PVC Data Cables
Browse PVC data cables for indoor measurement, control and voice circuits in control panels, weighing equipment and intercom systems. Compare unscreened LiYY, copper-screened LiYCY and twisted-pair designs, including options with individual pair screens and an overall screen. Use the wiring diagram to specify the core or pair count. Check the datasheet for the bend radius, temperature limits and permitted movement of the selected cable.

Semi-Rigid PVC Data Cables for UL/CSA Projects
Compare cables with semi-rigid PVC core insulation and a PVC outer jacket for indoor equipment wiring. Options include unscreened, copper-screened, double-screened and twisted-pair constructions. Check the conductor size, voltage rating and installation limits for the exact model. If the equipment specification calls for a particular UL or CSA marking, verify it in the supporting documentation for the cable you plan to order.

FEP-Insulated Coaxial Cables
For broadband signal links, compare the 75-ohm RG 179 design with an FEP jacket and the 50-ohm RG 316 design with a TPE jacket. Both options in this range use FEP insulation. Match the impedance to the equipment and connectors, then check attenuation at the operating frequency for the proposed cable length. Review the jacket material if the cable contacts process fluids or the connector will be encapsulated.

Sensor Cables
Find compact sensor cables for measurement devices and test equipment. Compare FEP- and PFA-insulated designs by the temperature range of each construction. If the instrument specifies a maximum cable capacitance, check the datasheet value and the planned run length against that limit. Check the cable diameter and bend radius where it leaves the sensor, then verify the temperature limits and compatibility with any fluids it will encounter.
How to Specify a Flexible Data Cable
Start with the Signal and Connection
Use the device wiring diagram to record the signal type, working voltage, conductor size and core or pair count. For a sensor input, note any limits on cable capacitance or length. For a coaxial link, record the nominal impedance, operating frequency and permissible signal loss.
If the connector is already selected, use its drawing to check the conductor sizes, insulation diameters and jacket diameters it accepts. Include any intermediate connection or extension lead when reviewing the total length and electrical requirements of the link. For replacement work, record the cable marking and the terminal assignment at each end so you can compare the original and proposed constructions.
Specify Screening and Termination
Use the equipment documentation to determine whether the cable needs an overall screen, screens around individual pairs or both. Note where the route passes near drives or motor leads. If a multicore cable carries several signals, identify which conductors form pairs and which signals call for individual screening.
Put the screen termination method on the wiring drawing. For example, if the connector or gland must contact the screen, check its cable diameter range and how much room is available for termination. Include the connector part number when asking for a cable recommendation.
Check Movement, Temperature and Fit
Mark which sections stay fixed, move occasionally or bend during every machine cycle. Measure the available bend radius at cable entries and in moving sections. Where the route passes a hot component or contacts oil, fuel or cleaning agents, record the temperatures, fluids and duration of exposure.
For repeated bending in a cable carrier, compare high-flex data cables for drag chains against your signal requirements, available bend radius, travel and duty cycle.
Flexible Data Cable FAQs
What Is the Difference Between LiYY and LiYCY Data Cables?
In this range, LiYY is an unscreened PVC data cable and LiYCY uses an overall copper screen. Check the equipment’s screening and termination requirements. If the circuit calls for twisted pairs or individually screened pairs, confirm that arrangement on the selected cable’s datasheet.
How Do I Check Cable Capacitance for a Sensor Run?
Start with the instrument’s specified cable limit. Check whether the datasheet lists capacitance between conductors or between a conductor and the screen. Use the value that applies to the circuit and account for the full cable length, including any extension leads.
Need a Custom Data or Sensor Cable?
If your equipment needs a smaller cable diameter, a particular pair layout or a defined shielding arrangement, share the wiring diagram and connector drawings. Hulk can review the conductor layout, screening and insulation or jacket materials for your installation. Include the smallest cable entry and the exposure conditions at that point.
