305-042-520-504

Edgeboard Connectors Overview

The EDAC Inc. 305-042-520-504 is a standard card edge connector from the 305 Series, designed for panel mount installation with a vertical orientation. It features a dual female configuration with 42 positions arranged in two rows of 21 contacts each. The connector utilizes a 0.156-inch (3.96 mm) pitch and supports board thicknesses ranging from 0.054 to 0.070 inches (1.37 mm to 1.78 mm). Contact plating consists of gold over a copper alloy base, ensuring reliable electrical performance within an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual female contact configuration provides secure mating with double-sided card edge boards.
• Gold-plated copper alloy contacts ensure durable conductivity and corrosion resistance.
• Panel mount design with flange features facilitates stable mechanical integration.

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Communication equipment signal routing
• Automotive electronics module connections

Edgeboard Connectors Procurement Notes

Verify that the specific suffix matches the required flange and termination specifications, as variations exist within the 305 series. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure compatibility with the target PCB thickness range of 1.37 mm to 1.78 mm to guarantee proper mechanical fit and electrical contact integrity during assembly.

Edgeboard Connectors Selection Notes

Select this component when a high-density dual-row interface is required for vertical panel mounting. The 3.96 mm pitch accommodates larger gauge traces compared to finer pitches. Verify that the housing material, typically thermoplastic polyester, meets the thermal requirements of the application environment. Consider the half-beamlet contact type for reliable insertion and extraction cycles in industrial settings.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, a line of standard card edge connectors known for their versatility in various electronic assemblies. The series offers multiple position counts and configurations to suit different board sizes. The 305-042 variant specifically addresses applications needing 42 connection points in a compact dual-row format, balancing density with mechanical stability.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with identical 42-position dual female configurations, such as 305-042-520-202 or 305-042-520-268, provided the specific flange and termination details align with the design requirements. Cross-referencing dimensional drawings is essential to ensure mechanical interchangeability.
