VIMO KCHP01N High security contact ABS black Triple balance

KCHP01N IMQ approved for ferromagnetic surface on all internal windows. The triple magnetic balance protects this sensor from external magnetic fields that - if applied - cause the contact to open. The concatenation of the magnetic fields used for each contact constitutes a 'magnetic code'. The contact is equipped with 4 connecting clamps and a tamper against opening the lid of the reed part.
