Cabo de dados Belden OSDP RS485, 1 par, 24 AWG fio, cobre estanhado, blindagem geral Beldfoil, bainha PVC, cinzento

This Belden OSDP RS485 cable is a professional-grade data communication cable engineered for reliable, low-speed serial communication in access control and security systems. With a single twisted pair of 24 AWG stranded tinned copper conductors, it delivers consistent signal integrity over extended distances, making it a solid foundation for OSDP and RS-485/EIA-485 networks.

Advantages

The cable features an overall Beldfoil® shield (aluminum foil-polyester tape) that provides excellent protection against electromagnetic interference, ensuring stable data transmission in electrically noisy environments. The stranded tinned copper conductors offer superior flexibility and corrosion resistance, facilitating easy installation and long-term reliability. The PVC jacket is durable and flame-retardant (UL 1685 CM), meeting rigorous safety standards for commercial installations.

Suitable for

• OSDP (Open Supervised Device Protocol) communication between access control panels and readers
