Product information

Description

KN-CA55L is a wired door contact sensor by No name, a surface-mount magnetic reed switch designed to detect the open or closed state of doors and windows. The sensor consists of a contact unit and a magnet, providing a reliable binary signal for alarm panels and access control systems in both residential and commercial installations. Its compact surface-mounted design simplifies installation where recessed mounting is not practical.

Advantages

The KN-CA55L offers straightforward wired connectivity and a simple magnetic reed mechanism that yields a clear open/closed signal without the need for batteries. Its surface-mount format reduces installation complexity and allows use on a wide range of door and window frames. The paired contact and magnet arrangement ensures durable operation for perimeter intrusion detection and status monitoring when integrated with standard alarm or access control equipment.

Suitable for

  • Perimeter intrusion detection on doors and windows
  • Status monitoring for alarm panels and security systems
  • Access control door state sensing
  • Residential and small commercial security installations

Key specifications

  • Type: Wired magnetic reed switch (surface-mount)
  • Configuration: Two-part sensor — contact unit and magnet
  • Output: Binary open/closed contact signal compatible with alarm panels and access control inputs
  • Mounting: Surface mounting suitable for doors and windows
  • Application: Perimeter detection and door/window status monitoring

How to use

Mount the contact unit on the fixed frame and the magnet on the moving part of the door or window so that they align when the door/window is closed. Connect the sensor wires to the corresponding input on the alarm panel or access control unit following the control system manufacturer’s wiring diagram. Verify alignment and operation by opening and closing the door or window while observing the controller’s status indicator or input monitoring. Ensure wire routing and connections are secure and protected from mechanical damage.

Usage recommendations

Place the sensor pair where the contact and magnet can align closely when closed and maintain at least the recommended gap specified by the control system documentation. For reliable long-term operation, avoid mounting on surfaces subject to heavy impact or frequent moisture exposure, and secure wiring to prevent strain or cuts.
