Model: MC38B Wired Door Window Sensor (Magnetic Alarm) Key characteristics: N/c N/o switch, threewire, 100V DC, normally closed/opened, 2025, reliable electronic component, precision, stable performance. Why you need the MC38B Reliable intrusion detection: The MC38B is a wired magnetic door/window sensor that immediately notifies your alarm system when a protected point opens or closes. Flexible wiring options: The threewire design provides both normally closed (NC) and normally opened (NO) switching options so you can match the sensor to a wide range of alarm panels and configurations. Built for stable, longterm use: Marketed as a reliable electronic component with precision and stable performance, the MC38B is intended for security installations where consistent operation matters. Key benefits (how it solves problems) Reduces false alarms: Precision switching minimizes inadvertent triggers so your system responds only when intended. Simple integration: Wired connection and NC/NO options allow straightforward wiring into wired alarm systems that accept up to 100V DC. Versatile deployment: Use the same sensor model across multiple points in a property without reordering for different contact types. Features and attributes Functionality: Magnetic reed switch for door/window monitoring; provides both normally closed and normally opened signaling through a threewire interface. Compatibility: Designed for wired alarm systems and electronic devices that accept a 100V DC input and support NC/NO contacts. Electrical rating: Rated for 100V DC operation (as specified). Wiring: Threewire configuration supports flexible installation and choice of NC or NO operation. Performance: Described as precision and stable performance with reliability (model MC38B, 2025). Installation and use notes Intended to be installed as a wired sensor on doors, windows, safes and similar enclosures. Choose NC or NO wiring according to your alarm panel requirements. Ensure the host system supports 100V DC and the sensor wiring configuration before installation. Typical applications Home security: Monitor doors and windows to trigger alarms or notifications when protected entry points open. Safe and cabinet protection: Use on home safes, lockers or cabinets to detect unauthorized opening and secure valuable items. Small commercial or utility rooms: Protect server closets, storage rooms or access panels where a reliable, wired contact is required.
