Product Description


Russian ОНЦ Series Bayonet Circular Connector Plug – 50 Pin Female

Product Description

The Russian ОНЦ Series Bayonet Circular Connector Plug is a compact multi-pin electrical connector designed for reliable signal and low-power transmission in industrial control and electronic systems. Featuring a secure bayonet locking mechanism, the connector enables quick installation while maintaining stable electrical contact under vibration and frequent connection cycles.

The connector consists of a plug and matching receptacle with multiple keyway orientations to prevent incorrect mating during installation. Manufactured with precision-machined conductive contacts and a durable metal shell, it provides dependable electrical performance and mechanical protection in demanding operating environments. Compatible with corresponding Russian ОНЦ-БС-1(2) series connectors where specifications match, it is suitable for equipment maintenance, system upgrades, and new industrial applications.

Product Features

-- Compact 50-pin configuration for high-density electrical connections.

-- Bayonet coupling allows fast installation and secure locking.

-- Multi-key positioning helps prevent incorrect connector alignment.

-- Copper alloy contacts with gold or silver plating provide stable electrical conductivity.

-- Aluminum alloy shell with anodized treatment offers excellent corrosion resistance and mechanical durability.

-- Optional zinc alloy shell with nickel plating is available for enhanced surface protection.

-- Designed for repeated mating with reliable performance over multiple connection cycles.

Technology & Working Principle

The connector utilizes a precision bayonet coupling system that locks securely with a simple rotational movement, reducing installation time while maintaining consistent contact pressure. High-quality insulating materials isolate individual contacts to minimize electrical interference, while precision-plated contacts improve conductivity and reduce contact resistance throughout the service life of the connector.
