Magnetic detectors are basic elements of a perimeter protection system. Medium-size B-3A 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. They can only be mounted by screwing them to a surface.
