Magnetic detectors are basic elements of a perimeter protection system. Medium-size  B-4M tight side magnetic detectors in a metal housing are designed for surface mounting. The metal screen protects the wiring against damage, which makes these detectors a perfect solution for locations particularly vulnerable to sabotage attempts or mechanical exposure. These detectors are screwed to a surface and provide an ideal solution for garage gate installation.
