305-040-500-508

Edgeboard Connectors Overview

The EDAC Inc. 305-040-500-508 is a standard card edge connector header featuring 40 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing with a row pitch of 3.56 mm (0.140 inch). Designed for panel mount installation at a vertical angle, the connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The contacts are constructed from copper alloy and feature gold plating to ensure reliable signal transmission. Rated for 5 A continuous current and 1800 VACrms insulation voltage, it 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 board alignment
• Features a low-profile insulator body made of thermoplastic material
• Supports solder lug termination for robust panel mounting

Edgeboard Connectors Applications

• Industrial control systems requiring high-current connections
• Telecommunications equipment backplanes
• Test and measurement instrumentation interfaces

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the manufacturer's official ordering guide to confirm exact housing color and terminal style variations. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Confirm that the required polarizing key options are sourced separately if mechanical locking is necessary for the application environment.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with a 3.96 mm pitch is required for panel-mounted applications. The 5 A current rating and 1800 VACrms insulation support demanding electrical environments. Verify that the vertical orientation aligns with the chassis design constraints and that the gold-plated contacts meet the corrosion resistance requirements for the operating conditions.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination styles while maintaining consistent 3.96 mm spacing. The 305-040-500-508 specifically denotes a 40-position dual-row header with solder lug termination, distinguishing it from surface-mount or single-row variants within the same product family.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include EDAC models 305-040-500-502 and 305-040-520-268, which share identical 40-position, 3.96 mm pitch specifications. Verify that alternative suffixes match the required termination type and housing material properties before substitution.
