This matters in industrial environments where vibration can work a friction-fit connector loose over time. The IP20 rating means the header is finger-safe but not sealed; it belongs inside an enclosure, not in a washdown or outdoor location.
Ratings and compliance
Rated 30 A per circuit at 630 V, with the operating temperature range from -55°C to 105°C. The 30 A figure is per-contact at the rated temperature rise — derate above 105°C per the manufacturer's curve. The 630 V rating gives enough creepage for the 10.16 mm pitch to handle industrial control voltages and motor circuits without tracking.
Mates with the matching Dynamic D-5200 receptacle housing and crimp terminals — the tab contacts are rectangular, sized for the 30 A current rating. The gold-plated mating surface is designed for repeated mating cycles, so this header works in assemblies that see field service or periodic disconnection.
