## Description

20AWG 20/4 4 Core Shielded Wire CNC Wire (50FT) UL2464 Tinned Copper Core 20 Gauge Cable Speaker Wire for CNC Router Machine, CNC VFD Spindle, Electrical Appliance, Transformer and 3D Printer,etc: desertcart.com: Tools & Home Improvement

Review: Well made cable. Very flexible. - Nieces flexible. Perfect for the spindle on my small CNC router. It’s actually double shielded, foil and mesh. That’s nice. I wish it had a drain wire for the shielding, but it’s easy enough to ground the shield without the drain wire. If I build another CNC, I’ll definitely use this cable.
Review: Stepper motor cable - This cable worked out perfectly for an GRBL based CNC build. No sense in building without shielding everything, you would spend a lot of time tracing out gremlins caused by the stepper motors. Good price for the quantity and quality.

## Features

- 【Specification】50ft 20AWG Gauge 4 conductor wire(Red & Black&Yellow&White ). Rated voltage: 300V . Rated temperature : 80℃/176℉. Cond.resistance: 36.7Ω/KM20℃, Insulation resistance: 10MΩ/KM20℃, Dielectric test: 2000AC V/min.Material:PVC+Tinned Copper+Aluminum.
- 【Excellent shielded effect】There are double shielded layers(Aluminim& tinned copper) to achieve premium shielded effect. The shielding layer can shield this electromagnetic field inside the cable. Shielded cables also serve as grounding protection: if there is damage to the core wire of the cable, the leaked current can flow along the shielding layer, such as the grounding grid. At this point, shielded cables serve as safety protection.
- 【High Conductivity】Tinned copper not only has good electrical conductivity, but the tin coating also has the characteristics of strong corrosion resistance and oxidation resistance.It can greatly extend the service life comparing with ordinary copper wire. It is also more suitable for soldering.
- 【High quality copper material】 99% oxygen free copper materil to get better conductivity , and to extend working life of shielded wire. Pass RHOS2.0 and meets UL standards.
- 【Application】It is widely used in electronic instrument & device, electrical appliance, transformer and electrical motor, etc.
