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.

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.

Our most sensitive limit switches, these switches actuate with the slightest push for a high degree of accuracy.

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

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.

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.

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.

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.

These switches actuate when a magnet comes within sensing distance, and reset when the magnet moves away.

Wire contacts to an alarm system to alert when doors or windows are opened.

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

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.

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

Detect irregularly shaped items with a band of light up to 10 times larger than the beam on a standard photoelectric switch.

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 built-in relay produces AC voltage output. These switches are often used with older programmable logic controllers (PLCs).

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

Easily mount these flat switches to a base or rail.

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.

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.

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.

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

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.

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

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

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.

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

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

A base that lights up draws attention to emergency stops. When pushed, these switches immediately cut power.

A lightweight yet durable alternative to stainless steel enclosed switches, these aluminum enclosed switches withstand corrosion, oil, and washdowns.

Save space in your setup—these switches double as handles on machines and equipment.

A rubber seal protects these switches from splashing water.

Control equipment from up to 40 feet away—these switches include a transmitter and a receiver that connects to equipment.

Step on these switches for hands-free actuation in an area with frequent washdowns.

Send signals to equipment up to 130 feet away. Because these foot switches are self-powered, they eliminate the clutter of wires and the fuss of batteries.

The light touch of a finger turns circuits on and off without pressing down a contact. Program these switches to fit your application—control their color, pattern, and sensitivity.

Control machinery such as cranes, hoists, or trolleys with a wireless switch. About the size of a cell phone, these switches fit in the palm of your hand.
