Rectangular connectors come in various shapes, sizes and configurations, and the 861-83-026-40-001101 (861-series) is one such connector type. As a subset of the rectangular connection family, these connectors fall into the "headers, receptacles, female sockets" group, and have a specific application field and working principle. Keep reading to learn more about the functionality of this unique connector type.

The 861-series is a type of dual-row, single- or double-header female pin header connector. It is typically used for high-density signal and power connection, and provides a more reliable connection with fewer points for failure. The header is designed as a single or double row of female pins, while the mating receptacles are usually male contacts with spacing 0.5 mm or 0.635 mm. It also includes fixed and step-down floating contacts for the receptacle. Depending on the application, the 861-series can be certified to certain performance standards, including UL, CSA, RoHS, and VDE.

Due to its unique design, the 861-series connector is well-suited for applications where signal integrity and robust contact performance are key. It offers a reliable connection between multiple components and is also suitable for harsh and demanding environments, such as industrial or outdoor use. Additionally, its pluggable design makes it easy to replace or install connectors quickly and with minimal effort.

In terms of working principle, this connector type contains a set of spring fingers that contact with the headers sockets. These springs apply a reliable and consistent force to the connection as the connector is plugged and unplugged. Furthermore, its reliability is enhanced by the retention feature, which prevents the socket from becoming disconnected from the header during use. Additionally, the receptacle locking feature provides added security to ensure that the connection is secured and remains secure during the entire life cycle.

Overall, the 861-series provides reliable performance and a robust connection for applications where signal integrity is crucial. With its spring contact technology, robust strength for harsh environments, and pluggable design, this connector proves to be an affordable and efficient solution for many device connections. Furthermore, its locking feature ensures that the socket connection is secured and reliable throughout its life cycle.
