2PM Series 4 Pin Panel Socket – Glass-to-Metal Sealed Threaded Connector

Product Description

The 2PM Series 4 Pin Panel Socket is a high-reliability circular connector engineered for stable power and signal transmission in industrial electrical systems requiring secure panel installation and superior environmental sealing. Based on proven Russian connector technology, this panel socket combines a robust threaded coupling mechanism with a glass-to-metal sealed insulation structure, making it an excellent choice for applications exposed to high temperatures, pressure variations, and enclosed operating environments.

Designed with a 4-pin male contact configuration, the connector provides dependable electrical performance while supporting rated voltages up to 700V and current ratings from 5A to 30A, depending on the contact arrangement. The straight panel-mount design allows secure installation on equipment panels, reducing wiring complexity and simplifying system maintenance.

Unlike conventional insulation materials, the glass-sintered insulation forms a permanent hermetic seal between the contacts and the stainless steel housing. This construction improves insulation stability, minimizes moisture penetration, and delivers outstanding resistance to thermal expansion and mechanical stress. The connector is fully compatible and interchangeable with Russian 2PMT and 2РМДТ series connectors, making it an efficient solution for equipment upgrades, replacement projects, and new industrial system designs.

Key Features

-- Glass-to-metal sealed construction for enhanced environmental protection

-- Durable stainless steel housing with excellent corrosion resistance

-- Secure threaded coupling for stable mechanical connection

-- Compact 4-pin panel-mount configuration

Working Principle

The panel socket creates a reliable electrical interface by accurately aligning the male contacts with the mating plug. Once connected, the threaded locking mechanism provides consistent contact pressure and strong mechanical retention. The glass-to-metal sealing technology permanently bonds the contacts to the stainless steel shell, preventing leakage paths while maintaining excellent insulation performance and long-term connection stability.
