Amphenol Industrial Operations has expanded its proven SurLok Plus high-power connector family with a 10.3mm straight plug engineered for fast, repeatable field installation and reliable performance in demanding environments. Built on R4 RADSOK contact technology, the new plug combines low contact resistance with excellent thermal behavior to support high-current, high-voltage architectures while helping teams shorten assembly time and simplify maintenance.
Designed for rugged duty cycles, the 10.3mm straight plug maintains electrical integrity where vibration, frequent service, and tight packaging constraints are part of daily operation. A quick-lock, press-to-release mechanism provides confident mating feedback and eliminates precision torquing steps—reducing rework risk and improving uptime in both production and field settings.
Electrical and environmental robustness are core to the design. The connector supports 1500 VDC system requirements with application-dependent current handling up to 320A, and its low-resistance contact geometry helps limit heat rise over time. Materials meeting UL94 V-0, IP67 sealing when mated, and a wide –40°C to +125°C operating range enable dependable performance across harsh, temperature-variable installations.
The straight plug is also optimized for integration efficiency. Its compact geometry simplifies routing in crowded panels and harness bundles, facilitates strain relief, and fits cleanly into enclosure and rack layouts. Compatibility with established crimp tooling and SurLok Plus assembly practices streamlines training, documentation, and line changeovers.
Target applications include HEV/EV battery systems, server and AI rack power, and industrial power. In each, the combination of high-power capability, field-installable hardware, and rugged construction allows OEMs and operators to standardize on a connector family that supports predictable service intervals and long-term reliability.
As part of the broader SurLok Plus platform, the 10.3mm straight plug leverages a mature ecosystem of keying, cable size, and accessory options—making it easier for buyers and distributors to consolidate SKUs, simplify inventory, and extend existing qualifications. The result is a versatile, cost-effective solution that drops into current SurLok Plus-based designs while providing the performance headroom modern systems demand.
The SurLok Plus 10.3mm straight plug is available now as an addition to the Amphenol Industrial Operations SurLok Plus product line. For specifications or ordering information, visit Sales & Support or contact us to learn more.
