123A-40M00

Edgeboard Connectors Overview

The 123A-40M00 is a 67-position female M.2 (NGFF) edgeboard connector designed for horizontal surface mount technology (SMT). It features an M Key configuration with a 0.5 mm pitch and gold flash contact finish. The component supports PCIe 3.0, SATA, and USB interfaces, operating within a temperature range of -40°C to 85°C. Constructed with liquid crystal polymer insulation, it offers a compact height of 4.0 mm.

Edgeboard Connectors Feature Summary

• Supports high-speed data transmission via PCIe 3.0, SATA, and USB interfaces
• Utilizes gold flash plating for stable conductivity in a compact design
• Engineered with liquid crystal polymer insulation for thermal stability

Edgeboard Connectors Applications

• Data storage modules requiring M.2 connectivity
• Wireless network interface cards
• Compact computing devices utilizing NGFF form factors

Edgeboard Connectors Procurement Notes

Verify the specific datasheet version when ordering, as documentation may reference H2.1 A Key specifications despite the commercial listing indicating M Key. Confirm that the gold flash finish meets the required conductivity standards for the intended application. Ensure the horizontal SMT mounting style aligns with the PCB layout constraints.

Edgeboard Connectors Selection Notes

Select this model for applications requiring a low-profile 4.0 mm height connector with M Key compatibility. It is suitable for designs needing support for multiple high-speed protocols including PCIe and SATA. Verify that the 67-pin count matches the target card's pinout requirements.

Edgeboard Connectors Part Context

This component belongs to the ATTEND 123A Series of M.2 connectors, which are engineered for advanced data transmission and wireless applications. The series includes variants with different keying options such as A/B/E/M Keys and varying heights. This specific part represents the M Key variant optimized for standard NGFF mini cards.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other 123A series models with identical 67-position M Key configurations and 4.0 mm height, such as 123A-40B00 if B Key compatibility is acceptable. Cross-model replacement requires verifying pinout compatibility and mechanical footprint alignment.
