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.
