B5743-206-M-T-A

Overview

The Harwin B5743-206-M-T-A is a vertical header connector from the Datamate L-Tek series. It features 6 positions with a 2.00mm (0.079 inch) mating pitch and 2 rows. Designed for through-hole termination, it utilizes male pin contacts with gold plating on phosphor bronze. The housing is black, flame-retardant polyester reinforced with glass fiber. Rated for 800V and 2.2A, it operates within a temperature range of -55°C to +125°C. The connector includes a four-wall shroud and employs a pin-lock fastening mechanism.

Feature Summary

• Vertical board-to-board or cable connection design
• Pin-lock fastening mechanism for secure engagement
• Four-wall shrouded configuration for alignment
• Gold-plated phosphor bronze contacts

Applications

• Compact electronic assemblies requiring vertical interconnects
• Board-to-board connections in space-constrained environments
• Cable-to-board interfaces in industrial equipment

Procurement Notes

Verify component authenticity against official Harwin documentation due to potential counterfeit risks. Confirm that the specific suffix matches the required contact type and termination style. Check current availability status as this part may be subject to discontinuation notices. Ensure compatibility with mating sockets regarding locking mechanisms and shroud dimensions before procurement.

Selection Notes

Select this component when a vertical orientation is required for a 6-position interface. Verify that the 2.00mm pitch aligns with the PCB layout constraints. Ensure the operating environment stays within the specified -55°C to +125°C range. Confirm that the 800V rating meets the circuit requirements. Consider the pin-lock feature if vibration resistance is necessary for the application.
