• Agricultural technology hardware in harsh environments
• General-purpose electronic board-to-board or backplane connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct contact plating thickness and housing color specifications. Confirm RoHS compliance status and REACH restrictions prior to integration. Check for regional distribution limitations as availability may vary by supplier region. Ensure the selected variant matches the required PCB thickness tolerance of 1.57 mm for proper mechanical fit.

Edgeboard Connectors Selection Notes

Select this component when a vertical panel-mount card edge connector with 58 positions is required. The 3.96 mm pitch and dual-row layout suit applications needing moderate density. Verify that the target PCB thickness falls within the acceptable range of 1.37 mm to 1.78 mm. Consider the 5 A current rating and -40°C to +105°C operating temperature for environmental compatibility.
