For applications requiring miniature receptacles, Mill-Max offers four diverse, off-the-shelf products which will fulfill those needs. These receptacles are suitable for use in high density configurations down to 1 mm pitch.
Each receptacle contains our three-finger, beryllium copper contact. The contact is characterized by a low insertion force making it compatible with miniature leads subject to bending.
Two of the receptacles, 0439-0-15-15-04-27-04-0 and 8210-0-15-15-04-27-04-0, have solder tails for through-hole applications. Both of these receptacles have press-fit features suitable for mounting in insulators to make connectors.
The 4428-0-43-15-04-14-10-0 receptacle is a low profile, solder mount, open bottom receptacle fitted with Mill-Max’s Organic Fibre Plug. The OFP® provides a temporary solder barrier preventing solder paste from entering the contact area during assembly for paste-in-hole reflow soldering. After assembly, the fibre plug is knocked out when the mating lead is plugged in; the now open bottom allows long leaded devices to pass through. The 4428 series is available in bulk or on tape & reel for automatic assembly.
The last of the four receptacles is the 9928-0-15-15-04-27-40-0. It is a SMT receptacle mainly used for 1 mm grid socket configurations such as in BGA socket and adapter pairs.
The receptacle shells are made from brass alloy and, like all Mill-Max pins, are high-speed machined to precision tolerances. The inner contact is press-fit into the receptacle shell forming a gas-tight connection. It is precision stamped from beryllium copper strip and heat-treated to provide excellent spring and electrical properties. All four receptacles have a current rating of 2 amps.
Both the receptacle shells and contacts are gold-plated providing the highest interconnect reliability, corrosion protection and wear resistance.
