23-position sealed header for harsh environments
The 4.00 mm pitch and 0.157" row spacing set the board footprint, and the shrouded 4-wall housing with a locking ramp keeps the mating connector secure under vibration.
Mounting and sealing details
The sealed housing (board guide and sealing features) means it can withstand washdown and moisture exposure typical in automotive underhood or industrial panel applications.
How it compares to similar headers
Compared to the TE ATX series header 4-1775099-7 (20 positions, 4.20 mm pitch, 9 A), the AMPSEAL 776087-2 offers a tighter 4.00 mm pitch and 23 positions, but its current rating depends on wire gauge rather than a fixed 9 A. The ATX header uses square pins; the AMPSEAL uses circular pins. Both have locking ramps and are shrouded, but the AMPSEAL is sealed while the ATX is not.
