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.

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

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.

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.

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.

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

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

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

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.

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.

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.

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.

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.

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.

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