305-074-555-503

Edgeboard Connectors Overview

The EDAC Inc. 305-074-555-503 is a dual-edge female card edge connector designed for vertical panel mounting. It features 74 positions with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.140 inches (3.56 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Constructed with copper alloy contacts finished with gold plating, it utilizes a low-profile thermoplastic insulator body. The component operates within a temperature range of -40°C to +105°C and supports a current rating of 5 A per contact.

Edgeboard Connectors Procurement Notes

Verify the specific pin count and spacing against the target PCB layout before ordering. Confirm that the receiving board thickness aligns with the 0.062-inch nominal requirement for proper mechanical engagement. Ensure the selected variant matches the required operating temperature range and current capacity for the intended application environment. Cross-reference the manufacturer's latest datasheet to confirm compliance with RoHS3 standards and availability status.

Edgeboard Connectors Selection Notes

Select this model when a high-density dual-edge connection is required for vertical panel integration. The 0.156-inch pitch allows for substantial signal routing compared to finer pitches. Consider the 5 A current rating for power distribution needs alongside signal lines. The green color coding aids in visual identification during assembly. Verify compatibility with existing tooling for panel-mounted installations.

Edgeboard Connectors Part Context
