Belden 658BMJ 0041000 Access Control Cable, 20 Core (2x22-3pr, 18-4c, 22-4c), Only Card Reader Pairs Shielded, Outer Jacket, CMP

Deploy consistent, low-noise connections across your security and access control installations with the Belden 658BMJ 0041000 plenum shielded cable. Designed for commercial and multi-tenant buildings, this plenum-rated (CMP) cable provides fire-safe routing through air-handling spaces while protecting sensitive card reader signals with dedicated shielded pairs. The 20-core assembly includes grouped conductors (2x22-3pr, 18-4c, 22-4c) for flexible wiring of readers, locks, sensors, and power without extra pulls or splices.

Belden's plenum shielded cable reduces electromagnetic interference where it matters most, improving reliability for access control, security, surveillance, and monitoring equipment. The rugged outer jacket resists wear during installation and in high-traffic pathways, while the selective shielding strategy balances cost and performance for large-scale deployments. Ideal for system integrators and facility managers, this cable simplifies runs and helps maintain clean signal integrity between card readers, controllers, and monitoring systems. Order the Belden 658BMJ for secure, code-compliant plenum installations and streamline your next access control or security deployment.
