Use these switches where ignitable gas and dust may be present. Their contact blocks are UL listed for Class I, Division 2, Groups B, C, and D hazardous locations.

More lightweight than steel or stainless steel, these aluminum enclosed switches are rated NEMA 4X for protection from corrosion and washdowns.

Use these switches where ignitable gas, dust, and fibers may be present. They're UL and C-UL listed for hazardous locations.

Use these switches where ignitable gas and dust may be present. They meet NEC Class I, Divisions 1 and 2, Groups B, C, and D; and Class II, Divisions 1 and 2, Groups E, F, and G for hazardous locations.

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.

Mount these intrinsically safe switches to flat surfaces in volatile areas. Their low-current, low-voltage NAMUR signal means they won’t ignite or create sparks while in use. ATEX and IECEx certified, they meet international standards to protect against explosion where combustible dust and flammable gases are present.

Safely detect the presence or absence of an object moving at high speeds with a light beam. These switches produce a low-current, low-voltage NAMUR signal, so they won’t create sparks or ignite. ATEX and IECEx certified, they protect against explosion in environments containing flammable gases and combustible dust.

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.

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.

Often used to control heat cable output, these switches have mounting holes for surface installation.

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.

Designed for use in areas where flammable substances are present, these switches are CSA certified for hazardous locations.

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

Alter the set point with the adjustment screw to suit your application.

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.

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.

Set to a specific speed to detect unwanted machinery slowdown that can cause damage and downtime.
