305-056-555-508

Edgeboard Connectors Overview

The EDAC Inc. 305-056-555-508 is a standard card edge connector from the 305 series, designed for dual-edge insertion. It features 56 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). It utilizes gold-plated copper alloy contacts rated for 5 A current. The housing is green thermoplastic, and it supports panel mounting with vertical orientation.

Edgeboard Connectors Procurement Notes

Verify the specific suffix code to confirm flange features and mounting hardware compatibility. Ensure the target application requires the 3.96 mm pitch specification. Confirm that the operating temperature range of -40°C to +105°C meets environmental requirements. Check for RoHS compliance status if restricted substances are a concern. Validate that the 5 A current rating is sufficient for the intended load.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge card edge connector with a 3.96 mm pitch is required. Consider the 56-position count for I/O density needs. Choose based on the need for panel-mounting stability in vertical orientations. Verify that the PCB thickness matches the 1.57 mm acceptance criteria. Evaluate the gold plating requirement for corrosion resistance.

Edgeboard Connectors Part Context
