LD20/SP20 Heavy-Duty Square Connector Dimensions and Specs
WF16 Heavy-Duty Circular Connector for Industrial Power and Signal Transmission
The WF16 heavy-duty circular connector provides reliable electrical connections for industrial power and signal transmission. Its robust metal housing and stable contact structure support long-term performance in demanding environments, making it a practical choice for machinery, automation equipment, control systems, and electrical installations where secure connections are essential.

Durable Construction for Harsh Industrial Environments
The WF16 connector features a rugged metal shell that provides mechanical strength and durability. This design protects internal contacts and supports reliable performance under vibration or frequent connection cycles. The housing is made of zinc alloy with nickel plating, offering corrosion resistance for industrial settings.
Stable Power and Signal Transmission
Engineered for dependable electrical performance, the WF16 connector supports both power and signal transmission. Its precision contacts—brass with gold plating—ensure stable conductivity and help reduce signal loss, making it suitable for various industrial applications.
Secure Threaded Locking Mechanism
The connector uses a threaded locking mechanism that provides a firm, secure connection. This structure helps prevent accidental disconnection and ensures reliable operation in equipment and machinery.

Selection Considerations for WF16 Connectors
When selecting a WF16 connector for your application, consider the following decision points:
-
Pin count: Available in 2 to 10 pin configurations; choose based on the number of circuits you need to connect.
-
Gender: Male and female versions are available; confirm which side mounts to the cable or panel.
-
Environmental exposure: The metal housing suits industrial environments, but verify whether your installation requires additional sealing or protection.
-
Mating requirements: Confirm the mating connector type and locking style to ensure compatibility with your existing system.
Where WF16 Connectors Fit—and Where They Don't
WF16 connectors are well suited for industrial machinery, automation systems, and control panels where robust metal construction and secure threaded locking are beneficial. They are less suitable for applications requiring high-density pin counts beyond 10 positions, or where a lightweight plastic housing is preferred. For applications needing higher pin density, consider other connector series such as the 12G Series Circular Connectors.
