Product Specification

• OHS Series 50 Pin Bayonet Circular Receptacle Male Connector Industrial Panel Mount

  Product Overview

  The OHS Series 50 Pin Bayonet Circular Receptacle is a compact industrial connector developed using advanced Russian connector technology for reliable signal and power transmission in demanding electrical systems. The connector features a 50-pin male contact configuration housed in a durable anodized aluminum alloy shell. Its multi-key positioning design prevents incorrect mating during installation, while the bayonet locking mechanism provides quick connection and dependable mechanical retention. Designed to be compatible with the Russian ОНS-BС-1(2) series, the OHS series offers convenient replacement and interchangeability for equipment upgrades and maintenance without requiring major system modifications.

  Product Features

  • Compact circular connector designed for high-density signal transmission.

  • Bayonet locking mechanism provides fast installation and secure mechanical connection.

  • Multi-key positioning minimizes incorrect insertion and improves assembly efficiency.

  • Compatible with Russian ОНS-BС-1(2) series connectors for replacement applications.

  • Gold- or silver-plated copper alloy contacts provide stable conductivity and corrosion resistance.

  • Industrial-grade anodized aluminum alloy shell offers excellent durability and environmental protection.

  • PPS insulating material provides reliable electrical insulation and thermal stability.

  • Suitable for repeated mating operations with a mechanical life of up to 250 insertion and removal cycles.

  Operating Principle

  The connector establishes electrical continuity through precision-machined male contacts that engage with the corresponding female connector. The bayonet coupling secures the connector with a simple twist-lock action, while the multi-key alignment system ensures correct orientation before mating. This design maintains consistent contact pressure, helping to achieve stable signal transmission and dependable electrical performance even in environments exposed to vibration and mechanical movement.
