Jablotron SA-204 — Surface wired magnetic contact

The SA-204 is a surface-mounted metallic magnetic contact designed for industrial environments and installations on metal doors and frames. It provides a robust mechanical housing suited to harsher conditions where plastic contacts are not ideal.

Key physical parameters include a compact footprint of 49×17×9 mm and a maximum working distance of up to 40 mm. The device is supplied as a wired, two‑wire magnetic contact with a normally-closed (NC) alarm output, allowing straightforward connection to standard intrusion alarm panels.

The metallic construction and surface design make the SA-204 particularly suitable for metal doors or other steel structures where reliable contact sensing is required. The factory-attached cable is approximately 650 mm long, facilitating direct wiring during installation.

Installation notes:

  • Intended for surface mounting; align magnet and contact carefully to maintain the specified working distance.
  • Two‑wire NC output is compatible with common alarm inputs—verify wiring conventions on the control panel before connecting.
  • Designed as a basic door/window contact for intrusion detection in industrial and commercial systems.

SA-204 offers a simple, durable solution for detecting door/window openings in industrial settings. For system integration, observe panel input requirements and routing best practices for the cable.
