Mill-Max Manufacturing Corp., Inc. announces the development of a new minimal insertion length contact, expanding our range of receptacles designed to work with shorter mating leads. The receptacles being introduced here are fitted with a new, beryllium copper contact clip which is characterized by an early engagement contact point, dual entry capability, low contact resistance and high current carrying capacity.

The new receptacles accept lead diameters from .037” – .043” with a minimum mating lead length of .058” for top entry insertion. This is a 30% reduction in required lead length from our current receptacle offerings.  The reduction is due to the hourglass design and extended contact surface area, eliminating the need for excess protrusion through its fingers for reliable electrical contact.  The ability to use shorter mating pins provides several advantages such as compressed packaging, shorter electrical signal paths and lower potential RF signal interference.

The 0448 is a closed bottom, solder mount receptacle with a .025” low profile height above the board.  It is designed to be soldered in a .071” minimum mounting hole.  The 0640 is a zero profile, solderless press-fit receptacle with an overall length of .105”.  This part features a hexagon shaped head designed to be press-fit into a .085” ǿ plated through hole.  When pressed in the 0640 sits flush with the P.C.B. surface.  The 0640 is also open bottom allowing for mating pin entry from either end.  The minimum mating pin length for bottom entry is .060” from the bottom of the receptacle.  This dual entry feature allows for flexibility in component placement and assembly of boards and modules.
