2PM Series 4 Pin Threaded Circular Plug Connector for Industrial Power & Signal Transmission

Product Description

The 2PM Series 4 Pin Circular Plug Connector is engineered for reliable electrical connection and stable signal transmission in demanding industrial environments. Developed using advanced Russian connector technology, this connector combines a robust threaded locking mechanism with a compact structural design to ensure secure connections and long-term operational stability. It is designed to reduce connection failure caused by vibration, mechanical movement, or repeated mating, making it an ideal solution for professional electrical systems.

Constructed with a die-cast aluminum alloy shell featuring an oxidation-treated surface, the connector offers excellent mechanical strength, corrosion resistance, and durability. Silver- or gold-plated contacts provide low contact resistance, high conductivity, and dependable electrical performance for both power and signal applications. The connector supports rated voltages up to 700V AC and operates reliably across a wide temperature range from -60°C to +200°C.

The 2PM Series also offers optional glass-sintered sealed receptacles for applications requiring enhanced sealing performance, making it suitable for enclosed equipment and other demanding operating conditions. Designed to be compatible and interchangeable with the Russian 2PMT and 2РМДТ series, it provides an efficient upgrade or replacement solution without requiring major system modifications.

With its precision construction, reliable locking system, and high-performance materials, the 2PM Series connector is widely used in industrial automation, electronic control systems, power equipment, testing instruments, transportation equipment, and communication devices.
