VictorsHome Magnetic Reed Switch NO 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/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: NOMaximum 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 (LWH)Each Wire Length(Approx.): 30cm / 11.8inchWire Type: 1007/24320mmULHousing Material: ABSPackage Content: 5pcs x Magnetic Door Switch20pcs x Mounting Screws
Product Features
- MATERIAL - The switch housing is made of ABS flame retardant material and the reed switch is resistant to high temperature and deformation.
- NORMALLY OPEN(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).
- 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 cannot exceed 150mA.
- WIDE APPLICATIONS - Work with all access control and burglar alarm systems. Can be installed in wooden or aluminum alloy doors and windows.
