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.
