305-070-521-578

Edgeboard Connectors Overview

The EDAC Inc. 305-070-521-578 is a standard card edge connector from the 305 series, designed for panel mounting with vertical orientation. It features 70 positions arranged in two rows with a contact spacing of 3.96 mm (0.156 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm. Contacts are made of copper alloy and gold-plated, supporting a continuous current rating of 5 A. The termination type is solder pin, and the insulator body is constructed from thermoplastic polyester.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body for compact installation
• Supports dual female contacts for reliable signal transmission

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Medical equipment needing high-reliability connections
• Agricultural technology applications in harsh environments

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required polarizing keys and board thickness specifications. Confirm that the manufacturer's standard lead time aligns with project schedules, as production cycles may vary. Ensure compliance with RoHS and REACH regulations if applicable to your region. Cross-reference the datasheet for precise mechanical dimensions before integration into the design.

Edgeboard Connectors Selection Notes

Select this model when a 70-position interface with 3.96 mm pitch is required for vertical panel mounting. Consider the 5 A current rating and gold plating for durability in demanding environments. Verify that the target PCB thickness falls within the acceptable range for optimal contact engagement. Compare against other series members if different row counts or spacings are needed.
