Product Description

■ RS485 Cable

RS485 cable refers to a type of cable that is used specifically to carry out the RS485 communication standard. It is usually a twisted pair cable consisting of two or three wires, two of which transmit the data, and the other one, which is optional, is for grounding. RS485 is the cable standard enforcing reliable data transmission even over long distances or in environment fluctuating electric fields. RS485 cables have the following attributes:

Twisted Pair: This reduces the electromagnetic interference (EMI) because the wires are twisted together.

Differential Signaling: RS485 employs a differential signaling technique, contributing to the reduction of noise by sending one wire the signal while the other wire sends a negative copy.

Long Distance: RS485 can send out data over longer distances (up to 1200 meters), maybe even double the distance encoded in some other serial communication standards.

Multi-drop Capability: The system cases are allowed for many devices to connect to the same bus (cable).

Industrial Applications: RS485 is frequently adopted in industrial automation processes, such as controlling robots and devices that are required to cross long distances while having noise immunity levels.

■ Common Types of RS485 Cables

Twisted Pair Cables: These are the most popular types, often with a shield guaranteeing additional EMP (Electromagnetic Interference) reduction.

Shielded Cables: Shielding protects noise interference via a shield as an additional protective element.

Unshielded Cables: These are applicable for the circumstances where the background noise is not so high.

Cat5/Cat6 Ethernet Cables: It is noticed that these wire connections are not purpose-built for RS485 communications; still, they could be used, providing they are within the range where the wires performance will not be degraded.

What is an RS485 Cable

■ When to use RS485 cables

Long distances: When data is transported over wiring length higher than 100 meters.

Noisy environments: When the signals are exposed to interference from other electrical equipment radiation.

Multi-drop networks: It is the situation when one bus serves several devices.

Industrial applications: Commonly used in critical industries, where reliability and long-distance communication are considered to be vital.
