MC6 NO/NC Magnetic Contact Security Series | Professional Surface-Mount Door & Window Sensor 🛡️🚪

The MC6 Magnetic Security Series provides a versatile and highly reliable solution for residential and commercial alarm systems. Featuring both Normally Open (NO) and Normally Closed (NC) terminal configurations, these surface-mount sensors are designed to integrate seamlessly with various security control panels to monitor the status of doors, windows, and entry points.

Key Product Features

• Dual Output Configuration (NO/NC): Equipped with three screw terminals—Common (COM), Normally Closed (NC), and Normally Open (NO)—allowing for maximum compatibility with different alarm circuit logic.

• High-Strength Magnetic Actuation: Utilizes a precision-aligned internal reed switch that triggers instantly when the corresponding magnetic bar is moved away from the sensor unit.

• Easy-Access Screw Terminals: Features exposed, heavy-duty screw terminals for fast and secure wire termination, eliminating the need for complex soldering or specialized tools.

• Durable ABS Housing: Encased in a rugged, flame-retardant white plastic shell designed to blend into standard door and window frames while providing long-term environmental protection.

• Secure Surface Mounting: Built with integrated mounting flanges on both the sensor and the magnet, allowing for firm installation using standard wood or metal screws.

• "GUARD" Series Branding: Part of the professional-grade Guard series, ensuring consistent performance for high-reliability security monitoring.

Technical Specifications

• Model Series: MC6 Magnetic Security Series.

• Switch Logic: SPDT (Single Pole Double Throw) with COM, NO, and NC terminals.

• Mounting Style: Surface Mount.

• Material: High-Impact ABS Plastic.

• Color: Classic Security White.

• Application: Perimeter security, access control systems, and automated lighting triggers.

Top 3 Customer Questions & Concerns 🙋‍♂️

⚙️ What is the difference between the NO and NC terminals? The Normally Closed (NC) terminal is used for standard "closed-loop" alarm systems where the circuit is broken (triggering the alarm) when the door opens. The Normally Open (NO) terminal is used for "open-loop" systems or specialized triggers where you want the circuit to complete (activating a light or chime) only when the door is opened.

🔌 Do I need a power supply for the sensor itself? No, these are passive magnetic switches. They do not require a dedicated power source; they simply act as a physical bridge for the low-voltage current provided by your alarm control panel.

⚠️ How far apart can the magnet and sensor be? For reliable operation, the magnet and sensor should be mounted as close as possible when the door or window is closed (typically within 15mm to 20mm). If the gap is too large, the internal reed switch may not engage properly, leading to false alarms.
