GOST PC Series Circular Connectors for Russian-Standard Equipment

The GOST PC Series Circular Connectors are designed as a direct-fit solution for industrial equipment built to Russian and CIS standards. This connector family uses a durable metal shell and supports a wide operating temperature range, making it suitable for environments from arctic cold to industrial heat. The modular contact system allows configuration of power, signal, and ground contacts within a single, vibration-resistant housing.

Key Selection Criteria for PC Series Connectors

When choosing a PC Series connector, consider the following decision points to ensure a correct match for your application:

• Contact Configuration: The modular system (Type1/2/3) supports flexible mixing of power and signal contacts. Confirm the required pin count and arrangement for your specific wiring scheme.
• Environmental Protection: Options range from IP50 to IP68, including hermetic versions. Select the ingress protection level based on the actual operating environment—whether the connector will face dust, moisture, or pressure variations.
• Mechanical Durability: The aluminum alloy shell with EMI shielding is built to withstand shock, vibration, and corrosion. Verify the mechanical requirements of your mounting and cable strain relief.
• Termination Method: Gold-plated crimp contacts provide stable, low-resistance performance. Ensure your installation process supports proper crimping tools and quality checks.

Understanding the Modular Contact System

The PC Series uses a modular contact system that allows you to combine power (up to 20A), signal, and ground contacts within a single housing. This flexibility is useful for equipment that requires mixed power and control lines in one connection point. The screw locking system provides a secure mechanical connection, and the housing material—aluminum alloy with oxidation treatment—offers corrosion resistance for industrial settings.

Suitable and Unsuitable Applications

Suitable for: Industrial machinery, control systems, and equipment designed to Russian-standard specifications where direct-fit replacement is needed. The wide temperature range and IP protection options make it adaptable to harsh environments.

Unsuitable for: Applications requiring high-density micro-miniature connections, or environments where the specific IP rating and temperature range of the chosen variant do not meet the actual conditions. Always verify the exact IP rating and temperature limits for your selected configuration, as these vary by model.

Installation and Mating Considerations

Before installation, confirm the mating-side connector type (male/female) and the pinout arrangement. The connector uses a screw locking system, so ensure the mating threads are compatible. For cable assembly, verify the cable outside diameter and conductor size against the connector's cable range to achieve a proper seal and strain relief. If you are replacing an existing connector, provide the original part number or a clear drawing to confirm direct-fit compatibility.

Inquiry Checklist for Accurate Quotation

To receive an accurate quotation and technical confirmation, please provide the following details:

• Required pin count (e.g., 4, 7, 10, 19, 32, 50) and gender (male/female)
• Mating-side connector type and pinout or wiring diagram
• Cable outside diameter and conductor size (AWG/mm²)
• Electrical load (current and voltage) per contact
• Required IP protection level and operating temperature range
• Mounting style (cable, panel, or flange) and any specific mechanical requirements
• Order quantity and target delivery timeline
