ECC44DKND

Edgeboard Connectors Overview

The ECC44DKND is a dual-edge female card edge connector manufactured by Sullins Connector Solutions. It features 88 positions arranged in two rows of 44 contacts each, with a 0.100 inch (2.54mm) pitch. The connector supports a maximum card thickness of 0.062 inches (1.57mm). Contact materials consist of phosphor bronze with a gold plating finish of 30.0 microinches (0.76 micrometers). The insulating material is polybutylene terephthalate (PBT), and the unit operates within a temperature range of -65°C to 125°C. It utilizes cantilever contact types for reliable engagement.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration designed for non-specified card applications
• Cantilever contact type ensures secure connection to board edges
• Gold-plated phosphor bronze contacts provide corrosion resistance
• Flush mount design with top opening and unthreaded flange

Edgeboard Connectors Applications

• Industrial control systems requiring robust edge connections
• Telecommunications equipment interface modules
• Computer peripheral expansion boards
• Test and measurement instrumentation backplanes

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against official Sullins documentation to confirm mechanical variations such as flange style or mounting orientation. Ensure compatibility with target PCB stack-up and card thickness specifications before ordering. Confirm RoHS compliance status matches project requirements. Cross-reference lead times with authorized distributors as availability may vary by region.

Edgeboard Connectors Selection Notes

Select this model when a dual-edge female connector with cantilever contacts is required for standard 0.100 inch pitch applications. Consider the flush mount installation type and PBT insulation material for environmental stability. Evaluate thermal operating limits against system constraints. Compare alternative series like ECC44DREN if free-hanging mounting is preferred over flush configurations.

Edgeboard Connectors Part Context

This component belongs to the ECC44 series of card edge connectors from Sullins Connector Solutions. The series offers various mounting options and contact configurations tailored for high-reliability interconnects. The ECC44DKND specifically addresses needs for flush-mounted dual-edge solutions with standardized dimensions compatible with industry-standard card profiles.

Edgeboard Connectors Replacement Considerations

ECC44DCSD-S288: Offers similar electrical specs but uses a cantilever mount style instead of flush. ECC44DTKS: Provides through-hole mounting with side-opening flanges rather than flush top-opening. Verify mechanical fit and flange characteristics when substituting.
