Selection Guidance and Inquiry Checklist
When selecting a WS20 connector for your application, consider the following decision points:
-
Pin count and layout: Confirm the number of cores required and whether the pin assignment matches your mating connector.
-
Gender and mounting: Determine whether male or female contacts are needed and if the connector will be panel-mounted or cable-to-cable.
-
Cable specification: Verify the required cable length, conductor size, jacket material, and whether shielding is necessary for your signal integrity.
-
Environmental conditions: Assess the operating temperature, exposure to moisture or chemicals, and vibration levels to confirm the connector's suitability.
-
Electrical load: Ensure the rated current and voltage of the selected pin configuration meet your system requirements.
For a broader view of compatible options, review the Aviation Plug Connectors catalog to compare series and configurations.
When to Choose This Connector
The WS20 pre-wired assembly is well suited for equipment manufacturers seeking a ready-to-install connection solution with consistent quality. It is also appropriate for field replacements where on-site wiring is impractical or error-prone.
When to Consider Alternatives
If your application requires a higher IP rating for submersion, a different locking mechanism, or a specific certification not listed here, confirm the final configuration with our engineering team before ordering. The WS20 may not be the optimal choice for extreme temperature ranges or specialized chemical exposure without verified material compatibility.
