Washdown 3/4" Panel-Mount Key Switches

Rated NEMA 4, these switches are protected from washdowns.

22 mm Panel-Mount Key Switches

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

30 mm Panel-Mount Key Switches

Install these key switches in 30 mm dia. panel cutouts. They require a key to turn circuits on or off, limiting access to sensitive equipment.

Light Beam Finger-Touch Switches

An infrared light beam senses the lightest finger contact to switch a circuit on or off.

22 mm Panel-Mount Knob Switches

Turn these switches by hand.

Battery Knob Switches

Alternate between two batteries without interrupting power.

Joystick Switches

Grab these switches by hand and pivot them to use.

Enclosed Washdown Snap-Acting Switches

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

Corrosion-Resistant Washdown Limit Switches

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

Compact Safety Limit Switches

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

No-Distance-Correction DC
Metallic-Object Proximity Switches

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.

Hazardous Location DC
Metallic-Object Proximity Switches

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.

Hazardous Location Rotatable DC
Metallic-Object Proximity Switches

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.

Photoelectric Switches with Relay Output

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

Time-Delay Photoelectric Switches with Relay Output

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

Motor Starters

Enclosed Motor Starters

The NEMA 4X rated enclosure protects these starters from corrosion and washdowns.

Enclosed Reversing Motor Starters

Rated NEMA 4X, these enclosed starters are protected from corrosion and washdowns.

Enclosed Disconnect Switches

Washdown Enclosed Disconnect Switches

Rated IP66, these switches are protected from washdowns.

Harsh Environment Potentiometers

Rated NEMA 4X and 13, these potentiometers are protected from debris, washdowns, and oil/coolant spraying.

Control of Liquids, Gases, and Solids

Autocorrecting Washdown Precision
Panel-Mount Temperature Controllers

The faceplate is sealed to meet NEMA 4X for protection in washdown environments with splashing water, corrosive liquid, and dust.

Hazardous Location Threaded Temperature Switches

Often used in hazardous locations, such as chemical plants, refineries, and grain elevators, these switches have a housing that’s UL listed for environments with flammable gases, combustible dust, and ignitable fibers.

Hazardous Location Wall-Mount Temperature Switches

Housing is UL listed for environments with flammable gases, combustible dust, and ignitable fibers, such as chemical plants, refineries, and grain elevators.

Pressure Switches

The traditional pressure switch. These power equipment, activate controls or alarms, or kick-off other actions when they reach a set pressure.

Hazardous Location Pressure Switches

Built with an explosionproof enclosure to meet NEMA 7 and 9 standards for hazardous locations, these switches were tested and verified by UL and CSA for use where explosive liquids, dust, and gas are present.

Adjustable-Reset Pressure Switches with Digital Display

Kick off automated controls, signal alarms, or activate equipment based on pressure changes while checking the pressure, setpoint, and reset point on the display.

Manual-Reset Pressure Switches

Used as a safety control, these switches must be manually reset each time they hit the set pressure, so you can inspect equipment before it restarts.

Adjustable-Reset Pressure Switches

Choose when these switches reset to control the pressure range between when they activate and deactivate, commonly referred to as deadband and differential.

Dual-Setpoint Pressure Switches

Trigger two different automated processes, each with their own set pressure.

Adjustable-Reset Vacuum Switches

Control the amount of vacuum change between when these switches activate and deactivate by adjusting when they reset.

Pressure and Vacuum Switches

Because these switches work with both positive and negative (vacuum) pressures, you can use them in applications that span both.

Noncontact Level Switches for Conductive Liquids

Measure the level of conductive liquids without drilling a hole in your tank—these switches mount to the outside of the tank and track the capacitance between them and the tank’s contents.

Level Switches for Dry Materials

When dry material rises to the level of the rotating paddle, these switches actuate.

Washdown Flow Switches for Water and Oil

For protection from dirt, washdowns, and corrosion, these switches have an enclosure that meets NEMA 4X.

Lights

Hazardous Location Flashlights

Rated for use in environments where hazardous material is present.

Articulating-Arm Dock Lights

Console Enclosures

Build out human-machine interfaces by installing buttons, switches, gauges, and other components to monitor and control machinery.

Hazardous Location Vibration-Monitoring Switches

Get NEMA 4 and IP66 protection from dirt and water. If vibration or shock exceeds a set activation point, the contacts actuate to either shut down your machine or activate an alarm.
