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.
NEMA 4X Enclosure Rating—NEMA 4X rated switches are protected from corrosion and washdowns.
NEMA 6 Enclosure Rating—NEMA 6 rated switches are protected from temporary submersion.
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.
IP69 Enclosure Rating—IP69 rated switches resist high temperature washdowns and dust.
IP69K Enclosure Rating—Use IP69K rated switches in demanding environments, such as roadways.

Prevent unauthorized use—these switches require coded magnets (sold separately) to actuate, and cannot be bypassed using ordinary magnets. They actuate when a magnet comes within sensing distance, and reset when the magnet moves away. 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’re often used to detect when a door or window opens, and can be used with movable machine guards. All are rated IP67 for protection from temporary submersion.
Safety relays are required in safety applications with switches that control two or three circuits.
LED Status Indicator—Switches with an LED status indicator light up when they’re actuated, so you can see if they’re wired correctly with a quick glance.

Tamper-Resistant Magnetic Contact Alarm Switches
 |  |  |
Flush Mount | Surface Mount | Surface Mount with Conduit Connection |
Prevent unauthorized use of doors or windows with a combination of coded magnets and contacts that wire to an alarm system. The coded magnets mean they can’t be bypassed with regular magnets. These switches actuate when the magnet comes within sensing distance of the switch and reset when the magnet moves away. Mount the magnet to your door or window and the switch to the frame. Connect the switch contacts to an alarm system, which will trigger when the magnet is pulled away as your door or window is opened.
Flush Mount—Flush-mount switches are designed to mount against the door jam. They have a cord grip to reduce strain on your cord.
Surface Mount—Surface-mount switches mount on the surface of your door.
Conduit Trade Size 1/2—Switches with a 1/2 conduit connection are ready to directly attach to your conduit.
