Magnetic Reed Switch NC NO COM Surface Mount MC-31 5pcs by VictorsHome

Description

Product Overview

The VictorsHome Magnetic Reed Switch MC-31 is engineered for precision and reliability in demanding security applications. Constructed from ABS flame‑retardant material, the housing protects the internal reed element from high temperatures and mechanical stress, ensuring long‑term performance. The switch offers three configurable contact types—normally closed (NC), normally open (NO), and common (COM)—allowing installers to tailor the circuit to specific alarm logic without additional components. With a compact surface‑mount footprint, the device integrates seamlessly onto printed circuit boards, saving valuable space in crowded control panels.

Technical specifications highlight a load current capacity of 150 mA and a maximum voltage rating of 100 V DC, making the switch suitable for low‑power alarm circuits and access control systems. The actuation distance ranges from 10 mm to 26 mm, providing flexible mounting options on both wooden and aluminum alloy doors and windows. Each unit includes a detachable cover that enhances aesthetic integration while protecting the contacts from dust and moisture.

Designed for ease of installation, the MC‑31 comes in a 5‑piece pack, each unit pre‑wired with standard 2.54 mm pitch pins compatible with common prototyping boards. The clear labeling of NC, NO, and COM terminals reduces wiring errors and accelerates deployment in both new installations and retrofits. The product’s best‑seller rank in the Reed Switch category reflects its popularity among professional installers seeking dependable performance at an affordable price point.

Beyond its core functionality, the switch’s robust construction meets industry standards for industrial electrical components, offering resistance to vibration and shock. This durability ensures consistent operation in environments ranging from residential homes to commercial facilities, where reliable detection of door or window status is critical for security and safety compliance.

Usage

Ideal for home security systems, the MC‑31 can be mounted on entry doors, sliding windows, and garage doors to monitor opening and closing events. When the magnetic field is disrupted, the reed element toggles the selected contact, triggering an alarm or sending a notification to a central monitoring station. Its fast response time and accurate detection make it suitable for burglar alarm panels, fire alarm integration, and smart home automation platforms that require real‑time status updates.

In commercial settings, the switch serves as a reliable component for access control systems, where it can be paired with card readers or biometric scanners to verify door integrity. The ability to choose between NC, NO, or COM contacts enables flexible wiring schemes, allowing the same hardware to support multiple security zones without additional inventory. Installation on metal doors benefits from the switch’s magnetic actuation distance, which accommodates varying frame thicknesses.

For industrial applications, the MC‑31’s ABS housing provides resistance to harsh chemicals and temperature fluctuations, making it a viable option for equipment enclosures, control cabinets, and safety interlocks. The detachable cover simplifies maintenance, allowing technicians to inspect and replace the reed element without disturbing the surrounding circuitry.

When integrated into DIY projects, hobbyists can leverage the switch’s surface‑mount design to create compact sensor arrays for robotics, IoT devices, and educational kits. The low power consumption aligns with battery‑operated designs, extending operational life while delivering dependable status feedback.

FAQ

What is the difference between NC, NO, and COM contacts?

NC (normally closed) means the circuit is closed when the magnet is present; NO (normally open) means the circuit opens when the magnet is present; COM (common) is a shared terminal that can be linked to either NC or NO depending on wiring needs.

Can the switch be used on metal doors?

Yes, the MC‑31’s magnetic actuation distance of up to 26 mm allows it to function reliably on metal doors and frames, provided the magnet is positioned within the specified range.

Is the ABS housing suitable for outdoor installations?

The ABS material offers resistance to moisture and moderate temperature variations, making it suitable for sheltered outdoor applications such as garage doors and patio windows. For extreme weather conditions, additional protective enclosures are recommended.

How many switches come in one package?

Each SKU includes a pack of five individual magnetic reed switches, allowing for multiple installation points or spare parts without the need for separate orders.

What is the maximum load the switch can handle?

The switch is rated for a maximum load current of 150 mA and a voltage of up to 100 V DC, which is ideal for low‑power alarm circuits and typical security system inputs.
