Amphenol Industrial introduces a high amperage, single pole, plastic circular power connector for benign environment power applications. The Amphe-SP3 is ideal for outdoor power supply, control systems and communications environments in various industrial markets including hybrid and electric vehicle, heavy equipment, outer door LED and factory automation.


The compact, lightweight and cost-effective Amphe-SP3 uses silver-plated 5.7 mm RADSOK crimp-termination contacts, with gold-plated available, and can carry a current up to 120A. It features a lower insertion force and temperature rise than traditional contacts, providing longer life and the ability to be used in higher current applications at a given temperature.


This IP67-rated connector also features rubbers seals as well as a molded thermoplastic housing and insert. Each connector is designed with 90- and 120-color and keyway positions of different polarity to prevent mating mistakes and to ensure safety during operation. The connector is finger-proof in unmated applications to minimize contact with live contacts and prevent risk of shock.


The rugged connector can withstand up to 500 mating cycles at extended temperatures from -40°C to +125°C, salt fog spray to NACI 5% for 1,000 hours as well as shock and vibration of 980 m/s. Maximum operating voltage is 600 VAC and contact resistance is 5 million-ohms. Minimum insulation resistance is 5,000 mega-ohms at 25°C.
