Nascom B505AS/M N505AS ND Magnet, Black Anodized

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.
