Board edge straddle mount connections
Industrial control system interconnects

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm exact contact plating thickness and material specifications. Confirm that the required polarizing key type matches the connector's acceptance capabilities. Ensure the target printed circuit board thickness aligns with the 1.57 mm nominal requirement for proper mechanical engagement.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge header with a 3.96 mm pitch is required for panel-mounted systems. Consider the 5 A continuous current rating and 1800 VACrms insulation voltage for electrical safety margins. Verify compatibility with existing polarizing key requirements and ensure the mounting style fits the chassis design constraints.
