Belden 9842 RS-485 Computer Cable, 24 AWG

If you need dependable data transmission for your computer networking application, the Belden 9842 series cable is a perfect choice.

The 9842 cable is a low capacitance computer cable designed for use with EIA RS-485 installations. It has two 24 AWG pairs stranded (7x32) tinned copper conductors. The nominal characteristic impedance is 120 Ohm.

The Belden 9842 cable features the signature Beldfoil® patented shield which offers lightweight, flexible, and strong shielding. It also uses polyethylene insulation (PE) for low dielectric loss and high dielectric strength.

The twisted pair construction helps to minimise external interference with data transmission, as the conductors carry signals in opposite directions to negate crosstalk.

Features and Benefits:

• Tinned copper conductors ensure optimal conductivity and resistance to corrosion
• Overall Beldfoil® (100% coverage) + tinned copper braid shield (90% coverage)
• PVC (Polyvinyl Chloride) outer jacket offers high durability
• 24 AWG stranded tinned copper drain wire
• Low capacitance provides reliable long-distance transmission

Applications:

RS-485
DMX-512

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.

Belden Data Cable,RS-485 Type, PVC Jacket - 9842 Series - 9842.0030

To stop information from getting lost in translation, fit this data cable from Belden. It's just what you need in a communication network, as it's an RS-485 type that delivers clean signals over long distances, even when there's a lot of background noise. Two twisted pairs carry signals in opposite directions to eliminate crosstalk and maximise the reliability of data transmission. Thanks to its superior flexibility, you can bend this cable around corners without affecting performance and with little chance of it cracking.

Features & Benefits

• Robust PVC jacket withstands abrasion in demanding settings
• Tinned copper conductors support optimal electrical flow
• Beldfoil shielding combines aluminium foil with polyester film to brush off electrostatic disruption and provide strength

Applications

• Telecommunications networks
• Medical centres
• Avionics
• Industrial automation

Can I use this data cable in humid locations?

Yes, the product is suitable to use in humid indoor settings, as its tinned copper conductors and PVC jacket resist corrosion.
