ASC28DREN-S734

Edgeboard Connectors Overview

The ASC28DREN-S734 is a dual-edge female card edge connector manufactured by Sullins Connector Solutions. It features 56 positions arranged in two rows of 28 contacts each, with a 0.100 inch (2.54 mm) spacing. The connector utilizes phosphor bronze contacts with a gold plating thickness of 30.0 µin (0.76 µm). Designed for free-hanging installation and through-hole termination, it accommodates a board thickness of 0.031 inches (0.79 mm). The housing is made of polyphenylene sulfide (PPS), rated for operation between -65°C and 125°C, and complies with RoHS3 standards.

Edgeboard Connectors Feature Summary

• Dual-edge configuration with full bellows contact type for reliable signal transmission
• Gold-plated phosphor bronze contacts ensure corrosion resistance and low contact resistance
• Polyphenylene sulfide insulation provides high thermal stability and mechanical strength

Edgeboard Connectors Applications

• Industrial control systems requiring robust edge-mounted interconnects
• Telecommunications equipment utilizing standard 0.100 inch pitch modules
• Test and measurement instrumentation boards

Edgeboard Connectors Procurement Notes

Verify the specific suffix S734 to confirm the 0.031-inch card thickness compatibility, as other suffixes may indicate different board thicknesses or material variations. Ensure the application environment remains within the specified -65°C to 125°C operating range. Confirm that the required gold plating thickness meets the design's conductivity and wear requirements before finalizing procurement specifications.

Edgeboard Connectors Selection Notes

Select this component when a dual-sided connection is required for a 0.031-inch thick PCB with 0.100-inch spacing. The PPS housing and gold-plated phosphor bronze contacts offer durability for repeated insertion cycles. Consider the free-hanging mounting style if panel mounting is not feasible. Compare against similar models like HSC28DREN only if board thickness or contact material differences are acceptable for the specific circuit design.

Edgeboard Connectors Part Context

This part belongs to the ASC series of card edge connectors from Sullins Connector Solutions, designed for high-reliability applications. The series typically offers various pin counts and board thickness options. The ASC28 variant specifically addresses mid-density connectivity needs, balancing contact count with compact footprint. It complements the broader portfolio of edge connectors used in modular electronic systems.
