Sealed for safety, these relays are a good choice for hazardous locations where combustible or corrosive gases may be present.

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).

Relays with circular-pin terminals plug into relay sockets (sold separately) for easy installation. They are hermetically sealed.

Relay sockets mount to 35 mm DIN rail (also known as DIN 3 rail) or flat surfaces.

Safe for use in chemical plants, refineries, and other hazardous locations, these switches maintain your surface’s temperature by turning equipment on or off when they reach a set temperature. They’re FM approved for use where flammable gases may be present. These switches actuate when the temperature rises to the setpoint and reset when the temperature falls below the reset point. Since they're SPDT (single pole, double throw) switches, they control one circuit and can either be wired to turn one device from on to off (normally closed) or from off to on (normally open). Wire them normally closed to power a heater—when the temperature rises to the setpoint, the heater will turn off until the temperature falls below the reset point. Or wire them normally open to turn on alarms or other devices when the temperature rises above the setpoint. Their setpoint isn’t adjustable, so they’re easy to set up and there’s no risk of unintentional changes.

CSA-US and CSA certified, they also meet American and Canadian safety standards.

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 (normally open) or from on to off (normally closed).

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.

Rated for use in environments where hazardous material is present. These flashlights have built-in LEDs that last longer, are more efficient, and generate less heat than other light technologies.

Flashlights with a uniform beam are especially good for close-up tasks and inspection work. Flashlights with a bull’s eye beam have a bright center for long-distance illumination.

Flashlights that cannot be sold to the regions listed are restricted by local energy efficiency regulations.

Hazardous location environmental ratings indicate where manufacturers have included safety features in products to facilitate their safe use in hazardous environments. Before selecting a product for a hazardous location, ensure it is rated for your environment.

Note: Battery life is significantly reduced when flashlights are used at the high-beam light setting.

In addition to pivoting 210°, the light heads rotate 360° for directing light exactly where it’s needed. These flashlights are rated for use in environments where hazardous material is present. They’re also rated IP04 to withstand liquid splashed from all angles. With long-lasting, built-in LEDs, these flashlights are more efficient and generate less heat than flashlights with other light technologies. They cast a uniform beam that is especially good for close-up tasks and inspection work. Use the mounting magnet, clip, or retractable hook when you need to keep your hands free for work.

Rechargeable flashlight comes with a 120-volt AC charger that includes a 12-volt DC charging cord. This flashlight cannot be sold to Canada due to local energy efficiency regulations.

Note: Battery life is significantly reduced when flashlights are used at the high-beam light setting.

Rated IP07, this headlamp withstands temporary submersion in a maximum of one meter of water for up to 30 minutes. It shines light on your work while keeping your hands free. This headlamp has long-lasting, built-in LEDs that produce more light and generate less heat than other light technologies. It casts a uniform beam that's especially good for close-up tasks and inspection work. Headlamps come on an adjustable elastic strap for normal wear. For secure wear over a hard hat, they also come with a rubber strap and snap-together fastener.

Headlamps with a battery life indicator let you know how close the batteries are to needing replacement. An LED light glows green when battery life is above 80%, yellow when it’s between 20% and 80%, and red when it’s below 20%.
