Alternative to Belden 3105A LSHF Data Cable - CPR Class B2ca s1a, d0, a1

Alternative to Belden 3105A LSHF Data Cable - CPR Class B2ca s1a, d0, a1

A high-performance alternative to Belden 3105A, this RS485 communication cable is designed for reliable data transmission in industrial automation, building management, and process control applications. Featuring a single 22AWG twisted pair with dual screening protection, it provides excellent resistance to electromagnetic interference (EMI), ensuring stable signal integrity in electrically noisy environments.

Suitable for RS485 and Modbus networks, the cable supports master/slave communication between intelligent automation devices including PLCs, HMIs, sensors, controllers, and other field equipment.

This high-performance RS485 communication cable is designed for reliable data transmission in industrial automation, building management, and process control applications. Constructed with a single 22AWG twisted pair and Foamed Polyethylene (FPE) insulation, it delivers excellent electrical performance and signal integrity.

The cable features a dual-screen design comprising 100% aluminium foil coverage and a 65% tinned copper wire braid, providing outstanding protection against electromagnetic interference. A tinned copper drain wire ensures effective grounding, making the cable ideal for electrically noisy environments.

Finished with a black Low Smoke Halogen Free (LSHF) outer sheath, this cable offers enhanced safety in public and commercial installations by reducing smoke and harmful gas emissions in the event of fire. Designed as a direct alternative to Belden 3105A, it is suitable for RS485 and Modbus networks connecting PLCs, controllers, sensors, HMIs, and other intelligent automation devices.
