2PM14K4QB2 4-Pin Circular Connector for Russian 2PM Standard

Robust: Built to Russian military specs for extreme conditions. Machined brass shell and precious metal contacts.
High contact density: Up to 37 gold or silver-plated contacts in a small circular interface. Enables power/signal transmission between armored vehicles, aircraft and weapons.
Keyed and locked: Shell is keyed and thread-locked to prevent disconnection under heavy vibration. Ensures proper mating even in low visibility.
Environmentally sealed: Meet IP68, immersible to 200m. Silicone/polyurethane seals block moisture, oils, chemicals from -60°C to +125°C.
5Customizable: Available with alternative platings (gold, silver), insulations (PTFE,PEI), inserts (fiber optic), protections (EMI/RFI shielding) and mounts (cable, panel) for specialized military uses.

About Russian Standard 2PM Connector

2PM series connector mainly adopts the technology of Russian connector, which is widely used in electrical connection and signal transmission between equipment, and its unique shape and structure design can make up some defects in use of many other similar connectors, such as the unique design of the shell threading hole and the tail screw, make it more convenient and scientific to use. The structural design of the internal insulator and pin socket also enhances its unique stability and reliability. This series of connectors also has a certain waterproof performance, which can prevent outdoor rain and other phenomena. Now there are mainly 2PM14-4, 2PM18 -4, 2PM18-7 and other specifications, its special structure and performance have won the general recognition of the market.

Yes, please advise the thread length for evaluation.

Can you assembly cable base on our requirement?

Yes, we can. Please send us the datasheet or connector and cable requirement, we can produce as per request.

Can you customize according to my datasheet/drawing?

Yes, please share it and the requirement with us, our engineer team will evaluate it.

RF Connector Specifications

What's the impedance of RF connector?

The impedance of an RF connector typically refers to the characteristic impedance of the transmission line it supports. The most common characteristic impedances for RF connectors are 50 ohms and 75 ohms. Please select an RF connector with the appropriate characteristic impedance to ensure optimal signal transmission and minimal signal loss within the system.

Order Lead Time

What is the lead time and availability of these connectors?

Lead time depends on the product type, quantity, and production status. For items ready in stock, the lead time is 3-5 working days. For common items, the lead time for 10K is 10-12 working days. The accurate lead time can be provided once the order is confirmed.
