Field Application & Problem Solved
On older IRB paint cells the biggest headache is a cracked valve cable right at the wrist—solvent wicks up the strands, copper turns green, and you lose atomiser trigger mid-pass. 3HNE09058-1 is the factory replacement for the A3-axis “2-valve signal” run. It carries 24 VDC to the colour-change block and to the atomiser trigger, all in one PUR jacket that survives 5 million drag-chain cycles. You’ll find it on every IRB 5500/6700 paint line, hanging off the side of the colour-changer, running down the dress-pack to the wrist. Core value: it’s robot-grade flex, so you don’t get intermittent valve faults after six months of 2 m/s bends.

Installation & Maintenance Pitfalls (Expert Tips)
Don’t over-bend at the wrist – Minimum bend radius 10×OD. Kink it once and you’ll see “valve not ready” every other coat cycle.
Seal the gland – If you leave the cable gland loose, solvent creeps inside and copper turns green in a week. Tighten until you feel the compression ring bite, then ¼-turn more.
Colour code your connectors – A3 bulkhead uses keyed circular, but the key is subtle. If you force 180° out, you’ll bend pins and buy a new $200 robot-side connector.
Cable tie discipline – Dress-pack ties every 100 mm. Miss one and the cable rubs on the robot base—PUR jacket wears through in 3 months.
Test under motion – After replacement, run the robot through the full paint cycle at 100 % speed. If you see “valve timeout” only at high accel, the cable is still too tight—loosen the dress-pack clamp.

Technical Deep Dive & Overview
3HNE09058-1 is a multi-core PUR cable factory-terminated for ABB paint cells. Inside: two 24 VDC pairs plus shield, rated 300 V, oil/solvent resistant per ABB PUR spec. The robot-side connector is a circular, keyed, IP65 unit that mates with the A3 bulkhead; cabinet side is usually flying leads into the colour-changer terminal strip. No electronics inside—just copper and rubber—so failure mode is mechanical fatigue or chemical ingress. Lose 24 V and both valves drop—tie it to the same PSU feeding the colour-changer to avoid nuisance trips.
