Magnetic Door Switch 12VDC- 220 VAC - 50 W

Overview

Enhance your security and automation projects with the MOKWN Magnetic Door Switch. This reliable sensor is designed to detect the opening and closing of doors, windows, and other access points. It consists of two parts: a magnet and a reed switch. When the magnet is in close proximity, the switch is closed; when separated, the switch opens, triggering your alarm or automation system. With a wide voltage range and robust construction, it's perfect for a variety of applications.

Key Features

• Wide Voltage Compatibility: Operates from 12VDC to 220VAC, making it suitable for low-voltage electronics and direct mains-powered alarms.
• Normally Open (NO) Reed Switch: The circuit is connected when the magnet is near, ensuring fail-safe detection.
• 50W Contact Rating: Handles moderate loads directly, or can be used to trigger relays and controllers.
• Easy Installation: Simple two-wire connection and surface-mount design.
• Compact and Durable: Small footprint fits discreetly on frames and edges.

Technical Specifications

• Voltage: 12VDC – 220VAC
• Switch Type: Normally Open (NO) – circuit closes when magnet is near
• Contact Capacity: 50W
• Wiring: 2 wires (connect to switch terminals)

Applications & Use Cases

• Home Security Alarms: Detect unauthorized door/window opening.
• Automation Projects: Trigger lights, cameras, or notifications when a door is opened.
• Access Control Systems: Monitor cabinet, gate, or drawer status.
• Robotics & IoT: Integrate with microcontrollers to detect physical state changes.
• Pet Doors and Enclosures: Alert when your pet enters or leaves.

What's Included

• 1x Magnetic Door Switch (reed switch unit)
• 1x Magnet (counterpart)
• 2x Mounting screws (if applicable)

Compatibility

• Works with any alarm system, relay module, or microcontroller (e.g., Arduino, Raspberry Pi) that can read a simple open/close signal.
• Can be used directly with 12V circuits or 220VAC alarms (within the 50W rating).
