The 2PM Series 7 Pin Threaded Circular Connector is engineered for stable power and signal transmission in industrial electrical systems that require high current capacity, secure mechanical locking, and long-term operational reliability. Based on proven Russian connector technology, the 2PM series is widely used in automation equipment, communication devices, power control systems, instrumentation, and other industrial applications where dependable electrical connections are essential.
Unlike conventional circular connectors, the 2PM series incorporates a robust threaded coupling mechanism that provides excellent resistance to vibration and accidental loosening. The connector is manufactured with a durable anodized die-cast aluminum alloy shell and precision-machined contacts to ensure consistent electrical performance under demanding operating conditions. It is also compatible with Russian 2PMT and 2РМДТ series connectors, making it a practical solution for equipment maintenance, replacement, and system upgrades.
Compatible panel receptacles with glass-to-metal hermetic sealing are available for applications requiring reliable performance in vacuum, sealed enclosures, or high-temperature environments.
Designed for dependable power and signal transmission in industrial equipment.
Threaded locking system provides a secure and vibration-resistant connection.
Supports up to 30A rated current for high-power electrical applications.
Straight plug design simplifies cable installation and maintenance.
Silver- or gold-plated contacts improve electrical conductivity and reduce oxidation.
Anodized aluminum alloy shell offers excellent mechanical strength and corrosion resistance.
Wide operating temperature range from -60°C to +200°C.
Compatible with Russian 2PMT and 2РМДТ connector series for convenient replacement.
The connector transfers electrical power and signals through precision-aligned contacts secured by a threaded coupling mechanism. After the connector is tightened, the threaded structure maintains stable contact pressure, reducing electrical resistance while improving resistance to vibration and mechanical movement. When used with compatible hermetically sealed receptacles, the connector system can support applications that require dependable sealing in demanding operating environments.
