1755778 – PHOENIX CONTACT

Overview

The PHOENIX CONTACT 1755778 is a robust 6-position terminal block header designed for reliable wire-to-board connections in industrial and commercial applications. Its 5.08mm pitch and shrouded design ensure secure mating and protection against accidental contact, critical for maintaining signal integrity in high-vibration environments. While its 12A current rating and 630V IEC voltage rating are substantial, designers must carefully consider the thermal management of the solder termination points under continuous maximum load to prevent derating and ensure long-term operational stability.
