2PM Series 8 Pin Circular Electrical Receptacle
Product Description
The 2PM Series 8 Pin Circular Electrical Receptacle is designed for dependable electrical connection and signal transmission in demanding industrial, transportation, and professional equipment applications. Developed with reference to Russian connector technology, this receptacle features a compact structure, secure threaded coupling, and stable electrical performance. It is suitable for equipment that requires reliable operation under vibration, temperature fluctuations, or challenging environmental conditions.
The receptacle is available with glass-to-metal sealed panel socket options, making it suitable for applications requiring enhanced sealing performance, including vacuum systems, enclosed electrical equipment, and high-temperature environments. In addition, the connector is compatible with original Russian 2PMT and 2РМДТ series components, providing flexibility for equipment maintenance and replacement projects.
Product Features
-- Designed for stable power and signal transmission in industrial electrical systems.
-- Threaded locking mechanism helps maintain a secure and reliable connection during operation.
-- Aluminum alloy shell with surface oxidation treatment provides good mechanical strength and corrosion resistance.
-- Silver or gold plated contacts support consistent electrical conductivity and long-term performance.
-- Optional glass-to-metal sealed receptacle is suitable for applications requiring enhanced environmental sealing.
-- Compatible with corresponding Russian 2PMT and 2РМДТ series connectors for convenient replacement and system integration.
-- Wide operating temperature range supports use in low and high temperature environments.
Working Principle
The connector establishes electrical continuity through precision-machined conductive contacts housed inside a durable metal shell. Once the threaded coupling is fully engaged, stable contact pressure is maintained between the mating contacts, helping reduce connection instability caused by vibration or movement. The sealed structure also assists in protecting internal electrical components in demanding operating environments.
