## Summary description

KN-CA38B is a side-mount magnetic reed switch (kontaktron) manufactured under No name brand. The device is a simple magnetic contact sensor used for detecting door or window position in security and alarm systems. It provides on/off contact switching when a magnetic field from a mating magnet is present, suitable for basic intrusion detection and position monitoring.

## Long description

KN-CA38B is a side-mount magnetic reed switch (kontaktron) produced under the No name brand. This compact sensor provides a simple normally-open/normally-closed contact that changes state when a magnetic field from a mating magnet is nearby. Designed for flush or surface installation at the side of doors, windows or frames, the KN-CA38B is intended for basic position detection and intrusion sensing in alarm and access-control systems.
Advantages
The KN-CA38B offers a small side-mount form factor that fits narrow installation spaces. Its passive reed contact requires no power to detect a magnet, enabling low-maintenance operation and long service life. The device is mechanically simple and compatible with common alarm control panels and wired input circuits, providing reliable on/off signaling for basic security and monitoring applications.
Suitable for
 Door and window position detection in residential and commercial alarm systems
 Basic intrusion or tamper monitoring for cabinets, gates, and shutters
 Integration with wired security panels, DIY alarm kits, and relay inputs
 Applications requiring a compact side-mounted magnetic contact sensor
Key specifications
 Mounting type: side-mount for narrow profiles and frame edges
 Contact type: magnetic reed contact providing on/off switching
 Operating principle: magnet-actuated reed switch (passive device)
 Typical applications: door/window position and basic intrusion detection
 Construction: compact housing suitable for concealed or surface placement
How to use
Mount the sensor body on the fixed frame or sash edge so that the mating magnet aligns with the reed contact when the door or window is closed. Connect the reed switch leads to the alarm panel or input circuit following the panel manufacturer's wiring diagram for normally-open or normally-closed contacts as required. Adjust the magnet position and sensor placement to ensure reliable operation and to achieve the intended switching distance. Test the switch by opening and closing the door or window and verifying the input state on the connected control device.
Usage recommendations
Use a compatible magnet sized and positioned to match the KN-CA38B switching gap; avoid installing the sensor near strong external magnetic sources. For reliable long-term operation, secure wiring to prevent mechanical strain and protect the sensor from direct moisture and excessive impact. When integrating with alarm systems, observe the control panel's input specifications and, if needed, add end-of-line resistors or tamper loops according to the system design.
