What type of wire is standard for low-voltage milliamp signal systems?

The standard for low-voltage milliamp signal systems is single pair shielded wire. This type of wire is crucial because milliamp signals, often used in control circuits and instrumentation, are susceptible to electromagnetic interference (EMI) and noise, which can compromise the integrity of the signal.

Using a shielded wire helps to protect the signal from external sources of interference by grounding the shield, effectively creating a barrier around the conductors. This ensures that the signal remains stable and reliable, allowing for accurate measurements and control.

Single pair configuration is beneficial in low-voltage applications, as it minimizes the bulk and weight of the wiring, making installation more straightforward. This wire type is specifically designed to work in environments where low-level current signals are transmitted, ensuring the best performance and signal integrity.

Other wire types, while useful in different contexts, may not provide the same level of protection against interference, which is a critical requirement for effective low-voltage milliamp signal transmission.
