    A housing seals in anything that could ignite flammable material, so you can use these switches where explosive gas, dust, and fibers may be. They actuate with a quick push. You’ll know they’re safe because they’re UL listed and meet NEC Class I, Division 2, Groups A, B, C, and D for hazardous locations. Install them in a standard panel cutout. The buttons are distinct colors to help you identify switches without reading labels.
    Switches come with a contact block for each number of circuits they control.
    Illuminated—Those that are illuminated make switches easier to see in low light.

    Hazardous Location 30 mm Panel-Mount Lever Switches

    Image of Product. Front orientation. Lever Switches. Hazardous Location 30 mm Panel-Mount Lever Switches.
    Made for areas where ignitable gas and vapor may be present, these switches have a housing that seals in anything that could spark flammable material. You'll know they're safe because they're NEC Class 1, Division 2, Groups A, B, C, and D certified for hazardous locations. They're also UL and C-UL listed and CSA certified. They require you to grip and twist a lever to turn them on or off, so they won’t accidentally actuate if you bump into them. Mount into a standard panel cutout.

    Circuit Board Magnetically Actuated Switches

    Mounted to your circuit board, these switches trigger when magnetic components get near, and reset as they move away. They’re often used to turn on electronics, such as starting up a laptop when you open it. To install, push the contacts through holes in a circuit board, then solder them in place.
    Plastic Housing
    Image of Product. Front orientation. Magnetic Switches. Circuit Board Magnetically Actuated Switches, Plastic Housing.
    Switches with a plastic housing withstand impact better than switches with a glass housing. The plastic also forms an airtight seal to block out contaminants. Use them in dusty or dirty environments where an optical switch might fail.

    Sealed for safety, these relays are a good choice for hazardous locations where combustible or corrosive gases may be present.
    Screw Terminals—Relays with screw terminals are considered interface relays, so they’re placed between your controller and components to isolate the input and output circuits. This means they protect your component from voltage spikes while amplifying the relay’s signal and reducing interference for reliable transmission. They are often used for switching applications, such as small motors and pilot lights. The included relay socket mounts on 35 mm DIN rail (also known as DIN 3 rail).
    Spring-Clamp Terminals—Relays with spring-clamp terminals are considered interface relays, so they’re placed between your controller and components to isolate the input and output circuits. This means they protect your component from voltage spikes while amplifying the relay’s signal and reducing interference for reliable transmission. They are often used for switching applications, such as small motors and pilot lights. The included relay socket mounts on 35 mm DIN rail (also known as DIN 3 rail). Relays with spring-clamp terminals connect and disconnect to wires without needing to turn screws. With no screws to shake loose with vibration, the terminals hold tight over time.
    Circular-Pin Terminal and Quick-Disconnect Terminal—Relays with circular-pin terminals or quick-disconnect terminals are hermetically sealed—completely air- and watertight—to shield internal parts from gases, moisture, and other contaminants. They plug into relay sockets (sold separately) for easy installation.
    Sockets with Screw Terminals—Relay sockets mount to 35 mm DIN rail (also known as DIN 3 rail) or flat surfaces.

    Differential Pressure Switches with Dial Indicator for Liquids

    Image of Product. Front orientation. Differential Pressure Switches. Differential Pressure Switches with Dial Indicator for Liquids.
    To check the difference in pressure between two points, these switches have a dial indicator that shows differential pressure in real time. The dial indicator operates independently of the switch. You’ll sometimes see these switches used to indicate a filter is clogged in a pump or cooling system. When the differential pressure reaches your setpoint, they turn equipment on and off, activate automated controls, or signal alarms. They are single pole, double throw (SPDT) and can be installed to turn one circuit from off to on or from on to off.
    Rated NEMA 4X, these switches protect against dirt, washdown, and corrosion. They are also rated IP65 for protection from dust and rinsing. All are CSA certified, so they meet Canadian safety standards.

    Hazardous Location 30 mm Panel-Mount Key Switches

    Image of Product. Front orientation. Key Switches. Hazardous Location 30 mm Panel-Mount Key Switches.
    Designed for use near ignitable gases, fibers, and dust, these switches have a housing that seals in anything that could ignite flammable material. You’ll know they’re safe because they’re NEC Class 1, Division 2 Groups A-D and NEC Zone 1 Groups IIC-IIA certified for hazardous locations. These switches require a key to turn circuits on or off, preventing accidental actuation and limiting access to sensitive equipment. Since they’re keyed alike, all open with the same key. Install them in a standard panel cutout.

    Shown Mounted (Enclosure Not Included)

    From chemical plants to refineries, these HMIs let you safely control and monitor equipment in areas where flammable and combustible gases, vapors, and liquids may escape from leaks or failures. They’re rated for use in NEC Class 1, Division 2 hazardous locations. Since they come with a touchscreen and software designed specifically to integrate with your PLC, you don’t need to spend time or money on the complex setup and extra equipment of industrial PCs.
    The manufacturer’s free PC software guides you through communication setup and screen design using drag-and-drop tools. Preview your layout, test navigation, and catch design errors before you connect to any equipment. When you’re ready, transfer your setup to the HMI with a USB cord, memory card, or Ethernet cord.
    All of our HMIs support the PLCs we currently offer, plus those from systems such as Allen-Bradley and Siemens.
    When mounted in an enclosure, the front of these HMIs is NEMA 4X and IP rated for protection against dust and light washdowns.
    All of these HMIs are compatible with RFID readers.
    Pressure Activated Touchscreen
    HMIs with a pressure-activated touchscreen respond to firm pressure, so you can use them while wearing gloves. They also work with a stylus, screwdriver handle, and other hard objects.
    Built-In RFID Antenna—HMIs with a built-in RFID antenna let you log in and trigger actions without external readers, reducing components that could spark or fail.
    Number of Supported Communication Drivers—Use the number of supported drivers to gauge compatibility. If your PLC is common, HMIs with fewer drivers likely support it, so you won’t need to pay for extra compatibility. To view the full list of supported PLCs, barcode scanners, and other devices, click on a part number and select "Product Detail." Drivers for specific PLCs save you setup time. However, you can always use a standard protocol such as Modbus RTU or EtherNet/IP—just expect more manual setup.
    Maximum Screen Brightness—Maximum screen brightness is measured in candelas per square meter (cd/m2). 400 cd/m2 is similar to an office monitor, 800 cd/m2 suits bright factory floors, and 1200 cd/m2 stays visible even in direct sunlight.

    Screen Protectors
    Add a screen protector to take the hits and scratches before your HMI does. They’re tested to meet ASTM D3363 7H standards for hardness, so they’ll stand up to sharp objects. A chemical-resistant coating also withstands grease, oil, and cleaners.
