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.
Switches with a polypropylene plastic housing are lighter in weight than metal switches. Switches with a zinc housing are more durable than those with a plastic housing.
Switches with a 4-pole micro M12 plug quickly connect and disconnect from your setup. Use cables (sold separately) to wire your switch connection to your setup.
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.
IP66 switches protect against dust and washdowns. IP67 switches protect against dust and temporary submersion.
