305-050-555-504

Edgeboard Connectors Overview

The EDAC Inc. 305-050-555-504 is a dual-edge female card edge connector from the 305 series, designed for board-to-board or panel mounting applications. It features 50 positions arranged in two rows of 25 contacts with a 0.156-inch (3.96mm) spacing. The connector utilizes gold-plated copper alloy semi-crimped terminals and a green thermoplastic polyester insulator. It supports PCB thicknesses between 0.054 and 0.070 inches and operates within a temperature range of -40°C to 105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure alignment
• Provides reliable electrical connection via gold-plated semi-crimped terminals
• Features a robust thermoplastic polyester housing for environmental stability

Edgeboard Connectors Applications

• High-density electronic assembly interconnects
• Industrial control system backplanes
• Telecommunications equipment signal routing

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required contact count and pitch specifications for your design. Confirm compliance with RoHS3 standards if restricted substances are prohibited in your manufacturing process. Ensure the selected variant aligns with the intended mounting style and thermal requirements of the final application.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female configuration with 50 positions is required. Consider the 0.156-inch pitch and compatible PCB thickness range during mechanical design. Evaluate the need for polarizing key compatibility if precise board orientation is critical for the assembly process.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting options, providing versatile solutions for interconnect needs. The 305-050-555-504 specifically addresses applications requiring high pin counts with durable gold plating and stable insulation properties.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 305-050-556-502 and 305-050-556-504. Verify flange diameter differences, as these variants may have distinct mounting hole dimensions compared to the 555 suffix model.
