FMM22DSEH-S243

Edgeboard Connectors Overview

The FMM22DSEH-S243 is a dual-edge female card edge connector manufactured by Sullins Connector Solutions. It features 44 contacts arranged in two rows with a 0.156-inch pitch. The component utilizes full bellows contact types made from beryllium copper, finished with 10µin gold plating over nickel. Designed for panel mounting, it accommodates a card thickness of 0.062 inches and operates within a temperature range of -65°C to 125°C.

Edgeboard Connectors Feature Summary

• Full bellows contact design ensures reliable mating force and low contact resistance
• Locking mechanism provides secure retention during operation
• Gold-plated beryllium copper contacts offer corrosion resistance
• Panel mount configuration supports stable structural integration

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules
• Embedded computing board connections

Edgeboard Connectors Procurement Notes

Verify the specific suffix S243 against the official manufacturer datasheet to confirm exact plating thickness and material specifications. Ensure compatibility with the target PCB panel thickness of 0.062 inches. Confirm RoHS compliance status and ECCN classification EAR99 for export requirements before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this connector when high reliability and secure locking are required for dual-edge card applications. The 0.156-inch pitch suits standard industrial board layouts. Consider the 125°C operating limit for thermal environments. Verify that the panel mount hole dimensions align with the specified .120-.126 inch options for proper mechanical fit.

Edgeboard Connectors Part Context

This component belongs to the ESM series family of card edge connectors from Sullins Connector Solutions. It shares the standard 0.156-inch pitch architecture common to this product line. The part number indicates a dual-edge female configuration with specific locking and mounting characteristics defined by the suffix codes.

Edgeboard Connectors Replacement Considerations

Cross-reference with FSM22DSEH-S243 or FMM22DSES for similar electrical characteristics. Verify mechanical dimensions and pinout compatibility before substitution. Ensure the alternative part meets the same 0.062-inch card thickness requirement and panel mounting constraints.
