  • What's Included
  • The most basic sensor of any alarm system is a door and window Surface Mount Magnetic Contact Switch. This type of contact switch is for normally closed (N/C) circuits meaning that when the magnets are lined up, the switch is closed. This type of setup is ideal for monitoring doors, windows, and sliding doors. Measuring 2.48 inches long and 1/2 inch high, the contacts attach with wood or sheet metal screws (not included) to the frame of the door or window, and the case or jam.

    A Normally Open Surface Mount Magnetic Contact Switch is also available individually and in a 10-Pack.

    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&degF and 160&degF. The sensor's maximum operational gap is 3/4 inches. Mount the magnet on the door or window so that the two are in contact with each other when the door or window is closed. Slotted mounting holes make it easy to adjust the distance between the magnet and the sensor.

    These are, by far, the best sensors available. they are heavier than the ones provided by the alarm maker. and at a more than reasonable price!

    I ordered normally closed switches, figuring that the magnet would open them when the door is closed. Should have ordered NO I guess, confusion on this end, looks like.
    The switches are good.

    Put these in a couple of my stores door security alarms and they seem to be working fine now. Only been in about 2 weeks but it was what I thought it would be.

    Review of 7113

    I purchased these to go with the INSTEON contact closure interface to monitor and control my garage doors. There is no mounting hardware or brackets included with these units, but I knew that from the get-go. I fabricated my own brackets to mount on the top of the garage door out of plexiglas purchased at the Home Depot and cut down and made into a right angled bracket (formed with a heat gun) for the magnet. On my doors the sensor had to be mounted about 3" above the door when closed in order for the door to clear the sensor while the door opened and moved away from the door frame. The fabricated bracket attached to the top of the door such that it was within an inch of the sensor with the door closed. That works fine. Since I have 3 bays, I also had to add a 3 outlet box to accommodate the 3 contact closure interfaces. You need lots of #20-22 gauge dual conductor wire for connections, but I was able to locate that in a local surplus store very cheaply.
