2PM Series 4 Pin Circular Electrical Receptacle Connector – Shell Size 22

Product Overview

The 2PM Series 4 Pin Circular Electrical Receptacle Connector is designed for stable electrical connection and signal transmission in industrial equipment, control systems, communication devices, and other demanding applications. Developed based on Russian circular connector technology, this receptacle combines a compact structure with a threaded coupling mechanism to provide a secure and reliable connection.

The panel receptacle is available in standard versions as well as glass-to-metal sealed types, making it suitable for applications that require sealing performance, vacuum compatibility, or elevated operating temperatures. It is also designed for compatibility with corresponding Russian 2PMT and 2PMDT series connectors, providing greater flexibility for equipment maintenance and replacement.

Product Features

-- Threaded locking mechanism helps maintain a secure connection under vibration and frequent operation.

-- Aluminum alloy shell with surface oxidation treatment offers good corrosion resistance and mechanical durability.

-- Silver or gold plated contacts support stable electrical conductivity and help reduce contact resistance.

-- Compact shell size allows installation in equipment with limited mounting space.

-- Available with glass-to-metal sealed receptacles for applications requiring enhanced environmental sealing.

-- Compatible with matching connectors of Russian 2PMT and 2PMDT series for convenient replacement and integration.

Working Principle

The connector establishes electrical continuity through precision-machined contacts inside the receptacle. Once the mating plug is tightened using the threaded coupling, the contacts maintain stable power or signal transmission while the insulated housing separates individual circuits. The sealing structure helps protect internal contacts from external environmental influences when installed according to the recommended operating conditions.

Typical Applications

-- Industrial automation systems
