305-070-521-507

Edgeboard Connectors Overview

The EDAC Inc. 305-070-521-507 is a standard card edge connector from the 305 series, designed for panel mount applications with vertical orientation. It features 70 positions arranged in two rows with a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts and solder pin termination. It supports PCB thicknesses of 1.57 mm and operates within a temperature range of -40°C to +105°C. Rated for 5 A current, it offers 5 GOhms insulation resistance and includes M3 threaded inserts for secure mounting.

Edgeboard Connectors Procurement Notes

Verify RoHS compliance status through official manufacturer documentation prior to integration. Confirm that the specific ordering suffix matches the required contact plating and housing material specifications. Ensure compatibility with the target PCB thickness of 1.57 mm during mechanical design validation. Cross-reference the datasheet for any regional distribution restrictions or supply limitations.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 70-position interface with a 3.96 mm pitch is required. The vertical panel mount style suits applications where space constraints favor direct board insertion. Verify that the 5 A current rating and 105°C maximum operating temperature meet the system's electrical and thermal requirements. Consider the M3 mounting holes for secure attachment in vibration-prone environments.
