ACM25DCKH-S288

Edgeboard Connectors Overview

The ACM25DCKH-S288 is a dual-edge female card edge connector manufactured by Sullins Connector Solutions. It features 50 positions arranged in two rows of 25 contacts, utilizing a 0.156-inch (3.96mm) center-to-center spacing. The connector employs gold-plated phosphor bronze contacts with a ring spring termination style for reliable signal transmission. Designed for board edge mounting, it accommodates a card thickness of 0.062 inches and operates within a temperature range of -65°C to 125°C.

Edgeboard Connectors Procurement Notes

Verify the specific suffix requirements against your design specifications to ensure compatibility with mating cards. Confirm that the 0.156-inch pitch aligns with your PCB layout constraints. Check RoHS compliance status if required by your assembly standards. Ensure the operating temperature range meets your environmental conditions. Cross-reference the flange dimensions with your chassis mounting holes.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 0.156-inch pitch is required. Consider the ring spring contact type for applications demanding high cycle life and vibration resistance. Evaluate the phosphor bronze material for its electrical conductivity and mechanical strength. Verify that the 50-position count matches your circuit density needs. Assess the thermal rating for your specific operational environment.

Edgeboard Connectors Part Context

This part belongs to the Sullins Connector Solutions edgeboard connector family, designed for robust interconnect solutions. It shares common mounting characteristics with other models in the series but differs in pitch and position count. The dual-edge design allows for increased I/O density compared to single-edge variants. It is intended for use in environments requiring reliable electrical connections over extended periods.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include other Sullins models with identical 0.156-inch pitch and 50-position dual-edge configurations. Verify that any replacement maintains the same ring spring contact style and gold plating thickness. Ensure the flange dimensions and mounting hole patterns are compatible with existing hardware. Check for equivalent thermal and electrical ratings before substitution.
