Magnetic Reed Switch NC Surface Mount Wired Door Window Contact Sensor with Adhesive Paper for Home Security and Burglar Alarm Systems MC-38 5pcs

Differences of NC, NO, NC/NO

Normally Closed(NC): When the switch is with reference to the magnet, the circuit is conductive(light on); when the switch is separated from the magnet, the circuit isn’t conductive(light off).

Normally Opened(NO): When the switch is separated from the magnet, the circuit is conductive(light on); When the switch is with reference to the magnet, the circuit isn’t conductive(light off).

NC/NO Combined: The switch has 3 contact types: NC/NO/COM, you’ll be able to select to connect two of the contacts(NC-COM or NO-COM).

PLEASE NOTE

A magnetic door contact can only provide a switching signal to the device. It can not straight away load the power supply and can’t be straight away connected to the lamp.

MATERIAL – The switch housing is made of ABS flame retardant material and the reed switch is resistant to high temperature and deformation.
NORMALLY CLOSED(NC) – When the switch is with reference to the magnet, the circuit is conductive(light on); when the switch is separated from the magnet, the circuit isn’t conductive(light off).
ACTUATION DISTANCE – 10-20mm transmitting distance. The contact has fast reflection and accurate detection.
WORKING CONDITIONS – When the magnetic door is energized, the voltage is controlled at DC 0V-24V and the load current can not exceed 100mA.
WIDE APPLICATIONS – Work with all get entry to keep watch over and burglar alarm systems. May also be installed in wooden or aluminum alloy doors and windows.
