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

Sealed actuators prevent these switches from jamming, even when exposed to oil, sand, mud, or ice.

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

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

Secure these switches into panel cutouts using mounting nuts. They have a slim body so they can also be stacked together or fit into 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.

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.

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 IP67, these switches have an enclosure that shields their interior during temporary submersion. They open and close circuits in a snap—their quick actuation minimizes arcing and keeps contacts from sticking.

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

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

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.

Trigger actions in devices as small as phones and drones. The smallest snap-acting switches we offer, these switches fit into the tiniest of spaces and help keep weight to a minimum.

Made of polycarbonate, these switches won't wear down even as objects constantly bump into them, unlike rubber bumper switches.

Minimize false triggers—these switches require 10 lbs. of actuation force in order to shut off machinery immediately.

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.

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.

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.

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

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.

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.

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.

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.

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

Switches accept both AC and DC input voltage.

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

Easily mount these flat switches to a base or rail.

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.

About half the size of most standard photoelectric switches, these fit comfortably in tight spaces. The transmitter and receiver are built into the housing, so you don’t need to align components or measure sensing distance to install them.

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

With a narrow, flat body, these switches fit in tight spaces.

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.

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

Monitor a wide area around dangerous machinery. If a person or object gets too close, these scanners signal your relay or controller to either trigger a warning or shut down the machinery.

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.

Light beams travel up to 32 ft. between the transmitter and receiver.

Send signals in response to changing magnetic fields to trigger processes or monitor position, speed, and current.

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.

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°.

For hands-free entry, these switches send a door-opening signal when they detect motion.

Position your sensor exactly where you need it for your conveyor setup.
