WF28 Aviation Connector Industrial Circular Power and Signal Plug

SF Series Aviation Connectors Specifications and Performance Data

WF28 Aviation Connector Overview

The WF28 Aviation Connector is a large-size threaded circular connector engineered for industrial power transmission and multi-signal control systems. Compared with smaller aviation plug models, the WF28 series offers a larger contact diameter and higher current-carrying capability, making it suitable for equipment requiring stable electrical performance and strong mechanical fixation.

It is commonly used in automation machinery, power distribution units, testing equipment, and industrial control cabinets.

Strong Threaded Coupling for Secure Locking

The WF28 aviation plug adopts a precision threaded locking mechanism to ensure firm mating between plug and socket. This design delivers several operational advantages:

• Anti-vibration performance in heavy machinery
• Stable retention under cable tension
• Reduced risk of accidental disconnection
• Clear mechanical engagement during installation

This locking structure makes the WF28 connector ideal for applications where stable long-term electrical connection is critical.

High Current Capacity with Larger Contact Structure

One of the core advantages of the WF28 circular connector is its larger internal contact design. Key structural features include:

• Increased contact diameter for improved conductivity
• Optimized contact spacing for electrical safety
• Support for higher rated current compared to smaller models
• Suitable for mixed power and signal transmission

The WF28 series can be configured for power circuits, motor interfaces, and control signal integration in a single connector body.

Durable Metal Shell for Industrial Protection

The connector housing is manufactured using a metal shell structure, providing:

• Mechanical strength against impact
• Basic EMI shielding capability
• Wear resistance in frequent connection cycles
• Long service life in factory environments

When properly installed, the WF28 aviation connector can meet industrial protection requirements depending on configuration and sealing design.

Multiple Contact Configurations

The WF28 connector is available in multiple contact arrangements to meet different wiring demands. Typical applications include:

• Industrial power input
• Equipment output interface
• Motor control wiring
• Automation signal routing

Contact quantity varies depending on engineering requirements. Custom layouts can be developed for OEM projects.

Flexible Termination and Mounting Options

To adapt to different installation methods, the WF28 series supports:

• Cable plug versions
• Panel mount receptacle versions
• Rear panel installation
• Solder termination
• Crimp termination (depending on structure)

This flexibility allows easy integration into control cabinets, distribution panels, and equipment housings.

Selection Considerations for WF28 Connectors

When evaluating the WF28 Industrial Circular Power & Signal Plug for your project, consider the following decision points:

• Pin count and layout: Confirm the number of cores required (2/3/4/5/7/9/12 pin options) and whether you need mixed power and signal contacts in one housing.
• Mating configuration: Determine whether you need a cable plug, panel mount receptacle, or a combination, and verify the male/female orientation for your application.
• Termination method: Select between solder and crimp termination based on your assembly process and field maintenance requirements.
• Environmental exposure: Assess vibration levels, moisture, and temperature range to confirm the threaded locking and metal shell provide adequate protection.
• Electrical load: Verify that the contact diameter and rated current match your power circuit demands before specifying the connector.

Application Boundaries

The WF28 series is well suited for industrial power input, motor control wiring, and automation signal routing in factory environments. However, it is not intended for submersible applications, high-flex robotic cable management, or installations requiring tool-free quick disconnect. For those requirements, consider alternative connector families with appropriate sealing and locking characteristics.
