Rated NEMA 6P, 13, and IP68, these switches protect against corrosion, washdowns, and temporary submersion.

Sized for 22 mm dia. panel cutouts, these switches require a key to turn circuits on or off, limiting access to sensitive equipment.

Safe for use in wet locations, these switches are IP and NEMA rated for protection from corrosion, washdowns, and oil/coolant spraying.

Often used with machine guards, these switches mount to a door frame.

These switches actuate with the slightest push for a high degree of accuracy. They're rated IP67 for protection from wet locations and temporary submersion.

Secure these switches into panels using mounting nuts.

Rated NEMA 6P, 13, and IP67, these switches are protected from corrosion, oil/coolant spraying, washdowns, and temporary submersion.

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

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

With a rubber-encased housing and stainless steel bracket, these switches resist vibration and corrosion. They're rated IP68 for protection from dust and temporary submersion.

Enclosures protect these snap-acting switches from the environment.

Small enough to fit in the tiniest spaces, these switches are rated IP67 for protection from temporary submersion.

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

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.

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.

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

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

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

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.

The flexible cable on these switches withstands applications that require frequent motion, such as robotics.

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

Easily mount these flat switches to a base or rail.

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

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.

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.
