Description

roller shutter magnetic door contact

Functionality

• Detection: The device detects whether the roller shutter door is open or closed.
• Operation: When the door is shut, the magnet activates the reed switch, closing the circuit and signaling that the door is secured.
• Alarm Trigger: When the door is opened, the magnet moves away from the switch, which opens the circuit and sends a signal to an alarm system. 

• Durable construction: Often made with durable materials like metal zinc alloy or aluminum and designed to withstand frequent use and harsh conditions.
• Reliable performance: The magnetic operation ensures a reliable and consistent connection.
• Easy installation: The device is typically surface-mounted with an adjustable bracket for easy mounting and a specified operating gap (often around 50mm) to allow for some door movement without false alarms.
• Wired connection: Wired versions are seamlessly integrated into alarm systems for immediate notification.
• Tamper protection: Some models include tamper wires to trigger an alarm if someone tries to cut the wires. 

• Security systems: Widely used in home and commercial alarm systems to monitor access.
• Commercial and industrial settings: Suitable for various applications, from retail stores to industrial facilities.
• Energy efficiency: Can be used to integrate with automated systems that close shutters to conserve energy during periods of high sunlight.

• Operating Gap: Approximately 50mm (2 inches), though this can vary by model.
• Housing Material: Typically die-cast zinc or aluminum, chosen for its durability and resistance to corrosion.
• Cable Protection: Often features an armored cable, such as a flexible stainless steel sleeve, to protect the wiring from damage, wear, and tampering.
• Sealing: Many are IP67 rated, making them dustproof and protected against immersion in water, suitable for outdoor or harsh environments.
• Electrical:
  • Voltage: Up to 100VDC or 125VAC.
  • Switching Current: Up to 500mA.
  • Power Rating: Up to 10W.
