GOST OHS Series Circular Connector for Automotive Vehicles

GOST OHS Circular Connector with Multiple Core Count Options

GOST OHS Series Connector for Automotive Vehicle Systems

The OHS Series Russian Standard Connectors are designed for automotive vehicle systems across Russia and the CIS regions, supporting commercial vehicles, off-road trucks, electric vehicles (EVs), and specialized automotive equipment. These connectors address the operational demands of automotive environments, including vibration, temperature fluctuations, dust, moisture, and mechanical stress. Manufactured to Russian GOST standards, they are intended to integrate with native automotive systems for stable power and signal transmission.

Key Selection Considerations for Automotive Applications

When evaluating the OHS Series for your vehicle platform, consider the following decision points:

• Core count and configuration: Available in 4 to 50 pins with male or female gender options, allowing matching to your specific wiring architecture.
• Environmental exposure: The aluminum alloy housing and PPS/PEI insulators are selected for resistance to temperature extremes, vibration, and automotive fluids.
• Mating and locking requirements: The bayonet coupling system provides a quarter-turn locking action designed to resist vibration-induced disconnection.
• Contact plating needs: Brass contacts with silver or gold plating options support different signal integrity and corrosion resistance requirements.
• Temperature operating range: Rated for -60°C to +200°C, suitable for engine bay and exterior mounting locations.

Construction and Material Properties

The OHS Series uses an aluminum alloy housing for structural strength and weight management. The insulator material is PPS or PEI, selected for thermal stability and electrical insulation performance. Contact cores are machined from brass and plated with silver or gold, depending on the application's conductivity and corrosion resistance needs. The bayonet locking system enables tool-free mating and is designed to maintain connection integrity under vibration.

Application Scope and Boundaries

Suitable applications include:

• Commercial trucks, buses, and delivery vehicles
• Off-road vehicles and construction equipment
• Electric and hybrid vehicle power and signal circuits
• Vehicle sensor systems and telematics
• Automotive aftermarket upgrades and maintenance

Applications requiring additional verification:

• Submersible or continuously submerged environments – confirm sealing requirements with your application data
• High-vibration rotating assemblies – validate with application-specific testing
• Direct exposure to concentrated industrial chemicals – verify chemical compatibility

Electrical Performance and Installation Planning

The connector's contact design and insulation materials support consistent signal integrity and power transmission for vehicle functions. For installation planning, consider the following:

• Confirm the required pin count and gender configuration against your wiring harness layout
• Verify that the bayonet coupling orientation matches your mounting access constraints
• Plan for the operating temperature range relative to the mounting location
• Confirm contact plating selection based on your signal type and environmental exposure

Quality and Testing Considerations

The OHS Series is manufactured with attention to dimensional consistency and mating reliability. The anti-vibration locking mechanism and precision alignment pins are designed to prevent misinsertion and accidental disengagement. For quality assurance in your application, request test data relevant to your specific environmental and mechanical requirements.

Customization and OEM Options

Standard models are available from stock. For vehicle-specific requirements, ODM/OEM customization options may be discussed with our engineering team. Provide your wiring diagram, mounting constraints, and environmental specifications to evaluate feasibility.
