Application
Purpose-built for outdoor LED drivers, light poles and smart controllers — Zhaga / NEMA-compatible power plus DALI / 0-10V dimming interfaces that survive rain, UV, salt fog and pole vibration for 10+ years without re-work. From driver-to-module inside the luminaire to pole-base mains and rooftop sensor hubs.
Field Challenges
A luminaire may pass IP66 in the lab and still leak, corrode or rattle open after two winters on a coastal highway. The connector is the weakest gasket — these are the four failure modes YXY circular series are engineered against.
Wind-driven rain at 80–100 km/h, pressure washing and daily thermal breathing (55°C day to 8°C night) pump humid air into non-sealed joints. Water wicks along stranded wire into the pole base and driver cavity — tripped breakers, flicker, shorted drivers.
YXY answer: IP68 radial seal plus coupling O-ring, optional potted overmold — 1.5 m / 24 h submersion mated, IPX9K wash-down.
Coastal salt fog, de-icing chloride and industrial SO₂ attack plated steel contacts in 48–96 h; brass pins oxidize and contact resistance climbs toward thermal runaway. Galvanic couples at dissimilar-metal junctions corrode fastest on the pole.
YXY answer: Gold-plated copper contacts, 316 stainless / nickel-plated brass coupling — 96 h salt spray per IEC 60068-2-52.
An 8–12 m pole sways ±150 mm in wind; passing trucks add impulse gusts. Bayonet and push-fit joints work loose, contacts micro-fret and throw intermittent DALI faults. Threaded rings loosen further through thermal cycling.
YXY answer: Quick-lock quarter-turn plus secondary screw retention with anti-vibration ratchet — tested to EN 61373.
Up to 1,200 kWh/m² of UV per year chalks and micro-cracks non-stabilized nylon housings; the cracks become water tracks after Year 3 and expose live pins within 18 months on cheap ABS shells.
YXY answer: UV-stabilized PA66 V-0 shell, carbon-black + HALS package — 1,200 h xenon-arc with under 15% tensile loss.
Recommended Series
Mix and match per your luminaire, pole and controller architecture. All four share the IP68 sealing philosophy, UV-resistant PA66 shells and one crimp-die family, so crews standardize once for the whole project.
16 mm shell, 2–9 pin, 5A / 400V, IP68. Screw-lock or quick-lock; panel, cable and inline. Pre-wired overmold 0.5–1 m for driver-to-module and dimming pigtails.
Browse series
20 mm shell, 2–12 pin, 10–20A / 500V, IP68. Bayonet quick-lock with secondary screw, vibration-proof to EN 61373. Grid-to-pole mains, 4+PE for TN-S.
Browse series
Metric circular, 2–8 pin, 4–5A / 250–500V, IP67 / IP68. Screw-lock metal coupling, panel-mount for standard pole knockouts. DALI (A-code) and Ethernet (D-code).

Cat5e / Cat6, shielded, 1 Gbps, PoE+ 30W, IP68 mated, -40 to +85°C. Pass-through and panel couplers for 22 mm pole holes; smart controller backhaul and CCTV.

Maintenance crews work at height, in gloves, often at night — every extra minute on a cherry picker costs money and safety exposure. A street-light joint should close in one motion and prove itself sealed by sound, not by torque wrench.
| Joint step | Terminal block | YXY quick-lock |
|---|---|---|
| Strip, ferrule, torque, tape | Required, ~80 s | Not needed — overmold pigtail |
| Close the joint | Screws + insulate | Quarter-turn, click |
| Typical joint time | 92 s | 11 s |
| Exposed copper on site | Yes | None |
| Re-work after 2 winters | 2.1% of poles / yr | 0.25% / yr (audited) |
Timed trial: two electricians, 8 m pole, night shift — Shenzhen pilot, 120 poles. Across 200 poles the quick-lock section saved roughly 4.5 hours of lift time; a single luminaire re-work (truck, crew, lane closure) runs $180–$400.
