Switches

DIN-Rail Mount Miniature Toggle Switches

Built into a terminal block, these switches mount to DIN rail.

DIN-Rail Mount Enclosed Toggle
Switches with Receptacle

Snap these switches onto your DIN rail to mount them. With a toggle switch and receptacle combined, you can actuate power and plug in devices from a single box.

Surface/DIN-Rail Mount Set-to-the-Minute
Time and Day Activated Switches

Mount these switches to a flat surface or attach to DIN rail.

Surface/DIN-Rail Mount Time
and Day Activated Switches

Mount these switches to a flat surface or attach to DIN rail.

Barriers for Hazardous Location Proximity Switches

Safely transmit power to switches and sensors in highly volatile areas. Commonly used in refineries, power plants, and wastewater-treatment facilities, these barriers use a NAMUR signal to reduce the current and voltage coming from your power supply—preventing sparks and ignition.

DC Metallic-Object Proximity
Switches with Digital Display

Actuate your switch with precision—these proximity switches have an easy-to-read screen for precise distance inputs, measurements, and troubleshooting.

DIN-Rail Mount Disconnect Switches

Often used in electrical enclosures, these switches mount directly to DIN rails. They cut power and keep it isolated to stop equipment from starting up during inspection and maintenance.

Enclosure Disconnect Switches

Install these switches inside an enclosure to prevent it from opening when power is on—turn the switch to disconnect power and release the door.

Manual Override Enclosure Disconnect Switches

Keep power running while you access your enclosure. Unlike standard enclosure disconnect switches, which shut off power as you open your enclosure, these have an override function.

Enclosure Motor Switches

Designed to mount on an electrical enclosure, these switches control motors, lighting, and electric heat circuits.

Ethernet Switches

DIN-Rail Mount Ethernet Switches

Mount these Ethernet switches to DIN rail to bring connections closer to where you need them.

ix Industrial Ethernet Switches

Link industrial equipment with multiple computers to expand your data network.

Temperature Controllers

On/Off Temperature Controllers for Plug-in Heaters

Switch heaters on or off when your process reaches a certain temperature. Both these controllers and your heater will be powered by the same wall outlet.

DIN-Rail-Mount Autotuning Temperature Controllers

Mount these temperature controllers directly onto DIN rail for controlling systems with rapid, unpredictable, or complex temperature changes. They turn heating equipment on and off using a proportional-integral-derivative (PID) control algorithm to make fine adjustments, giving you the most precise and stable temperature control.

Washdown Autotuning Temperature Controllers

The faceplate on these controllers is sealed to meet NEMA 4X and IP66 for protection in washdown environments with splashing water, corrosive liquid, and dust.

Autotuning Temperature Controllers

Ideal in systems with rapid, unpredictable, or complex temperature changes, these controllers turn heating equipment on and off using a proportional-integral-derivative (PID) control algorithm to make fine adjustments, giving you the most precise and stable temperature control.

High-Limit Temperature Controllers

To protect equipment and personnel, these controllers shut down your machine when it gets too hot.

Proportional Temperature Controllers

Cycle heaters on and off intermittently to maintain a set temperature in your system.
