Attach these heads to your thermocouple or RTD probe to protect wiring from dust and moisture. The removable cap makes it easy to access your wiring when you need. Install an optional terminal block inside the head to keep your wiring organized.

Hazardous location connection heads are rated for use in Class I, Divisions 1 and 2, Groups A, B, C, and D; Class II, Divisions 1 and 2, Groups E, F, and G; and Class III, Divisions 1 and 2 environments with flammable gases, combustible dust, and combustible fibers.

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. It is UL listed for use in Class I, Divisions 1 and 2, Groups B, C, and D; Class II, Divisions 1 and 2, Groups E, F, and G; and Class III, Divisions 1 and 2 hazardous locations. The housing also meets NEMA 4X for use in washdown environments with splashing water, corrosive liquid, and dust. Install the threaded probe directly into tanks, pipelines, and other process components to turn heating equipment on or off at a specified temperature. Set actuation points with the adjustment dial.

Switch with one actuation point has one SPDT (single pole, double throw) relay. The relay can be set to turn one circuit from off to on (normally open) or from on to off (normally closed).

Switch with two actuation points has two SPDT (single pole, double throw) relays. Each relay can be set to turn one circuit from off to on (normally open) or from on to off (normally closed).

Turn heating equipment on or off in environments with flammable gases, combustible dust, and ignitable fibers, such as chemical plants, refineries, and grain elevators. The switch housing is UL listed for use in Class I, Divisions 1 and 2, Groups B, C, and D; Class II, Divisions 1 and 2, Groups E, F, and G; and Class III, Divisions 1 and 2 hazardous locations. It also meets NEMA 4X for use in washdown environments with splashing water, corrosive liquid, and dust. Switches have a probe on a cable for remote temperature readings. Set actuation points with the adjustment dial.

Switch with one actuation point has one SPDT (single pole, double throw) relay. The relay can be set to turn one circuit from off to on (normally open) or from on to off (normally closed). The probe has 1/2 NPT male threads for installation directly into tanks, pipelines, and other process components. It comes with a bushing that adapts the thread size to 3/4 NPT male.

Switch with two actuation points has two SPDT (single pole, double throw) relays. Each relay can be set to turn one circuit from off to on (normally open) or from on to off (normally closed).

Use connectors where ignitable gas and dust may be present, such as in refineries and silos. They are CSA certified for Class I, Division 2, Groups A, B, C, and D; and Class II, Division 2, Groups F and G. All have a chamber that withstands the pressure of an internal ignition—isolating it from spreading to the surrounding environment. They're rated IP66 and IP67 for protection from washdowns and temporary submersion.

Finger drawplates (sold separately) create a grip around plugs and sockets or receptacles, making it easier to pull them together tightly when mating.

Caps (sold separately) protect plugs when not in use.

Simultaneously clean up and neutralize metal powders and other combustible dust, such as coal, plastic, and flour. These vacuums collect combustible dust in a bag, then submerge the bag in a water or mineral oil bath. This makes the dust inert. Because some metal powders emit gas when added to an immersion bath, the vacuums also have a degassing valve to vent any gas that builds up.

The vacuum and tools dissipate static, so they won’t suddenly discharge electricity that could ignite your powder or nearby gases. The nozzle and crevice tool are small enough to use in compact spaces, such as 3D printer housings.

These vacuums are CSA certified for use in all NEC Class II environments—those where combustible dusts are present under normal operating conditions. In addition, they’re also certified for use in Class I, Divisions 1 and 2, Group D environments, so they can be used in environments where flammable gases, vapors, and liquids with characteristics similar to propane can be found under normal operating conditions.

Collect debris while you sand by connecting these vacuum systems to your air-powered or electric sanders. Their built-in manifold has one input and two outputs for compressed air, so one of these systems can take debris from two sanders. Automatically switching on and off when your sander does, they minimize energy costs, wasted time, and noise. All are static-dissipative, so they reduce the risk of sparking, which is a concern when you’re creating flammable debris. They also come with a HEPA-rated filter cartridge that keeps them from circulating the debris they gather. These filters remove at least 99.95% of particles that are 0.3 microns or larger.

To connect them to your sander, add a vacuum hose with integrated air line. The air line connects to the sander’s ¼ NPT air inlet and the hose connects to the 1”-dia. vacuum connection. Otherwise, choose air and vacuum hose that matches your sander’s connections.

Vacuum systems with wheels are easy to roll between sanding stations and into storage.

Use vacuum hose kits to manually clean your workspace, unattached from the sander.

Safe for use around hazardous gasses and dust, these vents maintain steady pressure and prevent moisture buildup from temperature changes inside enclosures. They allow air to flow through the enclosures while protecting the contents from washdowns, dirt, and weather. Install these vents at the lowest point on an enclosure, so moisture can drip out.

Flameproof drains reduce the risk of igniting flammable gasses and dust if an explosion occurs within the enclosure.

316 stainless steel drains stand up to corrosion. They’re best for areas with salt water.
