- NC MAGNETIC CONTACT SENSOR: Surface-mounted wired magnetic contact sensor with NC (normally closed) reed switch logic—magnet near = circuit conductive; magnet away = circuit disconnected for door/window status sensing.
- 18MM ± 6MM ACTUATION RANGE: Designed for an actuation distance of 18mm ± 6mm to help reduce false triggering from minor door alignment changes; ideal for stable open/close detection in security and automation circuits.
- SURFACE-MOUNT FAST INSTALL: Compact housings fit on doors, windows, cabinets, and drawers; screw-mount design supports quick positioning without recessing—use for home/office entry points, storage rooms, and equipment enclosures.
- COMPACT PLASTIC HOUSING: White plastic sensor and magnet set in a low-profile form; each unit measures 27 x 14 x 8mm (L x W x H) to sit neatly along frames while keeping wiring routed cleanly.
- WHAT YOU GET & SETUP TIPS: Includes 10 wired contact sets and 40 screws; align sensor and magnet faces, keep the gap within the rated range, and verify NC wiring with your controller before final tightening.
