B5743-234-M-L-2

Overview

The B5743-234-M-L-2 is a male pin header connector from the Harwin Datamate L-Tek series. It features a 34-position, dual-row configuration with a 2.00mm (0.079 inch) pitch. Designed for through-hole mounting, this right-angle connector utilizes a shrouded housing to ensure proper alignment during mating. The contacts are gold-plated phosphor bronze pins, providing reliable electrical performance in board-to-board or cable applications.

Feature Summary

• Right-angle through-hole mounting orientation for compact PCB integration
• Shrouded four-wall design ensures precise pin alignment and protection
• Gold-plated phosphor bronze contacts for durable signal transmission

Applications

• Board-to-board interconnections requiring right-angle routing
• Cable assemblies connecting to rigid printed circuit boards
• Industrial control systems utilizing high-density I/O interfaces

Procurement Notes

Verify the specific suffix 'L-2' confirms the right-angle orientation and two-row configuration, as Harwin naming conventions are strict. Ensure compatibility with mating sockets from the same Datamate L-Tek family. Confirm that the target PCB layout accommodates the right-angle profile and sufficient clearance for the shrouded housing height.

Selection Notes

Select this model when space constraints require a perpendicular connection between the connector and the PCB plane. The 34-position count suits high-density data or power distribution needs. Compare against vertical variants if straight mounting is preferred, and ensure the mating partner supports the 2.00mm pitch and latch mechanism.

Part Context

This component belongs to the Datamate L-Tek family, known for robust mechanical locking and high cycle life. The B5743 prefix typically denotes male headers within this ecosystem. The L-Tek series is widely used in demanding environments due to its secure pin-locking feature and resistance to vibration.

Replacement Considerations

Direct substitutes include other 34-position, 2.00mm pitch, right-angle male headers from Harwin's Datamate range. Verify that any alternative maintains the same shrouded design and contact plating specifications to ensure mechanical and electrical compatibility.
