Magnetic Reed Switch MC-32 NC 6-Pack White Gtziqa Surface Mount Sensor

Description

Product Overview

The Gtziqa MC-32 NC magnetic reed switch set is engineered for precise detection of door and window status changes in a wide range of security applications. Each of the six units measures a compact 2.5 x 0.7 x 0.5 inches and weighs just 5.1 ounces, allowing unobtrusive installation on virtually any surface. Constructed from a durable alloy and high‑temperature ABS plastic, the housing resists fire, corrosion, and mechanical wear, ensuring long‑term reliability even in demanding environments.

These switches operate on a normally closed (NC) principle, meaning the circuit remains closed until a magnetic field separates the reed contacts. When a magnet is positioned within the recommended 15–25 mm gap, the contacts open, instantly signaling an intrusion or opening event to the connected alarm system. The NC configuration is compatible with both wired and wireless alarm panels, making the MC-32 an adaptable choice for legacy systems as well as modern smart‑home integrations.

Installation is straightforward thanks to the included mounting hardware and plug‑in connector type. Users simply align the switch with the magnet, secure it with the supplied screws, and connect the leads to the alarm control board. No batteries are required, eliminating maintenance concerns and reducing overall system cost. The white finish blends seamlessly with interior décor while still providing a clear visual cue for installers.

Usage

Designed for versatility, the MC-32 NC reed switches excel in residential, commercial, and industrial settings. Homeowners can protect entry points, garage doors, and even cabinet doors by integrating the sensors into existing alarm zones or adding new wireless zones for expanded coverage. In small businesses, the switches can be deployed on storefront windows, back‑door exits, and inventory cabinets to deter unauthorized access and trigger real‑time alerts.

Because the device is surface‑mount, it can be installed on thin metal, wood, or plastic panels without the need for extensive drilling or modifications. This makes it ideal for retrofit projects where preserving the original structure is essential. The switches also perform reliably in temperature‑controlled environments such as data centers, server rooms, and laboratory spaces, where fire‑resistant ABS housing adds an extra layer of safety.

For smart‑home enthusiasts, the MC-32 can be linked to popular home automation hubs that support wired contact sensors, enabling automated actions like turning on lights, sending push notifications, or activating cameras when a door is opened. The low power consumption and lack of battery requirements mean the sensor can remain active indefinitely, providing peace of mind for long‑term monitoring.

FAQ

What is the recommended gap distance between the switch and the magnet?

The optimal gap is between 15 mm and 25 mm. This range ensures reliable contact opening while maintaining a strong magnetic field for consistent detection.

Can the MC-32 NC switches be used with wireless alarm panels?

Yes. Although the switches are wired, they can be added to a wireless panel as a hard‑wired contact sensor, allowing you to expand existing wireless zones without replacing the entire system.

Do these switches require any power source or batteries?

No batteries are needed. The MC-32 NC switches draw power directly from the alarm control circuit, eliminating maintenance and reducing overall system cost.

Are the switches compatible with smart‑home hubs?

They are compatible with most smart‑home hubs that support wired contact sensors, such as those using Z-Wave or Zigbee protocols, enabling automation and remote notifications.

What warranty coverage does Gtziqa provide?

Each MC-32 NC switch set includes a two‑year limited warranty covering manufacturing defects. Support is available through our technical service team for troubleshooting and replacement assistance.
