MC-38 Magnetic Reed Switch For Door Windows

The MC-38 Magnetic Reed Switch For Door Windows is a compact, low-profile magnetic sensor designed to detect the relative position of a door or window and trigger a contact closure when the magnet is moved away or returned. Its simple two-part construction—reed switch and matching magnet—provides a reliable, passive sensing solution suitable for security systems, alarm panels, access control, and basic open/closed status monitoring.Engineered for straightforward installation, the MC-38 can be mounted on most door and window frames where discreet, tamper-resistant sensing is required. The unit is compatible with standard wiring and mounting practices used in residential and commercial security installations. Because it operates using magnetically actuated reed contacts, the device consumes negligible power while idle and does not require a local power source to sense changes in position.The MC-38 offers a durable contact mechanism enclosed in a protective housing to reduce exposure to dust and incidental contact. Its compact form factor accommodates tight mounting spaces and helps maintain a low visual profile when installed. Installers will find the component straightforward to align with the accompanying magnet for consistent operation, and it integrates cleanly with conventional alarm inputs and monitoring circuits.Typical applications include perimeter protection for doors and windows, monitoring of cabinets or panels, and use wherever a reliable, passive open/closed sensing element is needed.
