Reed Switch (Side) KONTAKTRON KN-CA44B*P10 — NO NAME, model KN-CA44B*P10

The Reed Switch (Side) KONTAKTRON KN-CA44B*P10 is a side-mounted magnetic contact sensor designed to detect open and closed states when used with a permanent magnet. Its compact lateral activation design makes it suitable for installation in narrow profiles, door and window frames, and other locations where end-mounted sensors are impractical. The sensor provides a simple normally-open (NO) switching function and is intended for use in alarm systems, access control, and other security or monitoring circuits.

Advantages

This side-mounted reed switch offers a compact footprint and lateral activation, allowing installation in tight frame profiles and narrow mounting spaces. The normally-open contact arrangement simplifies wiring for systems that require a closed circuit only when a magnet is present. Its mechanical simplicity ensures low power consumption and long service life when used within specified operating conditions. The device is compatible with common alarm and monitoring equipment and can be integrated into existing security installations where side activation is preferred.

Suitable for

• Door and window magnetic contacts in security systems
• Access control sensing for frames and sliding profiles
• Email and alarm zones requiring side-mounted sensors
• Retrofit installations with limited mounting depth

Key specifications

• Switch type: Normally-open (NO) reed contact
• Mounting orientation: Side/lateral activation
• Form factor: Compact profile suitable for narrow frames
• Operating principle: Magnetic actuation with permanent magnet
• Intended use: Security and alarm system sensing

How to use

Install the reed switch in the frame or profile so that the magnet on the moving part aligns laterally with the sensor when the door or window is closed. Secure the sensor using appropriate fasteners or adhesive compatible with the mounting surface, ensuring stable positioning and correct gap distance to the magnet. Connect the sensor leads to the alarm panel or monitoring device following the panel manufacturer's wiring instructions for normally-open contacts. Test operation by moving the magnet into and out of alignment to verify that the circuit closes and opens as expected.

Usage recommendations

Place the sensor and magnet with minimal lateral gap while avoiding direct mechanical contact. Verify compatibility with the alarm or control panel and respect environmental limits such as temperature and humidity. For reliable long-term performance, avoid exposing the sensor to strong mechanical shocks or corrosive environments and perform periodic functional tests as part of routine maintenance.
