Door/Gate Contact Sensor GENWAY KONTAKTRON KN-CA61-V2 - Magnetic reed switch, NO

GENWAY KONTAKTRON KN-CA61-V2 is a magnetic door and gate contact sensor that uses a normally open reed switch to detect the open or closed state of a door, gate or window. Designed for wired connection to alarm panels, access control units and building automation systems, this compact sensor is mounted with the magnet aligned to the contact body so the circuit closes when the moving element is brought into position. The device is intended for perimeter monitoring, entry detection and reliable status reporting in security and automation installations.

Advantages

The GENWAY KONTAKTRON KN-CA61-V2 offers a simple normally open contact that is easy to integrate with a wide range of control panels and automation controllers. Its magnetic reed mechanism provides mechanical reliability with low power consumption and minimal maintenance. The compact form factor allows mounting on frames and moving leaves with straightforward alignment, and the wired interface ensures consistent, interference-free signal transmission for critical security inputs.

Suitable for

• Perimeter doors and gates monitoring
• Entry and exit detection for access control systems
• Integration with wired alarm panels and security systems
• Home and building automation status inputs

Key specifications

• Switch type: magnetic reed, normally open (NO)
• Connection: wired contact output for direct input to control panels
• Mounting: surface mounting on frame and moving leaf
• Operating principle: magnet-actuated contact closure
• Application environment: doors, gates, windows and similar moving closures

How to use

Mount the contact body on the fixed frame and the magnet on the moving leaf so that the two parts align when the door or gate is closed. Connect the sensorwires to the alarm panel or controller input configured for a normally open contact. Verify alignment and operation by closing and opening the door while observing the control panel input status. Secure cabling and use appropriate conduit or cable ties to protect the wiring in exposed installations.

Usage recommendations

For reliable operation, position the magnet and contact within the manufacturers recommended gap tolerance, avoid placing strong external magnets nearby, and protect wiring from moisture and mechanical damage. Test the sensor after installation and during regular maintenance checks as part of the overall security or automation system.
