2PM18K7WB1 Russian Connector Circular Electrical Connector 7 Socket Contacts
The 2PM series connectors are high-reliability circular electrical connectors designed with a secure threaded coupling structure. This connection method provides firm mating, strong vibration resistance, and stable electrical transmission during long-term use. The connectors are widely applied in electrical equipment, electronic instruments, industrial control systems, communication devices, and other applications requiring dependable signal or power connection.
The 2PM series features low contact resistance, reliable contact performance, easy installation, and economical cost, making it suitable for both standard industrial use and equipment maintenance applications. The plug and receptacle can be assembled with either pin contacts or socket contacts, allowing flexible configuration according to different circuit requirements.
The standard 2PM series is manufactured according to Russian standards, while the 2PMT series is specially designed for high-temperature working environments where improved thermal resistance is required.
