Edgeboard Connectors datasheet and documents for 123A-42B02
Edgeboard Connectors Overview
The ATTEND Technology 123A-42B02 is an M.2 Gen5 socket connector featuring a B Key configuration with a height of 4.2 mm and a 0.5 mm pitch. It contains 67 contacts and utilizes gold flash plating for conductivity. The component operates within a temperature range of -40°C to 85°C, with insulation constructed from liquid crystal polymer.
Edgeboard Connectors Feature Summary
- Supports PCIe, SATA 3.0, and USB 3.0 protocols via A/B/E/M key options in the series
- Utilizes gold flash contact finish to enhance electrical conductivity
- Constructed with liquid crystal polymer insulation material
Edgeboard Connectors Applications
- M.2 module interconnection on edgeboard systems
- High-speed data transfer interfaces requiring Gen5 support
- Portable computing devices utilizing B-key M.2 slots
Edgeboard Connectors Procurement Notes
Verify that the specific application requires a B-key configuration and a 4.2mm mounting height. Confirm compatibility with Gen5 signaling standards before procurement. Ensure the operating environment remains within the specified -40°C to 85°C range. Check for required latch accessories if mechanical retention is needed for the connected module.
Edgeboard Connectors Selection Notes
Select this component when a low-profile M.2 socket is required for B-key modules. The 4.2mm height suits space-constrained designs compared to taller variants. Consider the 67-contact count for necessary signal routing. Evaluate thermal requirements against the specified operating temperature limits.
Edgeboard Connectors Part Context
This part belongs to the ATTEND 123A series of M.2 connectors. The series supports various keying options including A, B, E, and M keys. Other models in the family offer different heights such as 2.1mm, 3.0mm, and 8.5mm to accommodate diverse board thicknesses and mechanical constraints.
Edgeboard Connectors Replacement Considerations
Direct substitutes include other 123A series sockets with identical B-key and 4.2mm height specifications, such as the 123A-42B02 variant from the same manufacturer line. Verify pin count and pitch match exactly.
