Belden 9842 Cable, 152m Reel, 9842.00152
The 9842.00152 2-pair stranded (7x32) cable has 120 Ohm nominal characteristic impedance. The voltage for this unit is 300V. The twisted pair construction helps minimise external interference with data transmission, as the conductors carry signals in opposite directions to negate crosstalk.
This Belden 9842 cable also features Polyethylene insulation (PE), which has low dielectric loss and high dielectric strength. The outer jacket is PVC (Polyvinyl Chloride), offering high durability. It uses the patented Beldfoil® shield which provides flexible, lightweight, and strong shielding.
This cable has an operating temperature range of -30°C to +80°C to allow for application flexibility.

What is RS-485?
This term refers to an industry standard for defining the electrical characteristics of serial lines in serial communication systems (methods of sending data). This standard is useful for industrial control systems as it ensures signal transmission over long distances and electrically noisy environments, in installations where many devices may need to be interconnected.
What are the benefits of shielded cabling?
Cables which are screened, or shielded, are better protected again electromagnetic interference (EMI) than unshielded versions. EMI refers to electrical noise which is conducted or radiated, and it can negatively affect the functioning of devices and equipment. Screening reduces crosstalk between cables (signal leakage), ensuring higher signal integrity.
