The ML-203R is a wired recessed magnetic contact for alarm systems. Its flush-mount design allows it to be embedded inside the door or window frame, leaving only a small cylindrical body visible. It operates reliably at separation distances of up to 2 cm between the magnet and switch halves.

The unit is suitable for a broad range of door and window types and is supplied in white to match standard frame finishes.
