RS485 Shielded Twisted Pair Cable – 2PR, 120Ω, LSZH, Low Capacitance

RS485 Shielded Twisted Pair Cable – 2PR, 120Ω, LSZH, Low Capacitance

This RS-485 2×2×1.0mm² shielded cable is engineered for reliable serial data transmission in industrial automation, building control, and Modbus/fieldbus networks. Featuring two individually shielded twisted pairs with an overall Al/PET + tinned copper braid shield (80% coverage), it provides superior noise immunity and signal integrity. The LSZH (Low Smoke Zero Halogen) jacket ensures safety in public and commercial buildings. With 120Ω characteristic impedance and low capacitance design, it supports stable communication over longer distances.
