Harwin has recently expanded its portfolio of printed circuit board socket products, launching more sizes for the popular Sycamore Contact series in the market. Engineers can use these surface mount PCB sockets with a rated current of 6A for different designs, and each socket can be freely placed on the circuit board without being limited by the connector housing.

Harwin has launched two new products that complement the existing 3.87mm socket length and can accept 0.8-1.3mm or 1.5-1.9mm plug pins. These new products have a longer body length of 5.87mm, which means they are suitable for integration into deeper PCBs and can accommodate longer plug pins. Although both are bottom entrances, they can be inverted to serve as top entrance sockets.

The key to designing these PCB sockets is that they have three contacts, while other surface mount sockets only have two contacts. Therefore, electrical connections can be maintained at all times without the risk of interruption of continuity, even under the influence of vibration forces.

These sockets have a gold-plated design to maximize conductivity, reduce mechanical wear, ensure long-term operation, and have high durability with 500 insertion and extraction cycles. Due to the use of beryllium copper material, it can support a working temperature range of -50 to+125 ℃. The latest Sycamore Contacts can provide higher value for applications such as battery management systems for electric vehicles, solid-state lighting panels, household and commercial grade gas detection systems, fire alarms, intelligent metering devices, etc. Due to the fact that these products are surface mount and provided in rolls, it is easier for PCB designers to integrate them into the product, especially suitable for large-scale manufacturing processes. This means that there is no need for separate placement or welding operations, thus maintaining a high throughput rate in the production process.
