Product Specification

2PM Series 20 Pin Circular Electrical Connector Plug

Product Description

The 2PM Series 20 Pin Circular Electrical Connector Plug is designed to provide secure electrical connectivity for equipment operating in demanding industrial environments. Developed using proven Russian connector technology, this connector features a robust threaded coupling mechanism that delivers reliable mechanical locking and stable electrical performance. The mixed-contact configuration of Φ1.5 and Φ3.0 contacts allows simultaneous transmission of both signal and higher-current power circuits, making it suitable for multifunctional electrical systems.

Constructed with a die-cast aluminum alloy shell and precision-plated contacts, the connector offers excellent resistance to vibration, corrosion, and temperature fluctuations. When paired with the corresponding glass-to-metal sealed panel sockets, the connector system can be used in sealed, vacuum, and high-temperature applications. It is fully compatible with original Russian 2PMT and 2РМДТ series connectors, making replacement and equipment maintenance simple and efficient.

Key Features

• -- Mixed-contact design with 20 positions (Φ1.5 + Φ3.0) for power and signal transmission.

• -- Durable die-cast aluminum alloy housing with oxidation surface treatment.

• -- Silver or gold plated contacts for improved conductivity and reduced contact loss.

• -- Secure threaded coupling prevents accidental loosening during operation.

• -- Excellent resistance to vibration, dust, and harsh industrial conditions.

• -- Wide operating temperature range from -60℃ to +200℃.

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

• -- Suitable for long-term operation in high-reliability electrical systems.

Working Principle

The connector transfers electrical signals and power through precision-engineered contacts that are securely aligned by the threaded locking structure. The dual-size contact arrangement enables different current ratings within one connector, while the optional hermetically sealed socket protects internal circuits against moisture, pressure changes, and extreme operating temperatures.
