RBA22DRMI-S288

Edgeboard Connectors Overview

The RBA22DRMI-S288 is a dual-row female card edge connector manufactured by Sullins Connector Solutions. It features 44 total positions arranged in two rows of 22 contacts each, with a 0.125-inch (3.18mm) pitch. The connector utilizes phosphor bronze contacts with a gold plating thickness of 30.0µin (0.76µm). Designed for board edge mounting via wire wrap termination, it accommodates a card thickness of 0.062 inches (1.57mm). The housing is constructed from polybutylene terephthalate (PBT), supporting an operating temperature range of -65°C to 125°C.

Edgeboard Connectors Feature Summary

• Dual-row configuration with 22 contacts per row for high-density interconnection
• Wire wrap termination method ensures secure electrical connection to the PCB
• Gold-plated phosphor bronze contacts provide reliable conductivity and corrosion resistance
• Polybutylene terephthalate insulation offers thermal stability within specified operating ranges

Edgeboard Connectors Applications

• Edgeboard connectors for modular electronic systems
• Industrial control panel interconnections
• Telecommunications equipment backplanes
• Test and measurement instrument interfaces

Edgeboard Connectors Procurement Notes

Verify the specific suffix S288 against official Sullins Connector Solutions documentation to confirm packaging and environmental compliance details. Ensure the required contact plating thickness and material composition match the application's performance requirements. Cross-reference the pin count and pitch specifications with the target card edge design to guarantee mechanical compatibility.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 0.125-inch pitch connector with wire wrap termination is required. Consider the PBT insulation material and -65°C to 125°C temperature rating for environmental suitability. Verify that the 0.062-inch card thickness constraint aligns with the system's PCB design. Confirm RoHS compliance status through manufacturer datasheets before integration.

Edgeboard Connectors Part Context

This part belongs to the RBA series of card edge connectors from Sullins Connector Solutions. The series typically includes various configurations differing in row count, pitch, and termination style. The RBA22 variant specifically denotes a 22-contact-per-row layout. The DRM suffix indicates dual-row female contacts, while MI specifies the mounting and termination characteristics unique to this model.

Edgeboard Connectors Replacement Considerations

Direct substitutes must maintain identical 0.125-inch pitch, 44-position count, and wire wrap termination. Verify mechanical dimensions and flange features for compatibility. Alternative parts from other manufacturers require careful evaluation of contact material and plating specifications to ensure equivalent performance.
