2PM Series 4 Pin Circular Receptacle – Threaded Panel Connector

Product Description

The 2PM Series 4 Pin Circular Receptacle is engineered for reliable electrical connection and stable signal transmission in industrial and professional electronic systems. Designed using mature circular connector technology, this receptacle combines a compact structure with a secure threaded coupling mechanism to ensure dependable performance under demanding operating conditions. Its robust construction makes installation straightforward while maintaining excellent mechanical stability during long-term operation.

The 2PM Series is suitable for both AC and DC electrical applications and supports operating voltages up to 700V AC. The threaded connection between the cable plug and panel receptacle provides strong retention, helping to maintain stable electrical contact even in environments with vibration or frequent equipment operation. Available with glass-to-metal sealed receptacle options, the series can satisfy applications requiring enhanced sealing performance, including equipment exposed to vacuum, high temperatures, or enclosed operating environments.

Manufactured with a die-cast aluminum alloy shell featuring an oxidation-treated surface, together with precision silver- or gold-plated contacts, the connector offers excellent conductivity, corrosion resistance, and long-term reliability. The 2PM Series is fully compatible and interchangeable with Russian 2PMT and 2РМДТ series connectors, providing an efficient solution for equipment upgrades, maintenance, and replacement without changing existing interfaces.

Key Features

-- Secure threaded coupling for reliable mechanical connection

-- Compact 4-pin configuration for signal and power transmission
