The 2PM series circular electrical connector is a high-reliability connector developed based on Russian connector technology and designed for electrical connection and signal transmission between professional electrical equipment. With its scientific structural design and stable electrical performance, the 2PM series effectively overcomes the limitations of many traditional connectors and provides a more convenient and reliable connection solution.
This 4 pin plug features a threaded coupling structure, ensuring a secure mechanical connection and preventing accidental disconnection caused by vibration or movement. The connector is widely used in industrial electrical systems requiring reliable power transmission, signal connection, and environmental resistance.
The 2PM series can be matched and interchanged with original Russian 2PMT and 2РМДТ series connectors, making it an ideal replacement choice for equipment using Russian standard electrical interfaces. The series also supports special versions including glass sintered sealed sockets and wall-mounted sealed sockets, which are suitable for demanding environments such as vacuum systems, sealed equipment, and high-temperature applications.
-- Designed according to Russian connector technology standards
-- Threaded connection structure provides secure locking and easy maintenance
-- Aluminum alloy die-cast shell offers high mechanical strength
-- Oxidation surface treatment improves corrosion resistance
-- Silver or gold-plated contacts provide stable electrical conductivity
-- Supports high current transmission with Φ2.0 and Φ3.0 contact sizes
-- Suitable for harsh environments including vacuum, sealing, and high temperature conditions
The connector is manufactured through precision machining and strict quality control to ensure accurate assembly, reliable contact performance, and long-term operational stability.
The 2PM connector completes electrical transmission through precisely manufactured contacts inside the plug and socket. The threaded fastening mechanism aligns and locks the connector securely, while the metal contacts provide efficient current and signal transmission. The insulation structure prevents electrical leakage and maintains safe operation under different environmental conditions.
