Overview
Built for dependable door monitoring in commercial and industrial security systems, the Nascom N505AS magnetic contact delivers consistent, false-alarm-free performance where it matters most. This Nascom magnetic contact uses an N35 NdFeB rare-earth magnet and NO DEAD SPOT technology to provide extra-wide gap tolerance and smooth operation — reducing service calls and alarm noise caused by door warping or misalignment. The closed-loop (normally closed) configuration enhances alarm integrity for access control and intrusion detection applications. Constructed from extruded black anodized (Type II) aluminum and carrying a UL634 listing, the unit offers long-lasting durability and code-friendly compliance. Installers benefit from the 24" armored cable lead and 36" 22 AWG wire leads for secure, professional wiring in high-traffic doorways. At only 2" long, the compact block switch is ideal for man doors, server rooms, retail backdoors and other perimeter points requiring discreet, robust protection. Specify the Nascom B505AS/M N505AS magnetic contact for reliable security, surveillance and alarm monitoring — contact your supplier today to add it to your next project.
