Perfect for integration with access control and burglar alarm systems, this 5-pack sensor set offers reliable, fast-response detection to protect your property. ## Description Differences of NC, NO, NC/NONormally Closed(NC): When the switch is close to the magnet, the circuit is conductive(light on); when the switch is separated from the magnet, the circuit is not conductive(light off).Normally Opened(NO): When the switch is separated from the magnet, the circuit is conductive(light on); When the switch is close to the magnet, the circuit is not conductive(light off).NC/NO Combined: The switch has 3 contact types: NC/NO/COM, you can choose to connect two of the contacts(NC-COM or NO-COM).PLEASE NOTEA magnetic door contact can only provide a switching signal to the device. It cannot directly load the power supply and cannot be directly connected to the lamp.Specifications:Model: MC-38Contact Type: NC/NO/COMMaximum Sensor Sensitivity: 10-20mmLoad Current: 150mAWithstand Voltage: DC 0-36VWorking Voltage: DC 0-24VMounting Hole Distance: 18mm / 0.71inchSize(Approx.): 27 x 14 x 8mm / 1.06 x 0.55 x 0.31inch (L*W*H)Each Wire Length(Approx.): 30cm / 11.8inchWire Type: 1007#/24#320mmULHousing Material: ABSPackage Content: 5pcs x Magnetic Door Switch20pcs x Mounting Screws ## Features - MATERIAL - The switch housing is made of ABS flame retardant material and the reed switch is resistant to high temperature and deformation. - NORMALLY CLOSED/NORMALLY OPENED - This switch has 3 contact types: NC/NO/COM, you can choose to connect two of the contacts according to your need. - ACTUATION DISTANCE - 10-20mm transmitting distance.
