Magnetic Reed Switch FINEZAHS Industrial – ABS Housing, NC/NO, 3‑Set

Description

Product Overview

The FINEZAHS Magnetic Reed Switch is engineered for precise door and window monitoring in a variety of security and automation applications. Constructed from high‑strength ABS material, the housing resists heat, corrosion, and mechanical stress, ensuring long‑term reliability even in demanding environments. Each switch features dual contact configurations—Normally Closed (NC) and Normally Open (NO)—allowing flexible integration with alarm panels, LED indicators, relays, and low‑voltage control circuits. The reed element operates within a 10‑20 mm magnetic trigger range and supports up to 100 V DC, 0.5 A, and 10 W of power, making it suitable for both residential and industrial installations. The package includes three identical switches and twelve mounting screws, providing a cost‑effective solution for multi‑point security setups.

Usage

Designed for versatility, this magnetic reed switch can be deployed in home security systems to detect unauthorized entry, in commercial buildings for window and door status monitoring, and in industrial equipment where low‑voltage signaling is required. Its compact 55 × 12.5 × 11.5 mm form factor fits discreetly into tight spaces, while the ABS enclosure protects the internal reed from dust and moisture. Install the switch on a door frame and pair it with a matching magnet on the moving panel; when the magnet separates beyond the specified range, the circuit changes state, triggering an alarm or notification. The switch is also compatible with smart home hubs, access control panels, and HVAC systems that rely on simple binary signals.

FAQ

What is the difference between NC and NO contacts?

NC (Normally Closed) contacts keep the circuit closed when the magnet is present, opening only when the magnet moves away. NO (Normally Open) contacts keep the circuit open when the magnet is present, closing only when the magnet separates. Choose the type that matches your alarm logic.

Can the switch be used with a 12 V DC alarm system?

Yes. The switch is rated for up to 100 V DC, so a 12 V DC alarm or LED indicator can be safely connected without exceeding the voltage or current limits.

What is the recommended mounting distance for the magnet?

The optimal magnetic trigger range is 10‑20 mm. Mount the magnet within this distance from the reed switch to ensure reliable activation and avoid missed detections.

Is the product covered by a warranty?

All FINEZAHS Magnetic Reed Switches come with a one‑year limited warranty covering manufacturing defects. Our support team will help you with any warranty claim or replacement process.
