2PM Russian Standard (GOST) Industrial Connector


High Reliability for Harsh Environments

The 2PM series is a line of circular connectors engineered to meet Russian GOST standards, purpose-built for heavy-duty industrial, railway, military, and aerospace applications. Designed to thrive in extreme conditions, these connectors deliver consistent, uninterrupted performance even when faced with severe vibration, wide temperature swings, and moisture ingress. Whether for power transmission or critical signal connections, they offer a robust, compliant solution for projects requiring adherence to Russian technical specifications.

2PM Connector


Key Features

Robust, Corrosion-Resistant Build: Housed in aluminum alloy shell with a nickel-plated finish, the connector stands up to harsh outdoor and industrial environments.

2PM Connector


High-Temperature Insulation: Premium PA66 or PBT thermoplastic insulation maintains stable electrical performance across a wide temperature range, from -55°C to +125°C, and delivers UL94 V-0 flame retardancy for added safety.

2PM Connector


Secure, Fast Locking: Choose between a bayonet quick-lock mechanism (1/4 turn) for rapid, vibration-resistant connections, or a threaded lock for enhanced IP67/IP68 sealing in the most demanding conditions.

2PM Connector


Long-Lasting Conductivity: Silver-plated contacts ensure low-resistance connectivity and reliable performance through over 500 mating cycles.

IP67 Ingress Protection: The dustproof and waterproof design guarantees reliable operation in outdoor, marine, and high-dust industrial settings.
