ACC28DRSH

Edgeboard Connectors Overview

The ACC28DRSH is a dual-row female card edge connector manufactured by Sullins Connector Solutions. It features 56 total contacts arranged in two rows of 28 positions, with a 0.100-inch (2.54mm) pitch. The connector utilizes phosphor bronze contacts with a gold plating finish and bellowed contact types for reliable engagement. Designed for through-hole mounting, it accommodates board thicknesses of 0.062 inches (1.57mm). The insulator is constructed from polyphenylene sulfide (PPS), providing durability across an operating temperature range of -65°C to 150°C.

Edgeboard Connectors Feature Summary

• Dual-row female configuration with 56 total positions for high-density interconnect applications
• Gold-plated phosphor bronze bellowed contacts ensure stable electrical performance
• Polyphenylene sulfide (PPS) insulation offers thermal stability and mechanical strength
• Through-hole termination supports secure PCB attachment with top-mount flange openings

Edgeboard Connectors Applications

• Industrial control systems requiring robust signal transmission
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement devices needing reliable high-cycle connectivity
• Automotive electronics modules operating within extended temperature ranges

Edgeboard Connectors Procurement Notes

Verify the specific suffix code (e.g., -S288, -S328) against official Sullins documentation to confirm exact plating thickness, lead-free status, and packaging details. Ensure compatibility with target board thickness and mounting hole specifications before ordering. Cross-reference RoHS compliance requirements with the latest manufacturer datasheet to meet regulatory standards for your specific application region.

Edgeboard Connectors Selection Notes

Select this model when a 0.100-inch pitch dual-row female connector is required for general-purpose card edge applications. Consider the PPS material for environments demanding higher thermal resistance compared to standard nylon variants. Verify that the unthreaded top-mount flange design aligns with the mechanical constraints of the enclosure. Confirm that the contact material and plating thickness meet the signal integrity and cycle life requirements of the system.

Edgeboard Connectors Part Context

This component belongs to the ACC series of card edge connectors from Sullins Connector Solutions, designed for versatile industrial and commercial use. The ACC series typically features through-hole termination and standardized dimensions for easy integration into existing designs. Variants within this family often differ by contact count, pitch, and insulator material, allowing engineers to tailor solutions for specific density and environmental needs without changing the fundamental form factor.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include other Sullins models with identical 0.100-inch pitch and 56-position dual-row configurations, such as the RSC28DRAN or ACM28DRAN, provided they match the specific termination style and flange requirements. Always verify pinout compatibility and mechanical fit before substituting.
