracting a double-acting cylinder.

These valves create one action, such as extending a cylinder. Use your foot to operate them, leaving your hands free to perform other tasks. Also known as 3-way or 3/2 valves.

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.
