Product details

The Molex 430452429 is a 24-position, dual-row shrouded header from the Micro-Fit 3.0 43045 series. The 3.00 mm pitch and 3.00 mm row spacing give enough creepage for the 600 V rating without forcing an oversized board footprint. Gold-plated mating contacts (30.0 µin) handle repeated mating cycles in automotive, industrial, medical, and telecom environments.

8 A per circuit at the rated temperature rise. The 600 V working voltage is supported by the 3.00 mm pitch and UL94 V-0 LCP housing.

Mates with the Micro-Fit 3.0 receptacle housing loaded with the matching crimp terminals.
