Hazardous Location Limit Switches

Plunger Actuator | Wobble Stick Actuator |
Safely open or close a circuit near ignitable gases and dust—the housing on these switches seals in anything that could ignite flammable material. You'll know they're safe because they're NEC Class I, Divisions 1, 2 Groups B, C, and D; and Class II, Divisions 1, 2 Groups E, F, and G certified for hazardous locations. These switches send a signal to your circuit when an object hits the actuator—for instance, a box on a conveyor runs into the switch, stopping the conveyor. They open and close circuits as fast as snap-acting switches, but they have a bigger actuator for large objects.
Plunger Actuator—Switches with a plunger actuator let you adjust the actuator’s height to easily align it with your target. They require a push to activate, similar to a button.
Wobble Stick Actuator—Switches with a wobble stick actuator have an arm that rotates 360°, so you don’t need to align it in a specific direction. The actuator won’t snap if pushed backward, such as if there’s a jam in your system.

Speed-Monitoring Switches
 |  |
Detect unwanted slowdowns in a rotary shaft that could cause machine damage and downtime. These switches are often used on drivetrains, conveyors, and other power-driven components. They come with a pulser disc, which you’ll need to attach to the shaft by drilling and tapping a hole. Once mounted, the disc rotates with the shaft and creates magnetic signals that the switch senses. When the speed falls below a set point, the switch will trigger an alarm or turn off the system.
Switches are UL listed and rated NEC 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.

Hazardous Location Rotatable DC Metallic-Object Proximity Sensors

 |  |
4-Pole M12 Plug | Flush Mount |

Projecting Mount |
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 sensors are UL and C-UL listed as well as ATEX and IECEx certified for hazardous locations. Their NAMUR signal produces low current and low voltage, so they won’t spark or ignite. You must connect them to a barrier (sold separately), which reduces the current and voltage that enters your hazardous area.
Because you can rotate the sensor, these make good replacements for limit switches with actuators that could break when hit. They’re often known as inductive proximity sensors and detect objects even if they’re covered by water, oil, dirt, or a surface finish. Sensing distance is based on the type of material that’s sensed; the distance listed is for mild steel. Send signals from these sensors to programmable logic controllers (PLCs) to support automated processes.
These sensors have a 4-pole M12 plug that connects to cables with a socket (sold separately), so you can quickly connect and disconnect them. You can also check on them from any angle, thanks to LED status indicators on their corners. All are CE marked for safety.

IP rated, all sensors seal out dust and water from high-pressure washdowns.
IP67 Enclosure Rating and IP68 Enclosure Rating—IP67- and IP68-rated sensors withstand some submersion.
Flush Mount—Flush sensors, also called embeddable and shielded sensors, are more accurate than projecting sensors at close range. They also won’t interfere with each other’s signals when installed close together. Their sensor face mounts evenly with any material, including metal.
Projecting Mount—Projecting sensors, also known as non-embeddable and unshielded sensors, sense objects farther away than flush sensors. But, the area around the sensor must be metal free.
