These switches actuate when a magnet comes within sensing distance, and reset when the magnet moves away. They’re often used to detect when a door or window opens. Mount the switch in a stationary position, such as a door frame, and mount the magnet to a movable object, such as the door. They do not include a safety relay and cannot be used with safety-guard doors found on machinery.
M8 Connection and M12 Connection—Switches with a M12 or M8 plug connect to cords with a socket (sold separately), allowing you to quickly connect and disconnect the switch.
LED Status Indicator—Switches with an LED status indicator let you visually confirm that it’s connected and whether it’s actuated.
IP65 Enclosure Rating—IP65 rated switches protect against rinsing and dust.
IP67 Enclosure Rating—IP67 rated switches protect against temporary submersion, as well as dust and dirt.
IP68 Enclosure Rating—IP68 rated switches protect against washdowns and continuous submersion.
IP69K Enclosure Rating—Use IP69K rated switches in demanding environments, such as roadways.
