The 1720430202: The locking ramp and board lock are both present. The locking ramp secures the mating receptacle housing against vibration — important in automotive or industrial machinery where a loose power connection means arcing. Finger-proof construction means the live blades are shielded from accidental contact, which is a safety requirement for a connector rated 600 V. The housing is black LCP (liquid crystal polymer), glass-filled, rated -40°C to 125°C. That temperature range covers under-hood automotive and industrial cabinet environments where the connector sees both engine heat and cold starts. The LCP material holds its dimensional stability through reflow and wave solder without warping.
600 V is the working voltage. The 7.50 mm pitch provides creepage distance for that rating. That thickness supports several hundred mating cycles.
The 1720430202 is the 2-position version of the same Super Sabre 172043 right-angle header. The 6-position sibling (1720430606 or 1720430602) shares the same 7.50 mm pitch, 30 A per circuit rating, 600 V, silver finish, board lock, and locking ramp. If your BOM calls for 2 positions, this is the one. If you need 6, the 1720430606 or 1720430602 are the drop-in replacements — same footprint per position, same mating receptacle family. No rewiring or panel modification needed beyond the position count.
