Products Description
A cable built with multiple twisted wire pairs inside one outer jacket.
It is widely used for analog and digital instrument signals, such as 4-20mA and RS485. Each twisted-pair helps reduce electromagnetic interference and crosstalk between signal channels.
Different from multi-core instrumentation cable with single cores, this version groups conductors into pairs for balanced signal transmission. Marine-grade models can be supplied with ABS, DNV, LR certifications for ship and offshore use.
