Mill-Max Manufacturing Corp. Inc., Oyster Bay, N.Y., has launched a new target connector on 4-mm pitch designed for rugged applications incorporating a flanged base and hardware options for secure mounting. This target connector series is the mating half to the recently released 858 series ruggedized spring loaded connector.
Offered in 2-6 positions in through-hole, SMT and SMT with alignment pin versions, this new target connector series features a high temperature molded Nylon 46 housing that is compatible with RoHS soldering processes. Mounting tabs, integrated into the housing, provide a means for secure attachment to the PCB or product assembly. The tab holes may be specified with threaded inserts or left empty for other hardware requirements. The flanged base provides stability for the connector. The pins are plated with 10 micro inches hard gold over nickel for durability and excellent conductivity.
Additionally, these connectors are offered with the choice of either a flat or concave face on the mating side of the pins. The flat face style is 0.082 in. (2.08 mm) in diameter providing ample target area for the 0.050 in. (1.27 mm) diameter mating plunger. Concave face targets provide additional surface area when mated and can aid in centering/alignment of components fitted with spring loaded connectors during manual engagement.
Like all Mill-Max products, the new target pins employ high-speed precision turning with tight tolerances. The overall pin length tolerance of ±0.001 in. (0.0254 mm), combined with established in-house manufacturing and assembly techniques produce a connector with co-planarity of 0.005 in. (0.127 mm) or better. Advanced machining processes are employed to ensure there are no cut-off burrs on the face or SMT base of the pins to impede the electrical connection and attachment to the P.C.B. The table below provides details of the features for each part number in the series.
