ABC70DKNS-S1243

Edgeboard Connectors Overview

The ABC70DKNS-S1243 is a dual-edge female card edge connector manufactured by Sullins Connector Solutions. It features 140 total positions arranged in two rows of 70 pins each, with a 0.100 inch (2.54mm) pitch. The contacts are made of beryllium copper with a gold plating thickness of 10.0 microinches (0.25 micrometers). Designed for through-hole, right-angle mounting, it accommodates a card thickness of 0.062 inches (1.57mm). The insulator is constructed from polyphenylene sulfide (PPS), supporting an operating temperature range of -65°C to 150°C.

Edgeboard Connectors Procurement Notes

Verify the specific suffix S1243 against official Sullins documentation to confirm flange and termination details. Ensure compatibility with 0.062-inch card thickness. Confirm RoHS compliance status if required for your assembly process. Cross-reference the full part number to avoid confusion with similar ABC series variants that may differ in contact material or plating specifications.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with 140 positions is required. The 0.100-inch pitch suits standard industrial board layouts. Consider the right-angle through-hole mounting style for space-constrained PCB designs. Verify that the 4-40 threaded insert flange matches your chassis or panel mounting requirements before finalizing the design.

Edgeboard Connectors Part Context

This connector belongs to the ABC series of card edge connectors from Sullins Connector Solutions. The series offers various configurations for single and dual-edge applications. The ABC70DKNS-S1243 specifically addresses needs for high-pin-count, dual-sided connections. It is part of a broader lineup designed for reliability in demanding electronic environments.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same family include ABC70DKNN-S1243 and ABC70DKRI-S1243. These parts share the 140-position dual-edge female form factor. Verify that any replacement maintains the same 0.062-inch card thickness tolerance and 4-40 flange mounting interface to ensure mechanical compatibility.
