Now also available in 3.6 mm: Amphenol SurLok Plus™ connectors at Rutronik


High reliability in harsh environments: Amphenol offers the SurLok PlusTM series, a highly reliable alternative to conventional compression lugs. With an IP 67 protection rating, it is a version of the original SurLok® series that is sealed against environmental influences. That makes it ideal for use in harsh, demanding environments. Energy storage, e-mobility, process control, and heavy equipment are the main markets and applications for this connector, which is available for order at .

SurLok PlusTM is available in smaller sizes (3.6mm, 5.7mm, 8.0mm) than its predecessor SurLok® and features a quick-lock and press-to-release design. Because Amphenol uses industry standards for crimp, screw, and busbar termination 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.
