Edgeboard Connectors Procurement Notes

Verify the exact shaft type, keying, and termination style against your assembly drawings before ordering. Confirm that the voltage and current ratings meet the specific load requirements of your application circuit. Ensure the panel thickness accommodates the mounting hardware specifications provided in the official datasheet. Cross-reference the part number suffixes to confirm material and environmental rating compliance.

Edgeboard Connectors Selection Notes

Select this component based on the required number of poles and throws for your circuit logic. Consider the mechanical life expectancy and environmental sealing needs if operating in harsh conditions. Verify compatibility with existing panel cutouts and shaft drive mechanisms. Review the electrical ratings to ensure they exceed the maximum expected load under all operating conditions.

Edgeboard Connectors Part Context

This rotary switch belongs to EDAC's standard series of panel-mounted switches. These components are widely used in sectors requiring manual selection of operational modes or circuit paths. The 305 series is known for its reliability and standardized form factors, allowing for straightforward replacement in legacy systems.
