Belden Inc. 3106A 0092001 RS-485 Cable 120 Ohm 22 Awg

Product Description

The BELDEN INC. 3106A 0092001 is a shielded RS-485 data cable designed for reliable differential signal transmission in industrial and commercial control systems. Built with a single twisted pair at 22 AWG, it carries a characteristic impedance of 120 ohms, which matches the standard RS-485 bus termination requirement and helps minimize signal reflections over long runs. This cable is suited for use by electricians, controls technicians, and building automation installers who need a dependable conductor for low-voltage serial communication wiring.

This cable is used in RS-485 network installations including building automation systems, HVAC controls, programmable logic controllers, and industrial fieldbus applications. The 120-ohm impedance rating makes it a direct fit for RS-485 and RS-422 communication runs in both new construction and retrofit projects. It is sold per unit as a multimedia cable category product.

Key Features

• 120-ohm characteristic impedance matches RS-485 bus termination requirements
• 1 twisted pair construction at 22 AWG for differential signal integrity
• Designed for RS-485 and RS-422 serial communication applications
• Suitable for industrial and commercial low-voltage control wiring

Compatibility

Designed as an OEM-style replacement or standard installation cable for RS-485 serial communication networks in industrial controls, building automation, and HVAC system wiring applications.

Installation Notes

Installation should be performed by a licensed electrician or controls technician in accordance with NEC Article 800 or applicable low-voltage wiring codes. De-energize all connected control circuits and communication devices before making terminations. Maintain the twisted pair geometry as close to terminal points as possible to preserve impedance consistency and reduce noise susceptibility.
