40-position power-plus-signal header
The 1241768-1 is the 40-circuit member of TE's Micro Power Quadlok header line, combining 24 signal positions with 16 power contacts in a single shrouded 4-wall housing. Tin-plated mating contacts and through-hole solder termination suit the part for automotive board-to-cable/wire applications within a -40°C to 80°C operating range.
Loaded-position distinction
The 1241768-1 carries 40 total positions, of which 24 are loaded with contacts — the remaining 16 are power cavities that accept the matching power terminal, allowing a single header to serve both signal and power routing.
