Right-Angle Breakaway Header, 12 Circuits
The 22-28-8122: This is a 12-circuit right-angle breakaway pin header from the Molex KK 100 family.
ROHS3 compliant per the listed compliance status.
The breakaway pins are tin-plated, so the mating contact should also be tin-plated for galvanic compatibility — mixing gold and tin on the same interface can accelerate fretting corrosion in vibration environments.
