2PM Series Circular Electrical Connector
Product Information
The 2PM Series Circular Electrical Connector is designed for reliable electrical connection and signal transmission between electronic equipment. Its threaded mating structure provides a secure connection between the cable plug and panel receptacle, while the compact circular design supports practical installation in equipment with limited space.
A key feature of the 2PM Series is its sealed panel receptacle configuration. Glass-sintered sealed versions are available for applications requiring enhanced sealing performance, including vacuum, high-temperature and other demanding environments. The connector is rated for operating temperatures from -60°C to +200°C, providing flexibility for equipment used across a wide temperature range.
The series can also be matched and interchanged with corresponding original components of Russian 2PMT and 2РМДТ series, making it a practical option for replacement, maintenance and equipment integration.
