With an explosionproof enclosure that meets NEMA 7 and 9 standards for hazardous locations, these switches were tested and verified by UL and CSA for use where explosive gas or dust may be present. Often used with ovens, dryers, and HVAC systems, they can indicate a filter is clogged or help maintain a certain air pressure. These switches turn equipment on and off, activate automated controls, or signal alarms when the differential pressure reaches your setpoint. 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).

In addition to being UL listed and CSA certified, these switches are CE marked and FM approved, so they also meet European safety standards. They also are IP and NEMA rated for use outdoors and protect against dust and splashing water.

When measuring pressure in ductwork, pair them with a static pressure probe.

Use to regulate line-voltage HVAC systems where flammable gases, vapors, and dust are present. Thermostats are rated Class I, Divisions 1 and 2, Groups C and D; and Class II, Divisions 1 and 2, Groups E, F, and G.

Get NEMA 4 and IP66 protection from dirt and water. Switch is rated for hazardous locations for Class I, Divisions 1 and 2, Groups C and D; and Class II, Divisions 1 and 2, Groups E, F, and G. If vibration or shock exceeds a set activation point, the contacts actuate to either shut down your machine or activate an alarm. Reset the switch with the push of a button. The activation point is adjustable between 0 to 5 gravity units (g) at 0 to 60 Hz.

Set to a specific speed to detect unwanted machinery slowdown that can cause damage and downtime. Applications include drive trains, power-driven components, and conveyors. Switches are UL listed for Class I, Divisions 1 and 2, Groups C and D; and Class II, Divisions 1 and 2, Groups E, F, and G. They have an explosion-proof housing and are also rated NEMA 4X for washdown and corrosion protection.

For use in locations with flammable gases and combustible dust, this switch is UL listed and CSA certified for Class I, Divisions 1 and 2, Groups C and D; and Class II, Divisions 1 and 2, Groups E, F, and G. Mount it vertically through the top of your tank. It’s rated NEMA 4 for protection from washdowns.

Designed for use in areas where flammable substances are present, these switches are CSA certified for hazardous locations. Mount them through a tank wall. All are rated NEMA 4 for protection from washdowns. All 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).

Switches with stainless steel body are more corrosion resistant than switches with brass body.

Safely activate and deactivate equipment in environments with flammable gases and combustible dust when your flow rate reaches a set point. They are UL listed and CSA certified for use in hazardous locations. These switches save you from disassembling your pipeline because you insert them into pipe tees or pipe outlets instead of mounting them inline. They actuate when your system’s liquid pushes the paddle into a set position. To change your set point, the paddle has multiple layers that you can remove. For the lowest set point, use the largest paddle that will fit your pipe. To increase your set point, loosen the locking washers and remove paddles. You can trim the paddles to fine-tune your set point. The smaller the paddle, the higher the setpoint.

They should be mounted vertically into a horizontal pipeline, so liquid pushes the paddle.

These switches are calibrated with water and air. They can also be used with other liquids and gases but may not measure accurately if their viscosity is significantly different.

SPDT (singe pole, double throw) switches can turn one device from off to on (normally open) or from on to off (normally closed).

DPDT (double pole, double throw) switches can either turn two devices from off to on (normally open) or on to off (normally closed).

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.
