Magnetic Reed Metal Switch Door Sensor with Wire MS-9 (Normal Open)
Magnetic Reed Metal Switch Door Sensor with Wire MS-9 (Normal Open)
The MS-9 Metal Magnetic Reed Switch is a heavy-duty surface-mount contact sensor designed for security, automation, and industrial applications. Built with a metal alloy housing, it offers superior durability and tamper resistance compared to plastic-bodied switches. This model is Normally Open (NO), meaning the circuit is open when the magnet and switch are aligned, and it closes when the magnet is moved away — triggering alarms or control systems. It is ideal for use in industrial doors, shutters, gates, and harsh environments where strength and reliability are critical.
Technical Specifications:
- Model: MS-9 (NO)
- Type: Magnetic Reed Switch (Normally Open)
- Design: Rectangular surface-mount metal housing
- Material: Die-cast metal alloy housing (grey finish)
- Switch Part Dimensions:
- Length: 49 mm
- Width: 19.5 mm
- Wire Length: 2.9 mm
- Magnet Part Dimensions: Similar size for easy alignment
- Contact Rating: 500 mA @ 100 V DC (typical)
- Operating Gap (Sensing Distance): 25–40 mm
- Wire Leads: 2-wire connection (approx. 300 mm length)
- Switch Type: Reed contact, NO (closes when magnet moves away)
- Mounting Style: Surface mount with screw holes (countersunk)
Features:
- Heavy-duty metal housing for strength and durability
- Normally Open (NO) reed switch design
- Resistant to tampering and harsh environments
- Wide sensing gap for reliable operation on large doors/shutters
- Surface mount with countersunk holes for secure fitting
- Compatible with alarm systems, automation controllers, and access control
- Long service life with stable performance
Applications:
- Industrial Security: Rolling shutters, warehouse doors, factory gates
- Commercial Security: Metal doors in offices, banks, and shops
- Residential Security: Main gates, garages, and metal doors
- Harsh Environments: Locations exposed to dust, vibration, or impact
- Automation Systems: Access control, IoT integration, and industrial monitoring
