WF Series Circular Connectors for Railway Signaling and Control Systems

GOST OHS Circular Connector with Multiple Core Count Options

WF Series Circular Connectors for Railway Signaling and Control Systems

Railway signaling and control systems demand connections that withstand continuous vibration, temperature extremes, and strict safety oversight. The WF Series circular connectors are engineered for these conditions, offering a choice of core counts and termination methods to match the electrical and mechanical requirements of transit applications.

Model Range and Core Count Selection

The WF Series includes WF12, WF16, WF20, and WF24 models, with core counts from 2 to 32 pins. This range allows you to match the connector to the signal density of your specific subsystem, from simple power links to multi-channel control wiring.

Key Decision Points for Rail Applications

Environmental and Mechanical Durability

WF Series connectors operate across a wide temperature range, from -55°C to +125°C, using insulation materials such as PA66, PBT, or PEI. The housing is available in nickel-plated brass or stainless steel, with an epoxy-coated insulator to resist humidity and chemical exposure common in rail environments.

Configuration Flexibility

Choose from 4-core configurations for lighting circuits up to 32-core layouts for door control units or sensor arrays. Termination options include crimp, weld, or screw connections, all secured with anti-loosening threaded locking to prevent disconnection under vibration.

Installation and Space Constraints

The compact shell design suits tight spaces in on-board panels, ticket terminals, and trackside signal boxes. Before selecting a model, confirm the available panel cutout and mating clearance in your enclosure.

Application Scope and Boundaries

Suitable for:

• On-board systems: door controls, brake sensor arrays, HVAC regulation, passenger information systems, and traction signal links.
• Trackside equipment: signal transceiver connections, switch point monitors, track condition sensors, and power distribution units.
• Passenger-facing devices: in-train video surveillance, Wi-Fi access points, and broadcast system wiring.

Not suitable for: applications requiring continuous submersion, explosive atmospheres, or direct exposure to aggressive chemicals without additional protective enclosures. Confirm your specific environmental class before specifying.

Quality Validation and Customization

Each WF Series connector is subject to 500+ mating cycle testing and pre-shipment validation. For specialized needs, custom core counts, high-temperature PEI insulation, and cable lengths can be arranged. Contact the rail transit solutions team to request a sample or quote based on your system requirements.

Information to Include in Your Inquiry

To receive an accurate matching recommendation, please provide:

• Required core count and gender (male/female) for each connection point.
• Cable diameter and conductor cross-section for termination planning.
• Operating temperature range and any exposure to moisture, vibration, or chemicals.
• Panel cutout dimensions and mounting style (bulkhead, cable, or PCB).
• Applicable standards or customer specifications for the project.
