305-078-555-201

Edgeboard Connectors Overview

The EDAC Inc. 305-078-555-201 is a standard card edge connector from the 305 series, designed for dual-edge board insertion. It features 78 positions with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Constructed with copper alloy contacts featuring gold plating, it utilizes a thermoplastic insulator body. The component supports panel mounting in a vertical orientation and employs solder lug termination for secure electrical connection.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm exact termination style and flange options. Confirm RoHS compliance status and environmental ratings prior to integration. Ensure that the selected variant matches the required PCB thickness tolerance and mounting hardware specifications for the target application chassis.

Edgeboard Connectors Selection Notes

Select this component when a high-density dual-edge interface with 3.96 mm pitch is required for panel-mounted applications. Consider the 1.57 mm board thickness compatibility and vertical orientation constraints. Evaluate the gold contact plating requirements for corrosion resistance and the thermoplastic housing durability against operational temperature ranges specified in the official documentation.
