Hybrid Power/Signal Receptacle — 16 Signal + 4 Power Contacts
The Molex 459844122 is a 20-position receptacle from the EXTreme LPHPower 45984 series, designed with a hybrid contact layout of 16 signal and 4 power contacts across two rows.
Where the 20 Circuits Go — Signal vs Power Routing
The contact layout, typical of the LPHPower style, dedicates 16 positions to signal-level circuits and 4 positions to power delivery. This means a single connector body handles both a data bus and a DC rail — reducing the number of separate connectors on the board edge.
