Plastic power connector Amphenol ELR3A03 designed for space constrained electric vehicle applications
Product Overview
The Amphenol Industrial ePower-Lite is a plastic power connector series engineered for the hybrid electric vehicle (HEV) and electric vehicle (EV) markets. It offers 2, 3, and 4-pole configurations, featuring patented RADSOK technology for higher amperage, reduced T-rise and voltage drop, and lower resistance. The robust, lightweight plastic shell withstands high temperatures up to 125C and provides dielectric protection. Its compact design is ideal for space-constrained applications in EVs, and it is field installable and repairable. The series includes Connector Position Assurance (CPA) for mated confirmation, making it a preferred interconnect solution for EV and HEV applications.
