ESM28DRSS

Edgeboard Connectors Overview

The ESM28DRSS is a dual-edge female card edge connector manufactured by Sullins Connector Solutions. It features 56 positions arranged in two rows of 28 contacts, with a pitch of 0.156 inches (3.96mm). The connector utilizes phosphor bronze contacts with a gold plating thickness of 30.0µin (0.76µm) and full bellows contact types. Designed for through-hole termination, it accommodates a board thickness of 0.062 inches (1.57mm). The insulator is made of polyphenylene sulfide (PPS), and the unit operates within a temperature range of -65°C to 125°C.

Edgeboard Connectors Feature Summary

• Dual-edge female interface design for secure printed circuit board connection
• Full bellows contact type ensures reliable signal transmission
• Gold-plated phosphor bronze contacts provide corrosion resistance
• Polyphenylene sulfide insulator supports high-temperature operation

Edgeboard Connectors Applications

• Edge-card interface connections in electronic assemblies
• Dual-sided PCB mounting applications
• Industrial control system interconnects
• Communication equipment backplane interfaces

Edgeboard Connectors Procurement Notes

Verify the specific suffix DRSS corresponds to the required gold plating thickness of 30.0µin and PPS insulator material. Confirm that the through-hole termination method matches the target PCB layout. Ensure the operating temperature range meets environmental requirements. Check RoHS3 compliance status if restricted substances are a concern. Validate the dual-edge configuration against mechanical constraints.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 0.156-inch pitch is required. The full bellows contact type offers superior retention force compared to standard wiper contacts. The PPS insulator provides better thermal stability than PBT alternatives. Verify that the 56-position count aligns with the circuit density needs. Ensure the through-hole mounting style is compatible with the assembly process.

Edgeboard Connectors Part Context

This part belongs to the ESM series of card edge connectors from Sullins Connector Solutions. The series includes various configurations differing by contact type, plating thickness, and insulator material. The ESM28DRSS specifically denotes the dual-row, 28-contact-per-side variant with defined electrical and mechanical specifications for industrial use.

Edgeboard Connectors Replacement Considerations

ESM28DRXS is a similar dual-edge connector but uses PBT insulator and 10.0µin gold plating. GSM28DRSS shares the same pitch and position count but differs in color and potentially packaging. GMM28DTKS features a different flange design and nylon 9T insulator. Verify mechanical fit and electrical specs before substitution.
