metallic magnetic contact

Description

Metallic magnetic contact

Ncomponents

• Reed switch: A glass-encased switch containing two thin, ferrous reeds. It is highly responsive to magnetic fields.
• Magnet: A permanent magnet mounted on the movable part of the door or window.
• Housing: A sturdy metal casing (often steel or aluminum) that protects the reed switch and provides durability and tamper resistance.
• Wiring: Two or more wires connect the contact to the security system. Some contacts may have additional wires for tamper monitoring.

How it works

• Closed state: When the door or window is shut, the magnet is close to the reed switch. In a normally closed (NC) system, the circuit remains complete. In a normally open (NO) system, the circuit remains broken.
• Open state: When the door or window is opened, the magnet moves away from the reed switch. This disrupts the magnetic field. For an C system, the circuit breaks and triggers an alarm. For an O system, the circuit completes and triggers an alarm.

Performance and design specifications

• Sensing Distance: Typically 50−70mm50 minus 70 mm 50−70𝑚𝑚 or 1.9−2.71.9 minus 2.7 1.9−2.7 inches
• Material: Often zinc alloy or other durable, metallic materials to resist corrosion and for use on metal doors
• Cable/Wire: Often protected by a stainless steel hose or similar durable casing

Applications

• Residential, commercial, and industrial security: Used to monitor the status of doors, windows, and other access points to detect unauthorized entry.
• Tamper resistance: The metallic construction is more robust than plastic versions, making them suitable for environments where a higher level of security is required.
