This 6381MD 0091000 cable is specialized OSDP (Open Supervised Device Protocol) communication cable designed for access control and security system installations. The cable features dual-purpose construction with 24 AWG single conductor shielded data cable paired with 18 AWG 2-conductor power cable, allowing you to run both data communication and power through single cable jacket. The shielded data pair helps protect signal integrity from electromagnetic interference, ensuring reliable communication between OSDP-compliant devices like card readers and control panels. The CMP (Communications Plenum) rating makes this cable suitable for installation in plenum spaces such as above drop ceilings and raised floors, meeting stringent fire safety codes. This configuration eliminates the need for separate data and power cable runs, simplifying installation and reducing labor costs. The cable is ideal for professional installers working on commercial security projects, building access control systems, and other applications requiring dependable OSDP connectivity with integrated power delivery.
