Coded Magnet for Style B |
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.
