2PX series small circular electrical connectors are designed for circuit connection in electrical systems, radio devices, control equipment, and other compact electronic applications. The series provides plug and receptacle connection through threaded coupling nuts, allowing secure locking and stable electrical continuity.

Compared with simple plug-in structures, the threaded coupling method provides better mating stability and helps reduce the possibility of loosening during equipment operation. This makes the 2PX series suitable for applications that require reliable connection, compact structure, and convenient installation.

The connector series covers several versions for different working conditions. Standard 2PM and 2PM-type connectors are used for general electrical and radio circuit connection. Sealed 2PMГ and 2PMГ-type connectors are available for applications requiring improved protection at the connector interface. Sealed wall-penetrating 2PMГП and 2PMГП-type connectors are suitable for panel-through or wall-through installation where sealing and electrical connection must be maintained at the same time.

The domestic model is 2PX. Both 2PM and 2PM□ series products adopt the unified 2PX model number, and their combination codes are the same. This unified naming method supports easier product identification, ordering, replacement, and matching with existing equipment interfaces.
