Unique-Bargains 5 Pcs Recessed Door Window Magnetic Reed Switch Alarm Normally Open Control Sensor

SKU CH-D74Y-0HYK0

Five normally-open magnetic reed switches trigger alarm circuits when a magnet moves beyond 15 mm, each with a 33 cm cable

  • TypeHome Automation - Sensor & Accessories
  • 5-piece pack secures multiple entry points
  • Normally open reed switch activates only when magnet approaches
  • 15 mm actuation distance covers standard door and window gaps
  • 33 cm cable allows flexible recessed mounting
  • ABS housing resists impact in home or factory use

Recessed Magnetic Reed Switches

This pack contains five normally open reed switches designed for recessed installation in doors or windows. When a magnet approaches within the actuation distance the circuit closes, sending a signal to the connected alarm system. The sensors suit home automation projects and light commercial security setups where discreet mounting is required. Each unit ships new in a brown ABS housing.

100 V 10 W Switching With Short Cable

The contacts are rated for 100 volts and 10 watts, suitable for low voltage alarm circuits rather than mains switching. A 33 cm lead provides enough length for typical frame routing without excess slack. Actuation occurs between 0 and 15 mm, so the magnet must sit close to the switch body for reliable operation. Power draw is negligible when the circuit is open.

Five Piece Pack With Compact ABS Bodies

Each sensor measures approximately 2.5 by 2.3 cm and weighs 80 g for the complete set of five. The brown ABS housing blends with wooden frames and resists everyday knocks. Recessed mounting means drilling a hole in the frame, which suits permanent installations but not temporary or rental scenarios. The short cable limits placement to positions near the control panel or junction box.

Questions about this item

How far apart can the magnet and sensor be mounted for reliable actuation?

The reed switch actuates at 0-15 mm; keep the magnet within this gap when aligning the recessed housings.

What upkeep does the ABS housing and 33 cm cable need over time?

Inspect the brown ABS casings for cracks and the 33 cm leads for insulation damage; replace any sensor that shows physical wear.

At what load does the 10 W rating become the limiting factor during continuous operation?

The contact is rated for 10 W at 100 V; sustained switching above this power level will degrade the reed element first.
