305-050-555-508

Edgeboard Connectors Overview

The EDAC Inc. 305-050-555-508 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 50 positions arranged in two rows with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.140 inches (3.56 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Electrical specifications include a current rating of 5 A and an insulation resistance of 5 GOhms. The contacts are made of copper alloy with gold plating, housed in a green thermoplastic insulator. Operating temperature ranges from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row configuration providing 50 positions for high-density interconnects
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Low-profile insulator body designed for space-constrained panel installations

Edgeboard Connectors Applications

• Panel-mounted electronic systems requiring vertical connection
• Industrial control units utilizing dual-edge card modules
• Communication equipment interfaces needing robust thermal performance

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact mechanical dimensions and termination style. Ensure compatibility with the target PCB thickness of 1.57 mm. Confirm that the gold plating specification meets the required environmental durability standards for the intended operational environment before finalizing procurement.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with a 3.96 mm pitch is required for panel mounting. The 50-position count supports moderate I/O density. Verify that the straddle mount or board edge installation method aligns with the chassis design. Ensure the operating temperature range of -40°C to +105°C covers the application's thermal profile.

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 options. The 305-050-555-508 specifically denotes a 50-position dual-row variant with gold contacts and a thermoplastic housing. It is categorized under headers and edgeboard connectors within the interconnect components family.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series parts having identical 3.96 mm pitch and 50 positions. Verify mechanical fit and electrical ratings against alternative manufacturers' dual-row card edge connectors. Ensure substitute parts support the same 1.57 mm board thickness and panel mounting requirements.
