305-050-500-208

Edgeboard Connectors Overview

The EDAC Inc. 305-050-500-208 is a standard card edge connector from the 305 series, designed for dual-row applications with 50 positions. It features 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 utilizes copper alloy contacts with gold plating and employs a solder lug termination type. Rated for 5 A continuous current and 1800 VACrms insulation voltage, it operates within a temperature range of -40°C to +105°C. The housing is constructed from thermoplastic material.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body for compact panel mounting
• Provides high dielectric strength with 1800 VACrms insulation rating

Edgeboard Connectors Applications

• Panel-mounted electronic interconnect systems
• Industrial control board connections
• Telecommunications equipment backplanes

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the official EDAC ordering guide to ensure correct termination style and mounting configuration. Confirm that the required polarizing key specifications match the connector design. Check RoHS compliance status directly on the manufacturer datasheet as regulatory requirements may vary by region. Ensure the target PCB thickness falls within the specified 1.57 mm tolerance for reliable contact engagement.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with 3.96 mm pitch is required for panel installation. The 50-position count suits moderate-density signal routing. Verify that the 5 A current rating meets the application's electrical load requirements. Consider the solder lug termination if through-hole mounting to a chassis or panel is preferred over surface mount methods.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, which offers various mounting options and position counts. The series is characterized by its robust thermoplastic construction and standardized 3.96 mm spacing. Similar models in the series differ primarily in the number of positions and specific termination variations, allowing for scalable design integration across different hardware platforms.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants such as 305-050-520-208 for alternative termination styles. Ensure any substitute maintains the same 3.96 mm pitch and 50-position count. Verify compatibility with existing polarizing key requirements and panel mounting constraints before substitution.
