RC-35 NC/NO Wired Magnetic Door/Window Contact Sensor – White (5 Set)

Description

Product Overview

The RC-35 NC/NO wired magnetic door/window contact sensor is engineered for precision detection in industrial and commercial environments. Constructed from high‑grade stainless steel contacts and a robust polymer housing, the sensor resists corrosion, dust, and mechanical impact. It operates at a rated voltage of 100 V and a maximum current of 500 mA, delivering a reliable 10 W power rating. The trigger distance of 15‑25 mm ensures swift response when a magnet is removed, making it ideal for security alarms, LED indicators, relays, and low‑voltage GPS devices. Each unit comes with clearly labeled wiring: red for normally closed (NC), black for normally open (NO), and white for common, simplifying installation and reducing wiring errors.

Usage

Designed for versatility, the RC-35 sensor can be mounted on wooden, metal, or composite doors and windows. Its compact size (16.7 × 10.7 mm) allows placement in tight spaces such as cabinet doors, equipment panels, and vehicle hatches. The 25 cm lead length provides enough reach to connect to control boards or alarm panels without additional extension cables. Typical applications include residential and commercial intrusion detection, industrial machine safety interlocks, refrigeration door monitoring, and smart home automation where reliable status feedback is essential.

FAQ

What is the maximum distance the sensor can detect a magnet?

The sensor reliably detects a magnet within a 15‑25 mm range, which covers most door and window applications.

Can the sensor be used with low‑voltage DC circuits?

Yes, the RC-35 operates up to 100 V and 500 mA, making it suitable for low‑voltage DC power supplies commonly found in alarm and automation systems.

Is the sensor compatible with existing alarm panels?

Absolutely. The standard NC/NO/COM wiring matches the input requirements of most commercial and residential alarm panels, allowing a plug‑and‑play installation.

How does the 90‑day guarantee work?

If the sensor fails due to manufacturing defects within 90 days of purchase, you can return it for a full refund or replacement, no questions asked.

What materials are used for the contacts?

The contacts are made from silver‑plated copper, providing excellent conductivity and resistance to oxidation over long periods of operation.
