OHS Series Ultra-Small Bayonet Circular Connector
Product Information
The OHS Series Ultra-Small Circular Connector is designed for compact electrical equipment where installation space and quick connection are important. Based on Russian connector technology, the series is suitable for DC and AC circuits used in electrical, radio and control instruments.
Its most distinctive feature is the ultra-small circular design combined with a bayonet coupling mechanism. The bayonet structure enables fast mating and removal while maintaining a secure mechanical connection. Multi-level key positions help guide connector orientation during installation and reduce the risk of incorrect mating between corresponding components.
The connector consists of plugs and sockets. The socket is designed without a tail attachment, while the plug is equipped with a straight plastic tail attachment. Copper-alloy contacts with silver or gold plating provide a conductive contact surface for reliable electrical and signal transmission. The series can also be matched and interchanged with corresponding original components of the Russian ОНЦ-БС-1(2) series.

Working Principle & Applications
The connector transfers electrical power or signals through its mating contacts. During connection, the bayonet mechanism guides the plug into the socket and locks the two components through a short rotational movement. The key-position structure helps maintain the required mating orientation.
The OHS Series is suitable for compact electrical instruments, control instruments, electronic equipment, radio equipment, testing devices and other AC/DC electrical connection applications.
Advantages & Service
The combination of compact dimensions, quick bayonet coupling and multiple key positions makes the OHS Series particularly useful where space saving and convenient operation are priorities. We support sample orders, bulk purchasing, product selection and application-based connector matching.
