RCM25DTKN-S288

Edgeboard Connectors Overview

The RCM25DTKN-S288 is a dual-edge female connector manufactured by Sullins Connector Solutions. It features 50 positions arranged in two rows of 25 contacts each, with a 0.156-inch (3.96mm) spacing. The connector utilizes phosphor bronze contacts with a gold surface finish and ring bellows contact types. Designed for board edge or straddle mount installation, it accommodates a card thickness of 0.062 inches (1.57mm). The insulating material is polyphenylene sulfide (PPS), supporting an operating temperature range of -65°C to 125°C.

Edgeboard Connectors Feature Summary

• Dual-row configuration providing 50 total connection points across two parallel edges.
• Straddle mount design allows secure attachment directly to the board edge.
• Gold-plated phosphor bronze contacts ensure reliable signal transmission.
• Polyphenylene sulfide insulation offers thermal stability within specified ranges.

Edgeboard Connectors Applications

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

Edgeboard Connectors Procurement Notes

Verify that the specific suffix matches the required mounting style and contact type. Confirm compatibility with the target PCB edge card thickness and slot dimensions. Ensure the gold plating specification meets the application's conductivity requirements. Check RoHS compliance status if environmental regulations apply to the final assembly.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with 0.156-inch spacing is required. The straddle mount option provides mechanical stability without additional fasteners. Consider the PPS material for high-temperature environments. Verify that the 50-position count aligns with the circuit density needs of the design.

Edgeboard Connectors Part Context

This part belongs to the RCM series of edge connectors from Sullins Connector Solutions. The series offers various pin counts and spacings to accommodate different board sizes. The RCM25 variant specifically targets applications needing moderate density connections on dual edges.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other Sullins models with identical 0.156-inch spacing and 50-position dual-edge configurations. Verify mechanical fit and electrical specifications before swapping manufacturers.
