EMM24DRXN

Edgeboard Connectors Overview

The EMM24DRXN is a dual-edge female card edge connector manufactured by Sullins Connector Solutions. It features 48 positions arranged in two rows of 24, with a pitch of 0.156 inches (3.96 mm). Designed for through-hole solder termination, the connector accommodates PC boards with a thickness of 0.062 inches (1.57 mm). The contacts are constructed from phosphor bronze and finished with 30 microinches (0.76 micrometers) of gold plating. The insulator material is polybutylene terephthalate (PBT), and the unit is colored blue. It operates within a temperature range of -65°C to 125°C.

Edgeboard Connectors Feature Summary

• Dual-edge female design for non-specified board types
• Full bellows contact type for reliable engagement
• Gold-plated phosphor bronze contacts for corrosion resistance
• Through-hole solder termination for secure mounting

Edgeboard Connectors Applications

• Industrial control systems requiring robust edge connections
• Telecommunications equipment interface modules
• Test and measurement instrumentation backplanes
• General-purpose electronic circuit board interconnects

Edgeboard Connectors Procurement Notes

Verify the specific suffix 'XN' against official Sullins documentation to confirm the exact termination style and packaging configuration. Ensure compatibility with the target PCB thickness of 0.062 inches. Confirm that the 0.156-inch pitch aligns with the design layout. Check RoHS compliance status if required by project specifications.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 0.156-inch pitch is required. The phosphor bronze contacts offer good mechanical stability. The PBT insulator provides necessary thermal resistance up to 125°C. Consider the blue color coding for visual identification during assembly. Verify that the through-hole mounting method fits the manufacturing process.

Edgeboard Connectors Part Context

This part belongs to the EMM24 series of female card edge connectors from Sullins Connector Solutions. The series offers various configurations differing in contact material, insulation type, and flange options. The EMM24DRXN specifically utilizes phosphor bronze contacts and PBT insulation, distinguishing it from variants using beryllium copper or different polymer materials.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other Sullins models within the EMM24 family, such as EMM24DSUN or EMM24DRTN, provided they match the required contact material and insulation properties. Cross-manufacturer replacements must strictly adhere to the 0.156-inch pitch, 48-position count, and dual-edge form factor.
