Edgeboard Connectors datasheet and documents for 305-020-555-504

305-020-555-504

Edgeboard Connectors Overview

The EDAC Inc. 305-020-555-504 is a standard card edge connector featuring 20 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing and accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The connector employs gold-plated copper alloy contacts for reliable signal transmission and includes a green thermoplastic polyester insulator body. Designed for panel mounting, it supports vertical installation and offers a continuous current rating of 5 A.

Edgeboard Connectors Feature Summary

Accepts between-contact and in-contact polarizing keys for secure board alignment
Features a low-profile insulator body to minimize overall assembly height
Provides robust electrical performance with a 5 A continuous current rating

Edgeboard Connectors Applications

Panel-mounted electronic assemblies requiring secure card edge interfaces
Industrial control systems utilizing standardized PCB modules
Communication equipment needing reliable dual-edge connector solutions

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure compatibility with required polarizing key configurations and insulation material specifications. Confirm that the target application environment remains within the specified operating temperature range and voltage ratings to maintain long-term reliability and safety compliance.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with a 3.96 mm pitch is required for panel-mount applications. Ensure the host PCB thickness matches the 1.57 mm design specification. Consider the availability of compatible polarizing keys if mechanical locking or precise alignment is necessary for the specific system integration requirements.
