2PM Series 4 Pin Threaded Circular Receptacle Connector – Compatible with 2PMT & 2РМДТ

Product Description

The 2PM Series 4 Pin Circular Receptacle Connector is designed for reliable electrical connection and signal transmission in industrial, aerospace, and specialized electronic equipment. Developed using Russian connector technology, this series features a robust threaded coupling mechanism that provides a secure mechanical connection while maintaining stable electrical performance in demanding operating environments. Its compact construction and durable materials make it suitable for applications requiring dependable connectivity over long service periods.

The 2PM series is widely used for both power and signal transmission between electrical devices. Compared with conventional circular connectors, its optimized structural design provides convenient installation, reliable engagement, and consistent contact performance. The panel receptacle is available with glass-to-metal hermetic sealing options, including glass sintered sealed sockets (M) and wall sockets (C), making it suitable for applications requiring vacuum integrity, sealed installations, or elevated operating temperatures. The connector is fully compatible and intermateable with the Russian 2PMT and 2РМДТ connector series, simplifying equipment maintenance and replacement.

Key Features

-- Threaded coupling mechanism provides a secure and stable connection.

-- Four-pin configuration for reliable power or signal transmission.

-- Silver- or gold-plated contacts support consistent electrical conductivity.

-- Die-cast aluminum alloy shell with surface oxidation treatment offers excellent mechanical durability.

-- Optional hermetic sealing solutions are suitable for vacuum and sealed equipment.

-- Wide operating temperature range for demanding industrial environments.

-- Compatible with Russian 2PMT and 2РМДТ connector series.

Working Principle

The connector establishes electrical continuity through precision-machined conductive contacts housed inside an insulated circular shell. During installation, the threaded coupling securely joins the plug and receptacle, maintaining stable contact pressure while reducing the influence of vibration and mechanical movement. The conductive contacts provide efficient signal or power transmission, while the insulated housing separates individual circuits to maintain electrical isolation.
