The small circular connector plays an essential role in providing stable power transmission, signal connection, and secure coupling for different applications. Due to its compact structure, threaded coupling design, and reliable connection capability, small circular connectors are widely used in electrical equipment, instruments, automation systems, and electronic applications requiring secure connections.

Hangzhou Kaipu Electronic Technique Co.,Ltd. focuses on the development and production of standardized connector products, providing reliable connection solutions with consistent quality and stable performance. Through standardized manufacturing processes and serialized product development, Kaipu offers connector products designed to support various electrical connection requirements.

The KP30 series circular electrical connectors feature small size, lightweight construction, threaded coupling, low contact resistance, reliable contact performance, and long service life. As the earliest-developed replacement for the RU PC series, KP30 connectors are fully interchangeable with the RU PC series (PC-4, PC-7, PC-10, PC-19, PC-32, PC-50), as well as domestic Y30 and Y4M series. They are widely used for electrical connections between electrical equipment, electronic instruments, and industrial control systems.

KP30 Series Circular Connector Improves Connection Reliability with Threaded Coupling

The performance of electrical connectors directly affects the stability and service life of electrical and electronic equipment. For equipment operating in industrial environments and applications with frequent connection and disconnection cycles, reliable contact performance and secure coupling are critical factors.

The KP30 series circular electrical connectors adopt a threaded coupling structure with low contact resistance (≤8mΩ) and reliable contact performance. These characteristics help maintain stable electrical connections, reduce signal loss, and support long service life during continuous equipment operation, even in vibration-prone environments.

As a standardized product, the KP30 series connectors are interchangeable with the RU PC series and similar products both domestically and internationally. This interchangeability simplifies procurement, replacement, and maintenance while keeping consistent electrical performance across different equipment and systems.
