  • What's Included
  • The SECO-LARM Enforcer SM-300Q/WH Surface Mount Magnetic Contact Switch is ideal for any normally open location and sends an alert signal to your security system when it is no longer in a normally open state. Simply mount the magnetic sensors on a door or window so that the two are in contact with each other when the door or window is closed. Breaking the connection between the two sensors triggers an alert thus notifying your property's security system. Slotted mounting holes make it easy to adjust the distance between the magnet and the sensor, with a maximum operational gap of 0.75 inches. Measuring 2.48 inches long and half an inch high, they can be attached with wood or sheet metal screws, sold separately. The switch is waterproof and mounted in a high-impact plastic case. The rhodium plated contacts handle up to 100mA at 100 volts DC and are rated for 50 million openings and closings. It can reliably operate in temperatures between -15°F and 160°F. The sensor's maximum operational gap is 0.75 inches.

    Works great with the IOLinc module for detecting when a garage door is open. (Avoids having to reprogram the IOLinc to reverse its on/off conventions, which can have unexpected side effects.)

    The part works great. It did take a while to get it because it was backordered. Our source for this type of part no longer carries this so we appreciate that you have it.

    Perfect! Installed on closet door, to control lights inside closet, kinda like refrigerator light (NYC electrical code doesn't allow regular light switches in closets). Works like a charm, with a controller.

    It's rated for 3/4", but my experience shows it's a bit more sensitive than that. Which is a good thing.

    Note that "normally open" is the opposite of how most other vendors use the term. "Normally" here means "when the magnet is next to the switch", not "when the magnet is far away".
