TAGF‑SD19WH Flush‑Mount Steel‑Door Magnetic Contact (Reed Switch) – White, Normally Closed, 3/4″ Diameter, 1½″ Wide Gap, 12″ Leads

High‑quality flush (recessed) magnetic contact designed for steel doors. The TAGF‑SD19WH reed switch delivers a wide gap detection of 1½″ (≈ 38.1 mm) using a durable, high‑grade magnet encased in a thick plastic shell to withstand compression or crushing during installation. Ideal for perimeter security systems where discreet, reliable detection is required. White finish blends neatly with standard frames. Normal‑Closed (N/C) circuit configuration ensures that opening the door breaks the circuit, triggering alarm panels.
