305-054-521-568

Edgeboard Connectors Overview

The EDAC Inc. 305-054-521-568 is a standard card edge connector designed for dual-edge PCBs. It features 54 positions with a 3.96 mm (0.156 inch) contact spacing and 3.56 mm row spacing. The connector accepts PCBs with a nominal thickness of 1.57 mm. Constructed with copper alloy contacts featuring gold plating, it supports a continuous current rating of 5 A and withstands 1800 VACrms. The insulator body is green thermoplastic polyester, operating between -40°C and +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features low-profile insulator body design for compact panel mounting
• Utilizes half-waffle contact type for reliable signal transmission

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring dual-edge card connections
• Industrial control systems utilizing standardized card edge interfaces
• Test and measurement equipment needing robust vertical interconnects

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required polarizing key configurations and flange characteristics. Confirm that the target PCB thickness falls within the specified acceptance range of 1.37 mm to 1.78 mm. Check RoHS compliance status against project requirements before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row female connector with 3.96 mm pitch is required for vertical panel installation. Ensure the application demands a 5 A current rating and operates within the -40°C to +105°C temperature range. Verify that the PCB design accommodates the 1.57 mm nominal thickness specification for proper mechanical fit.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles, all sharing common electrical specifications and contact spacing. The 305-054 variant specifically provides 54 positions, balancing density with manageable board footprint for dual-edge applications.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-054-521-202 and 305-054-556-278. These alternatives share identical positional and spacing parameters but may differ in insulator color or specific flange threading options. Validate mechanical dimensions before substitution.
