The Wires Zone 2 Pack Overhead Door Floor Garage Shutter Contact Sensor Security Alarm Switch

SKU CH-FXQ5-FQPC6

Two-pack overhead door contact sensor with magnet bracket, 3" operating gap, and armored cable for security alarm circuits

  • TypeOther
  • Overhead mounting simplifies installation on garage shutters
  • Heavy-duty roller shutter contact withstands demanding environments
  • Magnet on bracket ensures reliable alignment every time
  • 3-inch minimum operating gap tolerates door movement
  • 30-inch PVC cable with 21-inch armored sleeve resists wear

Overhead Door Contact Sensor Pair

This two-pack supplies magnet-operated switches for overhead garage doors and roller shutters. Each unit closes its detection loop when the magnet sits next to the switch and opens it when the door moves away. The sensors are designed for low-voltage security circuits only.

Thermals Noise Power Draw

Passive magnetic operation produces no heat, no audible noise and no power consumption during normal use. The 22AWG PVC cable with a 21-1/2" armored sleeve carries the signal without active electronics. No external supply or battery is required for the contact function.

Included Mounting Hardware Effect

Two mounting brackets measuring 82mm by 55mm by 31mm and two contacts at 105mm by 45mm by 10mm are supplied for direct installation. The magnet fixes to the bracket, allowing a minimum 3-inch operating gap for flexible alignment. The armored sleeve protects the cable from physical damage on moving doors.

Questions about this item

How do I mount the overhead switch and magnet bracket on a roller shutter?

Fix the switch bracket (82mm x 55mm x 31mm) to the door frame and the magnet bracket to the moving shutter so they align within the 3-inch minimum gap. Route the 30-3/4" PVC 22AWG cable with its 21-1/2" armored sleeve away from pinch points. The step often missed is verifying the magnet triggers the reed switch before final tightening.

What parts might need replacement after long-term use on a garage door?

The 21-1/2" armored sleeve protects the 22AWG wires from repeated flexing; inspect it annually for cracks or abrasion where it bends. The magnet holds its field indefinitely, but the reed switch inside the 105mm x 45mm x 10mm contact can fatigue after millions of cycles, causing intermittent opens.

At what point does the contact stop detecting the magnet reliably during daily operation?

The reed switch requires the magnet to stay within the 3-inch minimum operating gap; vibration or bracket shift that pushes the gap beyond this distance opens the loop even when the door is closed. The 22AWG cable and armored sleeve do not affect magnetic range.
