Wired Rolling Door Contact Magnetic Switch for Home Security

Package Content: - 1 x Sensor Switch - 1 x Magnetic - 4 x Screw Type (Normally Closed)

Before placing an order, please be aware that our door reed switches are normally closed (NC). This means that when the magnet is together, the circuit is conductive (light on), and when the magnet separates, the circuit is not conductive (light off).

Installation Instructions for Door Magnets: The door and window magnets should be installed at the door and the top of the window, with the permanent magnet part installed on the movable door and window, and the switch part installed on the fixed door and window frame. It is important to align and install the switch part and the magnet part as accurately as possible to avoid any deviation from the best conduction area of the magnetic field line and the reed switch contact, which may shorten the sensing distance or cause the switch to malfunction. It is recommended to position the pen before drilling to avoid severe misplacement during installation. Additionally, the door magnet should be placed away from any sources of magnetic field interference, such as transformers, as this could change the working characteristics of the door magnet and lead to possible wrong actions.

[Specification] - Current: 0.5A - Voltage: 0-100V - Power Rating: 10W - Action Distance: 50~70mm

[N.C.] When the magnet is together, the circuit is conductive (light on); when the magnet separates, the circuit is not conductive (light off). Please double check when placing an order!

[Applications] The Rolling Door Contact is designed for use with window and door alarm systems, such as garage, industrial warehouses, and shops.

[Material] The magnetic switch alarm is made with durable zinc alloy housing for better rust resistance.
