ARITECH INTRUSION DC104 Daily exchange magnetic contact with screw balanced GAP from 9 mm to 31 mm

Gap balanced screw exchange magnetic contact from 9 mm to 31 mm.

magnetic contacts are rhodium or ruthenium coated and are hermetically sealed in dry nitrogen. This provides excellent protection against bonding and provides a moisture-free environment that prevents the formation of corrosion. All magnetic contacts are encapsulated in an exclusive polyurethane-based insulation mixture that guarantees the correct balance between flexibility and maximum holding capacity. In the event that the support material expands or contracts due to increased humidity or drying, the mixture allows the contact container to flex and curve, preventing the reed from cracking. In addition, it remains resistant to temperature effects, while some mixtures may soften, causing a displacement of the reed with subsequent false alarms as the contact is moved away from the magnet
