Twisted Pair Shielded Cable

Twisted pair shielded cable refers to a metal shielding layer between the twisted pair and the outer insulation sleeve. The shielding layer can reduce radiation, prevent information from being eavesdropped, and also prevent the entry of external electromagnetic interference, making shielded twisted pair cables have a higher transmission rate than similar unshielded twisted pair cables. Twisted pair shielded cables are widely used in motor control and motion control applications due to their advantages such as noise immunity, wide common mode range, appropriate data transmission rate, and multi-point transmission capability. Other applications may also use this communication technology due to the advantages of twisted pair cables, including process control networks, industrial automation, remote control, building automation, and security systems. Due to the need for stable data transmission over a considerable distance in these applications, shielded twisted pair technology is adopted. In industrial control applications, due to the inclusion of a motor mechanical brake in the motor control system that is prone to high electrical noise and has high current accuracy, safety and reliability must be considered when designing the communication path of the controller.

Twisted pair shielded cables balance the transmission of audio signals and fixed railway signals, with excellent anti-interference performance. They can be used separately for single pairs or simultaneously for multiple pairs, and transmit multiple signals with excellent performance. They can partially transmit power. The usage characteristics and structure of railway signal cables. Twisted pair cables can be used in general situations, but in environments with higher requirements, shielded twisted pair cables can be used. The longest transmission distance can reach 1200 meters, but in practical applications, the transmission distance also varies due to the transmission characteristics of chips and cables.
