Shielded high-flex drag chain cable
ARI220 Twisted-Pair Shielded Signal Cable, PUR
ARI220 PUR is a twisted-pair signal cable with an overall tinned copper braid. Pair twisting and shielding keep encoder and sensor signals stable while the cable moves. The PUR jacket gives high oil, abrasion and UV resistance and a wide temperature range.
Suited to
- Encoder and feedback lines on servo axes
- Sensor and low-level signal wiring in drag chains
- Cold or hot environments, from −25 °C to +90 °C in motion
