Harwin boosts choice of SMT PCB sockets
Expanding its portfolio of board sockets, Harwin has introduced additional sizes for the Sycamore contact range. These 6A current rated surface-mount PCB sockets allow engineers to accommodate different designs, placing individual sockets freely on a board without the constraint of connector housings.
Two additions complement the existing 3.87mm length sockets, which accept 0.8-1.3mm or 1.5-1.9mm mating pins. These new versions have longer body lengths of 5.87mm, which means that they are suitable for incorporation into deeper PCBs and capable of accommodating longer mating pins. Although both are bottom entry, they can be inverted to serve as top entry sockets.
Harwin says that key to the design of these PCB sockets are the three points of contact, as opposed to the two points of contact found in other surface mount sockets feature. As a result, an electric connection is said to be always maintained, with no risk of a break in continuity, even when subject to vibrational forces.
These sockets have gold plating to maximise conductivity and reduce mechanical wear, ensuring long-term operation with a 500 mating cycle durability. A working temperature range of -50 degrees C to +125 degrees C is supported owing to its use of Beryllium copper material.
Among the applications suited to Sycamore contacts are battery management systems of electric vehicles, solid state lighting panels, domestic and commercial grade gas detection systems, fire alarms and smart metering equipment. As they are surface mount, and supplied on tape and reel, they are much simpler for PCB designers to apply to their products, especially when high-volume manufacturing processes are being employed. This means that a separate placement or soldering operation is not required, so production throughput is maintained at high levels.
Harwin is produces interconnect solutions that can deal with demanding applications in defence, aerospace, space, industrial, oil/gas and motorsport sectors.
