305-076-520-504

Edgeboard Connectors Overview

The EDAC 305-076-520-504 is a standard card edge connector from the 305 series, designed for panel mounting applications. It features a dual-row configuration with 76 positions and a contact spacing of 3.96 mm (0.156 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Electrical specifications include a continuous current rating of 5 A and an insulation resistance of 5 GOhms. The operating temperature range spans from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure alignment
• Features a low-profile insulator body constructed from thermoplastic polyester
• Utilizes gold-plated copper alloy contacts for reliable signal transmission

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interconnects
• Communication equipment utilizing standard thickness PCBs
• Automotive electronics modules needing high thermal stability

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the official EDAC ordering guide to ensure correct pin count, row configuration, and termination style. Confirm that the required polarizing key type matches the connector's acceptance specifications. Cross-reference the board thickness tolerance with the component's design limits to guarantee mechanical fit.

Edgeboard Connectors Selection Notes

Select this component when a vertical panel mount solution is required for double-sided edge cards. Ensure the application environment stays within the specified -40°C to +105°C operational range. Verify that the PCB thickness aligns with the 1.57 mm nominal requirement for proper contact engagement.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its compatibility with .062 inch thick boards and offers various position counts. The 305 series supports both receptacle and header configurations, providing flexibility for different assembly orientations.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 series ordering guide for alternative part numbers with matching position counts and row configurations. Verify that any substitute maintains the same 3.96 mm pitch and panel mount installation style.
