    Connection

    When a moving object contacts the actuator on these switches, they open or close a circuit. They have the rapid-closing action of a snap-acting switch, but with a larger actuator. This makes them a good choice for use with large objects—for instance, a box on a conveyor runs into the switch, stopping the conveyor.
    Plunger Actuator—Switches with a plunger actuator require a push to actuate, similar to a button.
    Roller Plunger Actuator—Switches with a roller plunger actuator have a roller that moves when an object pushes the actuator. This reduces friction during actuation to limit wear and tear on your switch.
    Roller Lever Actuator—Switches with a roller lever actuator use a lever with a roller at the end to activate. This allows parts to glide across the actuation surface with minimal friction, limiting wear and tear on your switch.
    4-Pole M12 Connection—Switches with a 4-pole M12 plug connect to cords with a socket (sold separately), allowing you to quickly connect and disconnect the switch.
    Style E—Styles E and F let you adjust the actuator’s height to align it with your target.
    IP67 Enclosure Rating—Switches rated IP67 are protected against dust and temporary submersion.

    Build-Your-Own Limit Switches

    Combine an actuator and a switch to assemble the exact limit switch you need. These switches have the rapid-closing action of a snap-acting switch, but have a larger actuator for large objects. When an object in motion comes into contact with the actuator, it sends a signal to open or close a circuit. They’re often used for conveyor systems and elevators. Each actuator style is compatible with all housing styles and vice versa.

    Polypropylene Housing—Switches with a polypropylene housing are lighter in weight than metal switches.
    Zinc Housing—Switches with a zinc alloy housing are more durable than those with a plastic housing.
    LED Power Indicator and LED Status Indicator—Switches with an LED power indicator and LED status indicator show you the status of the line and load phases. They give you extra assurance that your switch is connected and wired correctly.
    4-Pole M12 Connection—Switches with a 4-pole M12 plug quickly connect and disconnect from your setup. Use cords (sold separately) to wire your switch connection to your setup.
    2 Conduit Connections—Switches with 2 conduit connections allow you to wire switches side by side, so you can save space and simplify your wiring.
    IP65 Enclosure Rating—IP65 switches protect against dust and splashing water.
    IP66 Enclosure Rating—IP66 switches protect against dust and washdowns.
    IP67 Enclosure Rating—IP67 switches protect against dust and temporary submersion.
