305-038-521-508

Edgeboard Connectors Overview

The EDAC Inc. 305-038-521-508 is a standard card edge connector from the 305 series, designed for panel mount applications with vertical orientation. It features 38 positions arranged in two rows with a 3.96 mm (0.156 inch) pitch. The connector utilizes gold-plated copper alloy contacts and a thermoplastic housing. It supports solder pin termination and accommodates board thicknesses of 1.57 mm. Rated for 5 A continuous current, it operates within a temperature range of -40°C to +105°C and offers an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Dual-row configuration providing 38 contact positions for high-density interconnects
• Gold-plated copper alloy contacts ensure reliable signal transmission and corrosion resistance
• Thermoplastic housing provides structural integrity and electrical insulation
• Vertical panel mount design facilitates secure installation on chassis panels

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interfaces
• Telecommunications equipment utilizing dual-edge card connections

Edgeboard Connectors Procurement Notes

Verify the exact part number against official manufacturer documentation to confirm compatibility with your system requirements. Ensure that the specified pitch, row count, and termination type match your PCB design. Check for RoHS compliance status if environmental regulations apply to your project. Confirm availability through authorized distributors as supply levels may vary.

Edgeboard Connectors Selection Notes

Select this component when a 38-position, dual-row card edge connector is required for panel mounting. The 3.96 mm pitch must align with the mating card edge specifications. Consider the 5 A current rating and operating temperature range to ensure suitability for the intended electrical load and environmental conditions. Verify that the vertical orientation fits the mechanical constraints of the enclosure.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which includes various configurations of standard card edge connectors. The series is characterized by its use of thermoplastic housings and gold-plated contacts. Other models in the series differ primarily in position count, such as 14, 18, or 48 positions, while maintaining similar electrical ratings and mounting styles.

Edgeboard Connectors Replacement Considerations

Compatible substitutes within the same series include EDAC 305-038-521-502 and 305-038-521-508 variants with different suffixes indicating minor packaging or material differences. Cross-series replacements require verification of pitch, row count, and current rating to ensure functional equivalence.
