GCM44DSEH-S243

Edgeboard Connectors Overview

The GCM44DSEH-S243 is an 88-position female card edge connector manufactured by Sullins Connector Solutions. It features a dual-edge design with two rows of contacts and a 0.156-inch (3.96mm) pitch. The connector utilizes phosphor bronze bellowed-type contacts with gold over nickel plating, achieving a contact resistance thickness of 30.0µin (0.76µm). Designed for panel mounting via top-mount openings with an unthreaded 0.125-inch diameter, it accommodates a card thickness of 0.062 inches. The insulator is constructed from polyamide (PA9T), supporting a temperature range of -65°C to 125°C.

Edgeboard Connectors Feature Summary

• Dual-edge configuration with 88 positions for high-density signal routing
• Full bellows contact style ensures reliable mating force and retention
• Gold over nickel plating provides corrosion resistance and stable conductivity
• Top-mount flange design facilitates secure panel installation

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• High-reliability computing modules
• Test and measurement instrumentation boards

Edgeboard Connectors Procurement Notes

Verify the specific suffix S243 against the manufacturer's current datasheet to confirm plating thickness and material specifications. Ensure compatibility with the target PCB edge card thickness of 0.062 inches. Confirm that the top-mount opening dimensions align with the mechanical constraints of the enclosure panel. Check RoHS compliance status if required by project regulations.

Edgeboard Connectors Selection Notes

Select this model when a dual-edge connection with a 0.156-inch pitch is required. The bellowed contact type offers superior retention compared to straight contacts. Consider the PA9T insulator material for its thermal stability within the specified operating range. Ensure the application does not require locking mechanisms or side-mounting options which are available in other variants.

Edgeboard Connectors Part Context

This component belongs to the GCM44 series of card edge connectors from Sullins Connector Solutions. The series is characterized by robust construction suitable for commercial and industrial environments. Variants within the series differ primarily in mounting orientation, contact termination style, and insulator material. The GCM44DSEH-S243 specifically denotes the dual-edge, eyelet termination version with standard gold plating.

Edgeboard Connectors Replacement Considerations

Direct substitutes include models sharing the same 88-position count, 0.156-inch pitch, and dual-edge configuration. Verify that any replacement maintains the same contact plating and insulator material properties. Cross-reference mounting hole dimensions to ensure mechanical fit without modification.
