[Widely Usedl] - This Recessed Door Contact Sensor works with any access control or burglar alarm system available

[Normally Closed] - N.C. means Normally Closed: When the magnet together, the circuit is conductive( light on ); when the magnet separates, the circuit is not conductive ( light off ).

[Note] - the Magnetic Door Switch must be installed according to the sensing distance. It can only provide a switch signal to the transmitter. It cannot directly load the power, nor directly connect the lamp!

Product Information: Product name: Surface-mounted Magnetic Door Switch, Type: MC-31, Color: White, Material: Plastic

Specification: Contact Type: NC, Hole Dia.: 5.8mm, Actuation Distance: 8mm±18mm

This is a small device called a reed switch. When the device is exposed to a magnetic field, the two ferrous materials inside the switch pull together and the switch closes.

When the magnetic field is removed, the reeds separate and the switch opens. This makes for a great non-contact switch
