305-046-521-258

Edgeboard Connectors Overview

The EDAC Inc. 305-046-521-258 is a standard card edge connector featuring 46 positions arranged in two rows. It utilizes a 3.96 mm (0.156 inch) contact spacing with a 3.56 mm row pitch. Designed for dual-edge female connections, the unit accepts printed circuit boards with a nominal thickness of 1.57 mm. The contacts are constructed from copper alloy and finished with gold plating to ensure reliable signal transmission. This component supports a continuous current rating of 5 A and offers an insulation resistance voltage capability of 1800 VACrms.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact pin count, termination style, and material specifications. Ensure compatibility with the target PCB thickness of 1.57 mm and verify that the 3.96 mm pitch aligns with the system layout requirements before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this model when a high-current 5 A rating and 1800 VACrms insulation strength are required for vertical panel installations. The dual-edge female design is suitable for applications needing stable mechanical retention of thick PCBs. Consider the low-profile body if space constraints exist within the enclosure assembly.
