Description
Product Overview
The Sopepoyie NC/NO wired door contact sensor is engineered to provide a robust magnetic reed switching solution for a wide range of security applications. Constructed from high‑quality copper contacts housed in a durable black polymer shell, each unit offers a compact footprint of 55 × 12.5 × 11.5 mm, making it ideal for discreet installation on doors, windows, cabinets, and other access points. Rated for 100 V operation and a maximum contact capacity of 500 mA, the sensor delivers reliable performance even in demanding environments. The NC (normally closed) and NO (normally open) contact configurations allow flexible integration with alarm panels, LED indicators, relays, and low‑voltage GPS devices, ensuring seamless compatibility with existing security infrastructures. With a lightweight design of just 0.09 kg per unit, the sensor is easy to handle and install, reducing labor time and simplifying system upgrades.
Usage
Designed for both residential and commercial settings, this sensor excels in applications where reliable door status monitoring is critical. In a home security system, the sensor can be paired with a central alarm unit to trigger audible alerts or push notifications when a door is opened or closed, enhancing occupant safety and deterring unauthorized entry. In office environments, the sensor integrates smoothly with access control panels to log entry events, support automated lighting control, or activate HVAC adjustments based on occupancy. The wired connectivity eliminates the need for battery replacements, providing a maintenance‑free solution that operates continuously. Installation is straightforward: the sensor mounts on a wall or frame using the provided screws, and the magnetic reed is positioned on the moving part of the door or window, creating a trigger gap of 15‑20 mm. This simple setup enables rapid deployment across multiple entry points, making it an excellent choice for multi‑door installations, such as apartment complexes, retail storefronts, and industrial facilities.

FAQ
What is the difference between NC and NO contacts?
NC (normally closed) contacts remain connected until the magnetic field is disrupted, while NO (normally open) contacts stay disconnected until the field is broken. This allows you to choose the behavior that best fits your alarm or control system.
Can the sensor be used with battery‑powered devices?
The sensor itself does not require batteries because it is wired, but it can be integrated into battery‑powered alarm panels or relay modules that supply the necessary voltage.
What is the recommended mounting surface?
The sensor is designed for wall or frame mounting on metal, wood, or plastic surfaces. Ensure the magnetic counterpart aligns within the 15‑20 mm trigger range for optimal performance.
Is the sensor compatible with smart home systems?
Yes, the sensor can be connected to smart home hubs that accept wired reed switch inputs, allowing you to create automation rules such as turning lights on when a door opens.
How many sensors can I connect to a single alarm panel?
Multiple sensors can be wired in parallel to a single alarm panel, provided the total current draw does not exceed the panel’s specifications. Each sensor draws minimal current, making it suitable for large installations.
