AMM22DTBD-S273

Edgeboard Connectors Overview

The AMM22DTBD-S273 is a dual-edge female card edge connector manufactured by Sullins Connector Solutions. It features 44 positions arranged in two rows, with a contact pitch of 0.156 inches (3.96 mm). Designed for through-hole right-angle mounting, the connector accommodates non-specified dual-edge cards with a thickness of 0.093 inches (2.36 mm). The contacts are constructed from phosphor bronze and feature a gold finish with a thickness of 10.0 µin (0.25 µm). The insulator material is polyamide.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration with loop bellows contact type for secure mating
• Through-hole right-angle termination suitable for standard PCB assembly
• Gold-plated phosphor bronze contacts ensuring reliable signal transmission
• Flange features include flush mount, top opening, and threaded inserts

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
• General-purpose electronic assemblies needing high-density interconnects

Edgeboard Connectors Procurement Notes

Verify that the mating printed circuit board utilizes a double-sided edge design compatible with the specified 0.093-inch thickness. Confirm that the application environment remains within the operational temperature range and that the required current rating does not exceed the component specifications. Ensure proper handling procedures are followed to protect the gold-plated contacts from contamination during storage and installation.

Edgeboard Connectors Selection Notes

Select this model when a right-angle, through-hole connection is required for non-specified dual-edge cards. The 0.156-inch pitch provides a balance between density and mechanical stability. Consider the flange mounting options if panel or chassis attachment is necessary. Verify insulation material compatibility with soldering processes and environmental conditions specific to the target application.

Edgeboard Connectors Part Context

This component belongs to the Sullins Connector Solutions card edge connector family, designed for high-reliability interconnect applications. The series offers various configurations to accommodate different card types and mounting requirements. The AMM22DTBD-S273 specifically addresses needs for dual-edge connections with standardized dimensions and durable contact materials.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include ECM22DTBT-S273 and GMM22DTMD-S273, which share similar electrical characteristics and form factors. Verify pin count, pitch, and termination style before substitution. Ensure that any alternative part meets the same mechanical and environmental standards required for the existing design.
