HMC26DREF-S13

Edgeboard Connectors Overview

The HMC26DREF-S13 is a dual-edge card edge connector manufactured by Sullins Connector Solutions. It features 52 positions arranged in two rows of 26, with a 0.100-inch (2.54mm) pitch. Designed for non-specified dual-edge cards, it supports a maximum card thickness of 0.062 inches (1.57mm). The connector utilizes beryllium copper contacts with a 30µin gold finish and employs solder eyelet termination. It is rated for operation between -65°C and 125°C.

Edgeboard Connectors Feature Summary

• Straddle mount board edge installation for secure mechanical attachment
• Card extended feature facilitates alignment during insertion
• Gold-plated beryllium copper contacts ensure reliable signal transmission
• Dual-row configuration provides high-density interconnect capability

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connections
• Telecommunications equipment utilizing standard dual-edge circuit boards
• Computing hardware modules needing secure peripheral interfaces
• Test and measurement instrumentation with high-reliability requirements

Edgeboard Connectors Procurement Notes

Verify the specific suffix designation to confirm contact material composition and insulation properties, as variations exist within the product family. Ensure the target application accommodates the specified 0.062-inch maximum card thickness. Confirm that the straddle mount style aligns with the PCB layout and panel mounting constraints. Cross-reference the RoHS compliance status if environmental regulations apply to the final assembly process.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge interface with a 0.100-inch pitch is required for non-specific card types. The beryllium copper contact material offers superior spring retention compared to alternative alloys. Consider the operating temperature range of -65°C to 125°C against environmental conditions. The solder eyelet termination method dictates the specific PCB fabrication requirements for wave or selective soldering processes.

Edgeboard Connectors Part Context

This part belongs to the HMC series of edgeboard connectors from Sullins Connector Solutions. The series is characterized by its use of beryllium copper contacts and PBT insulation. Variations in the suffix indicate differences in packaging or specific manufacturing batches. The base model HMC26 defines the fundamental electrical and mechanical specifications shared across the series.

Edgeboard Connectors Replacement Considerations

HMC26DREH serves as a comparable alternative within the same series, maintaining similar mechanical dimensions but potentially differing in contact material or insulation type. Verify compatibility with existing PCB footprints before substitution.
