The Growing Importance of Small Sealed Threaded Circular Connectors in Modern Electrical Applications

With the continuous development of electrical and electronic equipment and miniaturized industrial systems, compact and reliable electrical connection solutions have become increasingly important. The small sealed circular connector plays an essential role in providing stable signal transmission, low-power connection, and secure coupling for space-constrained applications. Due to its compact structure, reliable threaded coupling design, and sealed receptacle performance, small sealed circular connectors are widely used in electronic instruments, electrical equipment, industrial control devices, and precision systems requiring secure and space-saving 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 in industrial and instrumentation fields.

The Y4M series small circular electrical connectors feature a compact design with a metal aluminum housing for light weight, reliable threaded coupling, sealed receptacle structure, and simple operation. With gold-plated copper alloy contacts and high-performance insulation, they provide stable and reliable electrical connections for electronic instruments, electrical equipment, and industrial applications.

Y4M 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 wide temperature ranges, vibration-prone environments and applications with frequent connection and disconnection cycles, reliable contact performance and secure coupling are critical factors.

The Y4M series small circular 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 demanding temperature and vibration environments.

The Y4M series shares the same mounting dimensions as the Y4 series and is interchangeable with Y4 series connectors, providing excellent compatibility and flexible system integration. Pin and socket configurations can be interchanged according to customer requirements, offering flexibility across different equipment and systems.

Product Features of Y4M Series Circular Connectors Sealed Design and International Certification

Sealed performance and environmental adaptability are among the most important considerations for modern industrial and instrumentation connection systems. The Y4M series circular connector provides reliable electrical connections through a compact design with a metal aluminum housing and high-performance insulation, with a sealed receptacle structure for enhanced environmental protection.

Y4M series is a CE and RoHS certified small circular connector for reliable electrical connections. It operates reliably over a wide temperature range from -55°C to +125°C, withstands vibration (1~5000Hz, 20g) and shock (392m/s² acceleration), and maintains stable performance under high relative humidity (92% ~ 98% at 40±2°C), ensuring long-term reliable service in industrial and instrumentation environments.

Threaded Coupling and Flexible Mounting & Contact Options

Different electrical systems require different connection structures and mounting methods to support signal transmission and low-power supply. The Y4M series features threaded coupling for secure locking and simple operation, with gold-plated copper alloy contacts designed for reliable termination. Multiple contact configurations (3/4/5/7 contacts) with 3A current rating and low contact resistance provide flexible application in electronic instruments, electrical equipment, and compact industrial devices.

Two mounting options are available: flange mount and cable mount, to adapt to different equipment panel and cable assembly requirements. Pin and socket configurations can be customized according to customer needs, improving adaptability across various system designs.
