2PX Series Electrical Connectors are small-size circular electrical connectors developed for reliable circuit interconnection in electrical equipment and radio devices. The connector system includes plug and receptacle combinations that are fastened by threaded coupling nuts, providing a firm and stable mechanical connection.

The 2PX series is suitable for applications requiring compact connector size, stable electrical contact, and reliable mating performance. The threaded coupling structure helps prevent accidental loosening and supports dependable use during equipment installation, operation, and maintenance.

Different versions are available according to sealing and installation requirements. The 2PM and 2PM-type connectors are used for general circuit connection applications. The 2PMГ and 2PMГ-type connectors are sealed versions, suitable for conditions where additional environmental protection is required. The 2PMГП and 2PMГП-type connectors are sealed wall-penetrating versions, designed for equipment structures where the connector needs to pass through a housing or panel.

For domestic use, this connector family is represented by the model 2PX. The 2PM and 2PM□ series are integrated under the unified 2PX model number system, with the same combination codes, helping simplify product selection, model matching, and technical communication.
