2PM Series Threaded Circular Connectors
2PM series connectors are threaded circular electrical connectors designed for circuit
connection in electrical and electronic equipment. This series
features a threaded coupling structure, low contact resistance,
reliable mating performance, stable electrical connection, and
cost-effective use.
The plug and receptacle can be configured with pin contacts or
socket contacts according to different wiring and mating
requirements. With multiple shell sizes, contact arrangements,
mounting styles, and cable outlet structures available, the 2PM
series can meet various installation needs in industrial equipment,
electronic instruments, control systems, communication devices, and
other electrical applications.
The 2PM standard series is suitable for general electrical connection applications, while
the 2PMT series is designed for higher temperature working conditions. Depending
on the application, users can choose straight shielded plugs,
straight non-shielded plugs, panel receptacles, 90° angled shielded
plugs, 90° angled non-shielded plugs, or sealed receptacles.
Contact plating options include gold-plated contacts and
silver-plated contacts to meet different conductivity and
durability requirements.
