Amphenol SurLok Plus Connectors for ESS and High-Voltage Applications

Electrification is pushing power architectures into higher voltage, higher current, and tighter packaging in EV/HEV platforms, energy storage systems, industrial automation, and heavy equipment. In these environments, the connector’s reliability and serviceability decision that affects safety, uptime, and maintenance cost.

Amphenol’s SurLok Plus™ Series is a next-generation sealed, field-installable high-power interconnect platform built around RADSOK® high-amperage contact technology. Designed as an alternative to traditional compression lugs, SurLok Plus™ supports industry-standard termination methods (crimp, screw, and busbar) while adding the sealing, keying, and quick-mating features demanded by modern electrified systems.

Accelerate SurLok Plus™ sourcing with IBS Electronics

Choosing the SurLok Plus™ family is the easy part. The real challenge is selecting the exact configuration that matches your design and assembly requirements keyway, RADSOK size, cable size, termination style, sealing class, and optional EMI/HVIL features.

IBS Electronics helps teams move your sourcing with:

✔ Engineering-backed configuration validation

Share a drawing, cable data, or enclosure constraints, IBS can help confirm the correct connector style and options for your voltage, current, and environment.

✔ Global supply network + lead-time flexibility

If your build schedule can’t wait, IBS can leverage global sourcing channels to reduce delays and improve availability.

✔ Prototype to production support

Whether you need 10 units for prototyping or 10,000+ for production, IBS supports repeatable supply with traceability expectations common in electrification programs.

Amphenol SurLok Plus™ is built for high-power electrification systems where safety, repeatability, sealing, and serviceability matter. When you’re ready to move from design to procurement, IBS Electronics can help you select the right configuration and source the exact MPNs reliably for prototype and production.
