Overview

The EDAC Inc. 306-028-521-158 is a dual-edge female card edge connector featuring 56 positions with a 0.156-inch (3.96mm) pitch. It utilizes a single centerline row of contacts and accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). The component employs gold-plated cantilever spring contacts for reliable signal transmission. Designed for panel mounting, it features a low-profile insulator body constructed from thermoplastic polyester. The unit operates within a temperature range of -40°C to 105°C and complies with RoHS3 standards.

Feature Summary

Dual-edge female configuration with cantilever spring contacts for secure board retention
Single centerline contact row design accommodating standard 0.062 inch PCB thickness
Gold-plated terminals ensure corrosion resistance and stable electrical performance
Low-profile thermoplastic polyester insulator body supports compact panel installations

Applications

Industrial control system interconnections
Medical device internal circuitry
Telecommunications equipment backplanes
Consumer electronics module interfaces

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current catalog to confirm exact pin count, termination style, and flange characteristics. Ensure compatibility with target PCB thickness and panel cutout dimensions prior to procurement. Confirm RoHS3 compliance status if required by project specifications. Cross-reference the DigiKey part number alias for accurate inventory tracking during sourcing.

Selection Notes

Select this connector when a dual-edge interface with a 0.156-inch pitch is required for vertical panel mounting. The single centerline row simplifies routing compared to double-row alternatives while maintaining high contact density. Verify that the target application environment falls within the specified operating temperature range. Consider the low-profile body height if space constraints are critical for the enclosure design.
