What this connector is
The Molex 464369321 is the 16-circuit right-angle member of the EXTreme Ten60Power 46436 family — a board-level power and signal hybrid receptacle built around two dedicated power contacts and fifteen signal contacts in a single housing. Press-fit termination secures it to the PCB through hole without soldering, which is the practical advantage at 60A — the press-tail spreads current across a larger plated-through barrel than a solder cup, reducing joint thermal resistance in high-current backplane applications. Gold contact plating at 30.0µin (0.76µm) is the thickest commercial grade for this series — the full gold thickness directly governs mating cycle durability and keeps first-mate contact resistance low across the connector's service life.
Key ratings and what they mean
The 60A current rating applies per circuit — the two dedicated power contacts carry the bulk load, while the fifteen signal contacts handle lower-current telemetry and control paths. Do not distribute the 60A across all sixteen positions; the signal contacts are sized for signal duty, not power sharing. Voltage rating is 600VAC or 250VDC — note the asymmetry. In AC backplane applications the 600VAC rating governs; in DC bus architectures the 250VDC ceiling is the constraint and must be respected, particularly in stacked or paralleled power layers. Operating temperature range is -40°C to 105°C. The upper limit of 105°C is the total-case temperature at the connector — in a high-current backplane the local ambient can approach this quickly, so verify thermal management in the actual stack-up before committing the full 60A per contact. UL94 V-0 flammability rating qualifies the housing for enclosed equipment enclosures and industrial control panels where fire containment is specified. Board guide and mating guide features help alignment during field replacement — the guides reduce the risk of bent pins on the mating header if the pair is mated off-axis in a tight enclosure.
Where this class of connector is used
EXTreme Ten60Power is a board-to-board power interconnect series — the 60A per circuit rating and press-fit termination are specifically matched to mid-plane and backplane architectures in industrial automation, data centre infrastructure, and power conversion equipment where a single high-current bus must distribute across multiple daughter cards.
