OHS Series Russian Standard Connectors for Rail Transit Applications

GOST OHS Circular Connector with Multiple Core Count Options

OHS Series Russian Standard Connectors for Rail Transit

The OHS Series Russian Standard Connectors are engineered for high-performance rail transit applications, providing reliable and durable electrical connections in trains, metros, and light rail systems. Designed to meet stringent Russian GOST standards, OHS connectors ensure safety, stability, and long-term reliability in demanding transportation environments.

Key Models and Selection Guidance

Selecting the right OHS connector depends on your circuit requirements and installation space. The series offers multiple core count options to match different rail transit subsystems:

• OHS-2 – Compact connector suitable for control circuits and signaling systems where space is limited.
• OHS-4 – Medium-capacity connector ideal for power distribution and onboard electronics requiring balanced current handling.
• OHS-6 – High-capacity connector for heavy-duty traction systems and industrial equipment demanding higher current ratings.

When choosing between models, consider the number of cores needed, the current rating of your application, and the available mounting space in your equipment enclosure.

Construction and Environmental Performance

The OHS Series uses an aluminum alloy housing with a quick bayonet lock system, allowing efficient installation and maintenance in tight rail compartments. The insulator is made from PPS material, while the brass contacts are plated with silver or gold for stable conductivity. The operating temperature range of -60°C to +85°C supports use across varied climatic conditions encountered in rail networks.

Application Scope and Boundaries

These connectors are suited for rolling stock electrical systems, including control circuits, signaling, power distribution, and onboard electronics. They are appropriate for trains, subways, and trams operating under vibration and temperature variation.

However, OHS connectors are not designed for submersion or continuous exposure to standing water. For applications requiring protection against moisture ingress, verify the specific IP rating of your chosen configuration with our engineering team before installation.

Buyer Decision Checklist

To ensure the correct OHS connector configuration for your project, prepare the following information before inquiry:

• Required number of cores and pin arrangement
• Gender (male or female) and mounting style (cable or panel)
• Operating current and voltage for your specific circuit
• Cable diameter and termination requirements
• Environmental conditions, including temperature range and exposure to moisture or chemicals

For detailed technical specifications including rated current, voltage, and contact dimensions, refer to the Technical Specifications section.
