RCM22DCWI

Edgeboard Connectors Overview

The RCM22DCWI is a dual female card edge connector manufactured by Sullins Connector Solutions. It features 44 contacts arranged in two rows with a 0.156-inch pitch. The connector utilizes a straight, through-hole mounting style and solder termination. Contact surfaces are gold-plated to a thickness of 30.0µin over phosphor bronze bases. Designed for non-specified dual-edge cards with a maximum thickness of 0.062 inches, it includes flange features such as top-mount openings and 4-40 threaded inserts. The insulator is constructed from polyphenylene sulfide (PPS), supporting an operating temperature range of -65°C to 125°C.

Edgeboard Connectors Feature Summary

• Dual-row female configuration providing 44 total contact positions for high-density interconnection.
• Gold-plated phosphor bronze contacts ensure reliable signal transmission and corrosion resistance.
• Integrated flange design with top-mount openings and threaded inserts facilitates secure panel installation.

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connectivity
• Telecommunications equipment utilizing standard double-sided edge cards
• Test and measurement instrumentation interfaces

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the manufacturer's current catalog to confirm exact plating thickness and material specifications. Ensure compatibility with the target PCB layout regarding hole spacing and mechanical clearance. Confirm that the selected variant meets all necessary environmental certifications for the intended deployment region. Cross-reference the package type to align with automated assembly requirements.

Edgeboard Connectors Selection Notes

Select this model when a 0.156-inch pitch is required for dual-edge card applications. The straight through-hole design suits vertical board connections. Verify that the 0.062-inch card thickness limit accommodates the target circuit board. Consider the PPS insulation material for thermal stability within the specified operating range during system integration.
