6.35 mm pitch, locking ramp, 12A per circuit
It mates with the corresponding receptacle to make a board-to-cable connection. The 0.250-inch (6.35 mm) pitch sets the board footprint and the per-contact current ceiling — at 12 A the temperature rise stays within the polyamide housing's limits.
Tin contacts, UL94 V-0, -40 to 105°C
Tin is a workhorse finish for low-cycle applications — it handles 25 to 50 mating cycles before fretting becomes a concern. In a panel that gets disconnected a few times a year for maintenance, that's a solid decade of service. Rated 600VAC — that's the dielectric withstand between adjacent circuits at the 6.35 mm pitch.
