Roller Shutter Contact / Magnetic Reed Switch


Package Content



  • 1 × Magnetic Unit
  • 1 × Sensor Switch
  • 4 × Mounting Screws




Technical Specification: Type Normally Closed (NC)



Please Note: Our door reed switches are NC (Normally Closed). Please verify your requirements before ordering:



  • NC (Normally Closed): When the magnet is close to the sensor, the circuit is complete (current flows / light ON).
  • Open: When the magnet is separated from the sensor, the circuit is broken (current stops / light OFF).




Installation Instructions


For optimal performance, follow these installation guidelines for door and window magnets:



  1. Positioning: Install the permanent magnet on the moving part (door leaf/window) and the switch unit on the fixed frame or floor.
  2. Alignment: Ensure that the switch and magnet are aligned as precisely as possible. Significant deviation will move the contact out of the optimal magnetic field range, reducing the switching distance.
  3. Troubleshooting: If the alignment is poor, the switch may fail to detect the magnetic field, leading to malfunctions. We recommend marking and pre-positioning the components before drilling.
  4. Interference: Keep the magnetic contact away from external magnetic interference sources, such as transformers. Failure to do so may alter the operating characteristics and cause false triggering.

Note: This contact is ideally suited for roller shutters, garage doors, or industrial sliding gates.
