Hybrid Power and Signal Receptacle for Backplane and Power Distribution
The TE Connectivity 1-6450162-2 is a MULTI-BEAM XL receptacle that mixes 12 signal contacts and 4 blade-type power contacts in a single 16-position, 4-row housing. Guide pins on the mating face help align the plug during blind-mate assembly — a practical feature when the connector is buried deep in a chassis.
The contact layout is 12 signal contacts and 4 power contacts — not a uniform 16-position array. The signal contacts are the female socket type, while the power contacts are blade sockets designed to accept the male blade from the mating header. If your circuit count calls for 16 identical signal lines, this is not the right part; the 4 power positions are physically larger and carry a different contact geometry. The 4-row arrangement spreads the signal and power across the connector body, which helps with thermal distribution when the power blades are loaded.
Board Fit and Assembly Considerations
The 0.100" pitch on the signal row matches standard 0.025" square post headers, so the footprint is straightforward. Board locks are integral to the through-hole tails — they provide mechanical retention during the solder process and add vibration resistance in the mated assembly. The guide pins are part of the connector body, not separate hardware, which simplifies the pick-and-place if the part is hand-loaded.
