Product Specification

2PM Series 7 Pin Circular Connector Straight Plug 30A Threaded Electrical Connector

Product Overview

The 2PM Series 7 Pin Circular Electrical Connector is designed for stable power connection and signal transmission between industrial electronic equipment. Based on Russian connector technology, the 2PM series features a reliable structure, secure threaded coupling, and durable materials to support electrical systems requiring consistent performance under challenging operating conditions.

This straight plug connector adopts a 7-pin configuration with Φ3.0 mm contacts, providing a suitable solution for applications requiring higher current transmission capability. The threaded connection method ensures strong mechanical engagement between plug and socket, helping maintain connection stability during vibration, mechanical movement, or long-term operation.

The connector shell is manufactured from die-cast aluminum alloy with surface oxidation treatment, offering mechanical protection and improved resistance to environmental influences. The 2PM series can be matched and interchanged with original 2PMT and 2РМДТ series connectors, making it suitable for equipment replacement, maintenance, and system upgrades. For applications requiring additional sealing performance, glass-sintered sealed panel sockets are available for vacuum, sealed, and high-temperature environments.

Key Features

• 7-pin circular design supports reliable power and signal transmission.

• High current capability up to 30A for demanding electrical applications.

• Threaded coupling structure provides secure locking and stable connection.

• Straight plug configuration simplifies cable installation and routing.

• Silver or gold-plated contacts improve conductivity and oxidation resistance.

• Aluminum alloy die-cast shell provides mechanical strength and durability.

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

• Compatible with 2PMT and 2РМДТ series connectors.

• Suitable for industrial equipment requiring reliable circular connections.

Working Principle

The connector transfers electrical current and signals through accurately positioned contacts inside the circular housing. The threaded coupling mechanism locks the plug and socket together, maintaining consistent contact pressure and reducing connection instability caused by vibration or mechanical stress. The contact plating helps maintain electrical performance by improving surface conductivity and resistance to oxidation.

When combined with glass-sintered sealed sockets, the connector system can support applications requiring enhanced sealing performance in vacuum, enclosed, or high-temperature environments.
