SATEL B-1 magnetic door sensor white

The SATEL B-1 is a compact magnetic door sensor designed to detect unauthorised opening of doors and windows as part of a perimeter security system. This surface-mounted detector pairs a magnet with a reed switch to trigger an alarm the moment a protected entry point opens.

Reliable perimeter protection in a compact form

• Small sealed body ideal for discreet installation on doors and windows
• Surface mounting with choice of screw fixing or self-adhesive application
• Available in white finish for neat integration with light-coloured frames and trim
• Tight design resists tampering and environmental exposure

The B-1 works well for homeowners and small business operators who want straightforward entry-point monitoring without visible bulk. It suits residential doors, patio entrances, shop fronts, and window frames where a low-profile sensor is preferred.
