CQR Grade 2 Brown Multi Resistored Surface Contact

This magnetic door contact can be used in most security systems up to and including grade 2 and environmental class II as specified in EN50131-1 and is compliant to EN50131-2-6.

It operates as a EoL circuit changing the resistance value when the magnet housing is moved away from the contact housing. This contact can be used on windows and doors to detect the unauthorised entry of an intruder. The contact is also protected against tampering with optional detection of removal from its mounting surface.
