305-038-521-201

Edgeboard Connectors Overview

The EDAC Inc. 305-038-521-201 is a dual-edge female card edge connector designed for vertical panel and through-hole mounting. It features 38 positions with a 0.156-inch (3.96mm) pitch across two rows. The connector utilizes gold-plated copper alloy contacts with a 10.0µin thickness and half-bellows contact type. It accommodates board thicknesses of 0.054 to 0.070 inches (1.37 to 1.78mm). The housing is green thermoplastic polyester, rated for -40°C to 105°C operation.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration for non-specified dual-edge cards
• Gold-plated half-bellows contacts for reliable signal transmission
• Vertical panel mount design with solder termination
• Thermoplastic polyester insulation for thermal stability

Edgeboard Connectors Applications

• Industrial control system backplanes
• Medical device interconnects
• Agricultural technology equipment modules
• General-purpose circuit board expansion slots

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC 305 Series Ordering Guide to ensure correct pin count, pitch, and termination style match your design requirements. Confirm RoHS3 compliance status and check for any regional distribution restrictions or lead time variations prior to finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female interface with a 0.156-inch pitch is required for vertical panel installation. Ensure the target PCB thickness falls within the 0.054 to 0.070-inch range. Consider the operating temperature limits and material compatibility with the mating card edge for long-term reliability in the intended environment.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and pitch options for diverse interconnect needs. The 305-038 variant specifically provides 38 positions, balancing density and spacing for standard dual-edge applications in robust industrial and commercial hardware designs.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series parts for different position counts or pitches. Verify mechanical dimensions and electrical ratings against alternative manufacturers' offerings to ensure direct functional substitution without redesigning the host PCB layout.
