What this 50-position header delivers
The 3-5176264-9: This is a 50-position, dual-row, unshrouded breakaway header from the AMPMODU series, on a 2.00mm pitch. Rated 200VAC and spanning -40°C to 105°C, it handles the thermal range of an industrial cabinet or an automotive interior without derating.
As an unshrouded header, it mates with any AMPMODU 2.00mm pitch receptacle housing that accepts 0.64mm square pins — no keying, so orientation is set by the board layout. The 0.079" (2.00mm) row spacing mirrors the pitch, keeping the pin grid square.
