Russian Standard 2PM Series Circular Connector for Rail Transit Systems

The 2PM Series Russian Standard Circular Connector is designed to provide stable and secure electrical connections in demanding rail transit environments. With its threaded coupling mechanism and rugged metal housing, the 2PM connector ensures reliable power and signal transmission in metro systems, high-speed trains, locomotives, and railway control cabinets.

Built to withstand vibration, mechanical shock, and temperature fluctuations, the 2PM series is widely used in onboard electrical systems, signaling modules, traction control units, and auxiliary railway equipment.
2PM Connector

Engineered for Railway Reliability

Rail transit systems require connectors that maintain stable performance under continuous vibration and harsh operating conditions. The 2PM series features:

Secure threaded locking structure for anti-vibration stability

High-strength metal shell for mechanical protection

Reliable contact performance with low contact resistance

Long service life in industrial railway environments

These characteristics make it an ideal solution for railway electrical interconnection systems.

2PM Connector

Available Models & Configurations

The 2PM series offers multiple shell sizes and contact layouts to meet different railway system requirements:

2PM14-4 / 2PM14-7 – Compact size for low-pin signal transmission
