MC38 Wired Door Window Sensor N.C Type, Reliable Magnetic Switch Detection for Home Security

MC38 Wired Door Window Sensor 1 set Quick overview A wired magnetic switch sensor for door and window monitoring. Model MC38 delivers a simple normally closed contact that connects to compatible wired alarm systems for reliable open and close detection. Key benefits Reliable wired connection for consistent alarm input to your control panel. Magnetic switch provides clear open and closed signals for accurate detection. N.C type (normally closed) operation works with most alarm systems that expect a closed circuit when doors or windows are shut. Compact set that installs where you need discreet perimeter sensing without wireless interference. 330 mm wire length (lengthen randomly) for flexible placement relative to the alarm panel. What it does and why you need it Detects when a door or window is opened by sensing separation between the magnet and the switch. When the circuit opens, your alarm panel receives the signal to trigger an alert according to its configuration. Ideal when a wired solution is preferred for stable connectivity and predictable behavior in home and small business security setups. Useful for replacing or adding sensors to existing wired alarm systems that require a normally closed contact type. Important attributes Model: MC38 Type: Wired door and window magnetic switch Contact type: N.C type (normally closed) Wire length: 330 mm (lengthen randomly) Quantity: 1 set Compatibility and installation notes Compatible with wired alarm panels and input modules that accept normally closed magnetic switches. Simple signal interface makes it suitable for integration with alarm control panels, alarm input zones, and monitoring modules that expect a door or window contact. Use where a wired sensor is preferred or required by the security system design. Practical use scenarios Home entry monitoring: Install on a front or back door to provide a reliable wired contact to a home alarm panel. Window protection: Mount on sliding or casement windows to detect unauthorized opening and feed the signal to a wired alarm zone. Garage or storage access: Use on garage doors, storage room doors, or cabinets connected to a wired security system to monitor access points. What to expect A straightforward magnetic switch that provides a normally closed contact for wired alarm inputs. Confirm compatibility with your alarm system configuration before installation to ensure correct zone wiring and response behavior.
