2PX42J50C2 Russian Standard Circle Electrical Connector 50 Pin Contacts

2PX Series Small Circular Electrical Connectors are compact electrical interconnection components designed for DC and AC circuit connection in electrical equipment, radio devices, control systems, instruments, and other space-limited electronic applications. The series uses a threaded coupling nut to connect the plug and receptacle, providing firm locking, stable contact performance, and reliable electrical continuity during equipment operation.

The threaded coupling structure gives the 2PX series better connection security than ordinary push-in connector designs. It helps prevent accidental loosening caused by movement, vibration, or repeated operation, making the series suitable for equipment that requires compact structure, dependable mating, and convenient installation.

According to different protection and installation requirements, this connector family includes several structural versions. Standard 2PM and 2PM-type connectors are mainly used for general electrical and radio circuit connection. 2PMГ and 2PMГ-type connectors are sealed versions, suitable for applications where the connector interface requires improved environmental protection. 2PMГП and 2PMГП-type connectors are sealed wall-penetrating versions, designed for panel-through or wall-through installation while maintaining both sealing performance and stable electrical connection.

The domestic replacement model is 2PX. The 2PM and 2PM□ series adopt the unified 2PX model designation, and their combination codes are consistent. This unified model system makes product identification, model matching, ordering, replacement, and equipment maintenance more efficient.
