The 1.25-mm compact locking HPI connector is suitable for signal transmission within devices or in low-power applications. With its smaller size (saving up to 20% of PCB space*) and higher current-carrying capacity (up to 3 times*), this connector offers greater design flexibility. The external locking mechanism ensures a secure connection and prevents accidental disconnection, thereby enhancing the reliability of the interconnect system. This series of connectors meets the needs of slim-profile applications requiring reliable, secure wire-to-board signal or low-power connections.
