RS485 Communication Cable · 120Ω Shielded Signal Cable

RS485 1Px22AWG + 1Cx22AWG Cable

RS485 1Px22AWG + 1Cx22AWG Cable is designed for 120Ω industrial and building communication circuits where one twisted communication pair and one additional 22AWG core are required in the same cable. It is suitable for engineers, system integrators, contractors and distributors working on RS485, BMS, access control, automation and low-voltage signal wiring projects. Key specifications include tinned copper conductors, FPE/PVC insulation, AL/PET shield, drain wire, tinned copper braid, PVC jacket, 120Ω impedance and 300V signal rating. Before ordering, buyers should confirm cable route, shielding requirement, jacket material, fire test requirement, printing, packing and project documentation.

Project Condition Recommended Direction Why It Matters What to Confirm
Project requires RS485 communication Choose a 120Ω RS485 communication cable. RS485 systems normally require controlled impedance for stable communication. Confirm 120Ω requirement in the project specification.
One pair is not enough for wiring design Choose 1Px22AWG + 1Cx22AWG construction. The additional core supports project-specific wiring needs. Confirm the function of the extra core.
High EMI or noisy environment Use AL/PET shield + tinned copper braid construction. Shielding helps reduce interference risk. Confirm shield grounding and installation route.
Cable installed in conduit, tray or cabinet Check 7.8±0.5 mm OD. OD affects conduit filling, cable glands and wiring space. Confirm installation space and bend handling.
Customer requires project documentation Request datasheet and sample before bulk order. Reduces mismatch between specification and delivered cable. Confirm datasheet format, test items and document language.
Fire requirement is specified Check CM fire test listing and required documents. Fire requirements vary by market and project. Confirm whether certificate-related documents are needed.
Custom printing or distributor label is needed Confirm printing, label and packing before order. Avoids rework in packaging and delivery. Confirm logo, text, meter marking, reel/carton label.
Outdoor, wet or harsh environment Review jacket and environmental requirements first. The listed jacket is PVC and operating temperature is -20°C to +60°C. Confirm if special jacket material is required.
Long communication distance Review DCR and capacitance. Resistance and capacitance affect signal performance over distance. Confirm run length, baud rate and device requirements.
Buyer compares with power cable Do not use this as a power cable. The specification states 300V and not for power purposes. Confirm application is signal/control communication only.

Comparison With Alternatives

This Product Alternative Product Difference When to Choose Risk
RS485 1Px22AWG + 1Cx22AWG Cable RS485 1Px22AWG Cable This product includes one additional 22AWG core. Choose this product when the project needs one RS485 pair plus one extra conductor. Choosing 1P only may leave no spare/control conductor.
RS485 1Px22AWG + 1Cx22AWG Cable RS485 2Px22AWG Cable This product has 1 pair + 1 core, not 2 full pairs. Choose this product when only one RS485 pair plus one extra core is required. Choosing 2P may increase cable size or cost if the second pair is not needed.
RS485 1Px22AWG + 1Cx22AWG Cable Unshielded control cable This product has AL/PET foil, drain wire and tinned copper braid. Choose this product when interference resistance is important. Unshielded cable may cause communication instability in noisy environments.

FAQ

RS485 1Px22AWG + 1Cx22AWG Cable FAQ

What is RS485 1Px22AWG + 1Cx22AWG Cable used for?

It is used for RS485 communication and low-voltage signal wiring where one 22AWG communication pair and one additional 22AWG core are required in the same cable. Typical uses include BMS, automation, control systems, access control and monitoring networks.

What does 1Px22AWG + 1Cx22AWG mean?

1P means one pair of 22AWG conductors, and 1C means one additional 22AWG single core. This structure is useful when the project needs one RS485 communication pair plus one extra conductor.

Is this cable suitable for RS485 communication?

Yes. The specification lists 120Ω characteristic impedance, which is a key requirement for RS485 communication cable selection. Buyers should still confirm project distance, baud rate, termination and grounding design before ordering.

What conductor material is used?

The cable uses TC conductors, which means tinned copper. The conductor size is 7×0.25±0.01 mm for both the communication pair and the additional core.

What shielding structure does this cable have?

The cable uses AL/PET foil shield, tinned copper drain wire and tinned copper braid. The braid density is listed as ≥80%. This structure supports signal protection in environments where interference may be present.

What is the jacket material?

The listed jacket material is PVC. The jacket color is black, the nominal average jacket thickness is 1.20 mm, and the overall cable diameter is 7.8±0.5 mm.

Can this cable be used for power transmission?

No. The specification lists rated voltage as 300V and clearly notes “not for power purposes.” This product should be used as a communication or signal cable, not as a power cable.

What operating temperature range does this cable support?

The operating temperature listed in the specification is -20°C to +60°C. Buyers should confirm the actual installation environment before ordering, especially for outdoor, hot, wet or harsh conditions.

Can I request a sample before bulk order?

Yes. Sample review is recommended before bulk order, especially for project use. Buyers should check conductor size, cable OD, jacket, printing, shielding, color code and terminal compatibility during sample review.

Can ZION provide a datasheet?

Yes. Buyers can request the datasheet for engineering review. The datasheet should be used to confirm construction, dimensions, electrical characteristics and application suitability before procurement.

Can ZION provide certificate-related documents?

Certificate-related document needs should be confirmed with ZION before order. The supplied specification lists Fire Test: CM, but buyers should confirm the required certificate, test report or compliance document for their specific market or project.

Is customization available?

Customization can be discussed based on project requirements. Buyers should confirm jacket material, color, printing, label, packing, construction changes and documentation requirements before quotation.

What is the MOQ?

MOQ is not listed in the provided specification. Buyers should contact ZION with the required construction, quantity, packing and customization requirements so the sales team can confirm the applicable MOQ.

What affects lead time and what should be confirmed before bulk order?

Lead time may be affected by quantity, customization, printing, packing, document requirements and production schedule. Before bulk order, confirm SKU, cable construction, conductor size, insulation color, jacket material, cable OD, shielding requirement, fire test requirement, printing, packing, datasheet, sample approval and required project documents.
