RS PRO Door & Window Switch Surface Alarm Contact Proximity Switch White 78x20x24mm 918-4700

RS PRO 918-4700 Door & Window Switch Surface Alarm Contact Proximity Switch is a high-quality security sensor designed for industrial, commercial, and residential applications. This surface mount switch is engineered to provide discrete protection for doors and windows by means of a reliable magnetically operated reed switch. The white-coloured device measures 78 mm in width, 20 mm in height, and 24 mm in depth, making it compact and unobtrusive.

The switch incorporates a normally open (N/O) single pole single throw (SPST) reed switch housed in a moulded enclosure. The accompanying permanent actuating magnet is also moulded to facilitate easy fixing and reliable operation. This ensures precise actuation without false triggering caused by magnetic interference, which is detected and mitigated by the sensor design.

Additional security is provided by a built-in anti-tamper switch, preventing unauthorized bypass or tampering. The product includes interchangeable resistors, allowing seamless integration with a wide range of alarm panel systems. Installation is straightforward with spacer and mounting screws provided in the package.

This sensor supports supervised end-of-line monitoring, a critical feature for security-conscious environments to ensure status integrity of the switch line. It can also be fitted within shared security zones for enhanced configuration flexibility. The product is manufactured in the United Kingdom and complies with British Standard BS 4737 for alarm contacts, ensuring trusted quality and performance.
