08/31/2023 Product News

High reliability in harsh environments: Amphenol offers the SurLok PlusTM series, a highly reliable alternative to conventional compression lugs. With protection class IP 67, it is an environmentally sealed version of the original SurLok® series. This makes it ideal for use in harsh, demanding environments. Energy storage, e-mobility, process control, and heavy equipment are the key markets and applications for this connector, which can be ordered at

SurLok PlusTM is available in smaller sizes (3.6 mm, 5.7 mm, and 8.0 mm) than its predecessor SurLok®, and features a quick-lock and press-to-release design. Since Amphenol uses industry standards for the crimp, screw, and busbar connection options, no additional investment in special torque tools is required. This combination allows for straightforward on-site installation.

Three different colors (red, black, orange) and different mechanical coding options allow multiple SurLok PlusTM connectors to be used side by side without the risk of reverse polarity.
