The HEE-040-FC is a high-performance heavy-duty electrical connector designed for power transmission in industrial automation, renewable energy storage systems, and heavy equipment control panels. Built with a corrosion-resistant zinc alloy housing and silver-plated copper contacts, it offers excellent resistance to vibration, thermal shock, and chemical exposure, ensuring long-term reliability in harsh operating environments.
Rated for 40A current and 500V AC/DC, this connector delivers low-resistance, stable power transfer for medium-to-heavy load applications. It supports flexible panel-mount and cable-mount configurations, with an operating temperature range of -50°C to 140°C and an IP67 rating that protects against dust ingress and temporary water submersion.
Featuring a precision twist-lock mechanism, the HEE-040-FC enables tool-free, secure mating and prevents accidental disconnection during operation. Fully compliant with IEC 61984 and RoHS standards, it meets strict global safety and environmental requirements, making it a dependable solution for high-power connectivity needs.
