## Long description

Kontaktron bramowy KN-OC55 magnetic door contact sensor, model KN-OC55 is a magnetic contact switch designed to detect open and closed states of doors, gates or panels. The sensor uses a magnetic reed mechanism to provide a reliable binary signal for alarm systems, access control units and security monitoring devices. Its compact form factor allows installation on typical door and gate frames where basic, passive state detection is required.
Advantages
The magnetic contact sensor offers a simple and robust switching principle that does not require complex electronics at the sensing point, ensuring compatibility with a wide range of alarm panels and controllers. Its compact design supports installation in limited spaces and on different types of frames. The sensor provides clear open/closed state information and is suitable for long-term passive operation with minimal maintenance.

Key specifications
 Type: magnetic reed/contact door/gate sensor
 Function: detects open and closed states of panels
 Interface: passive magnetic contact output suitable for alarm inputs
 Form factor: compact sensor and magnet pair for frame mounting
 Application environment: indoor and sheltered outdoor mounting on doors and gates
How to use
Mount the sensor body on the fixed frame and align the magnet on the moving leaf so that the two parts are adjacent when the door or gate is closed. Connect the sensor leads to the alarm panel or controller input that accepts a normally open or normally closed reed contact, following the control panel wiring guidelines. Ensure correct alignment and secure fastening to prevent movement; test the sensor by opening and closing the door to confirm the input state changes correspondingly.
Usage recommendations
For reliable performance, install the sensor in a sheltered location or use appropriate sealing if exposed to weather. Regularly check mounting integrity and wiring connections. Avoid placing strong external magnets or ferromagnetic objects nearby that could affect the reed switch operation.
