The HK-004/4-FC is a high-performance 4-pin industrial connector optimized for harsh-environment applications, including factory automation, power distribution, and precision instrumentation systems. Its rugged FC-style locking mechanism ensures a tight, stable fit, making it ideal for vibration-prone industrial setups.
With an IP67 ingress protection rating, the connector effectively shields against dust infiltration and temporary water submersion, while its 16A current and 600V AC/DC ratings support consistent power and signal transmission for critical operational tasks. The corrosion-resistant metal housing further boosts its suitability for demanding industrial conditions.
Featuring a compact, lightweight design, the HK-004/4-FC enables easy installation even in space-constrained areas. It operates reliably across a wide temperature range of -40°C to 125°C, striking a perfect balance between durability and efficiency for industrial connectivity needs.
