OLINK HA Series Heavy Duty Connector 3+PE/4+PE/5+PE/7+PE

· Housing Material: Die-cast aluminum alloy with powder coating, delivering impact resistance and corrosion protection far beyond plastic housings for demanding industrial environments.
· Ingress Protection: IP65 waterproof and dustproof with rubber sealing gasket at the mating face and PG cable gland at the rear entry, blocking moisture, oil, and dust under water jet exposure.
· Contact Performance: Silver-plated copper alloy pins and sockets with contact resistance ≤1mΩ, minimizing power loss and temperature rise under continuous load.
· Insulation Integrity: ≥10GΩ insulation resistance between contacts and housing, with 4kV impulse withstand voltage for reliable surge protection.
· Fire Safety: Polycarbonate insert certified UL94 V0 flame retardant, self-extinguishing with zero flame propagation under overload or fire exposure.
· Corrosion Resistance: Passed 72-hour salt spray test, ensuring long-term reliability in marine, coastal, outdoor, and chemically aggressive environments.
· Temperature Range: -40°C to +125°C operating range, maintaining electrical and mechanical performance across extreme cold starts and high-temperature duty cycles.

· Mounting Options: Surface mount for panels, bulkhead mount for through-wall, and cable-to-cable inline - one connector series for all layouts.

· Certifications: CE certified and RoHS compliant, with 100 percent batch testing on contact resistance and insulation before shipment.
