305-076-555-508

Edgeboard Connectors Overview

The EDAC Inc. 305-076-555-508 is a standard card edge connector designed for panel mounting in a vertical orientation. It features a dual female configuration with 76 positions and a contact spacing of 3.96 mm (0.156 inches). The row spacing measures 3.56 mm (0.140 inches), accommodating printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). The contacts are constructed from copper alloy and finished with gold plating to ensure reliable signal transmission. This component supports a continuous current rating of 5 A and withstands up to 1800 VACrms.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body made of thermoplastic material
• Provides high insulation resistance rated at 5 GOhms

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standardized backplane connections
• Test and measurement instrumentation needing reliable vertical panel mounts

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact termination style and plating specifications. Ensure that the required polarizing key accessories are ordered separately if mechanical locking is necessary for the application. Confirm compliance with RoHS directives by checking the latest manufacturer release notes before final procurement integration.

Edgeboard Connectors Selection Notes

Select this model when a dual-row, 76-position interface is required for 1.57 mm thick PCBs. The 3.96 mm pitch distinguishes it from finer pitch alternatives. Consider the vertical panel mount style for chassis integration. Verify that the 5 A current rating meets the electrical load requirements of the target circuit design.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination options while maintaining consistent dimensional standards. The 305-076 variant specifically addresses applications needing higher density interconnects within the 0.156 inch pitch family.

Edgeboard Connectors Replacement Considerations

Cross-reference part numbers such as 305-076-556-508 or 305-076-555-503 for alternative termination styles or slight dimensional variations. Verify that substitute parts maintain the same 76-position count and 3.96 mm pitch compatibility.
