Magnetically Actuated Switches
A
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.
NEMA 4X rated switches are protected from corrosion and washdowns. These switches are also rated IP67 for protection from temporary submersion.
