Description
The 1035W-N Sentrol Surface Mount Reed Switch offers wide-gap magnetic sensing in a compact, adhesive-mounted format. Designed for installations where drilling is not practical, this contact uses a specialised 3M® adhesive backing that creates a strong bond while allowing repositioning during installation. Its wider 25.4mm operating gap makes it ideal for loose-fitting doors or windows where standard contacts may generate false alarms.
- Wide gap sensing – 25.4mm (1") operating gap helps reduce nuisance alarms caused by flexing or movement.
- Normally closed (NC) configuration – Standard for intrusion detection systems.
- 3M® adhesive mount – Installs without screws or drilling, suitable for delicate or finished surfaces.
- Low-profile housing – Discreet design with a small footprint for space-constrained applications.
- Flat-sided head – Ideal for mounting in tight spaces or flush against surfaces.
- Press-fit design – Adhesive allows repositioning within five minutes for precise alignment.
- 1/4" diameter – Slim profile suits narrow frames or inconspicuous mounting areas.
- High reliability – Rated for 10 million activations; each unit is hand soldered and factory tested.
- UL/ULC listed – Certified for use in professional security applications.
Optimised for windows, doors, and other openings where standard magnetic contacts may not fit or function reliably, the 1035W-N is a dependable option for both residential and commercial installations.
