Product Overview

The MC-38 Wired Door/Window Magnetic Sensor is a compact and reliable switch used to detect the opening and closing of doors or windows. It operates using a magnetic reed switch mechanism and provides a simple digital output, making it suitable for STEM experiments, security systems, and IoT-based projects.

This sensor is ideal for students, hobbyists, and developers who want to build practical automation and safety applications.

How It Works

The device consists of two parts:

A reed switch unit connected with wires
A magnet unit

When both parts are aligned and placed close together, the circuit remains closed. When the door or window opens, the magnet moves away from the reed switch, causing the circuit to open. This change can be detected and used to trigger an alarm or send a signal to a microcontroller.
