B5743-234-M-T-0

Overview

The B5743-234-M-T-0 is a male pin header connector from the Harwin Datamate L-Tek series. It features a vertical through-hole mounting style with 34 positions arranged in a dual-row configuration. The connector utilizes a 2.00mm (0.079 inch) mating pitch and includes a four-wall shroud for alignment and protection. Contact materials consist of phosphor bronze, with gold plating on the mating interface and tin-lead plating on the posts. Rated for 800VAC/DC and 2.2A, it operates within a temperature range of -55°C to 125°C.

Feature Summary

• Dual-row male pin design with four-wall shrouding
• Vertical through-hole termination for board mounting
• Gold-plated mating contacts for reliable signal transmission
• High voltage rating suitable for industrial applications

Applications

• Industrial control system interconnections
• Test and measurement equipment interfaces
• Data acquisition module connections
• Automotive electronic subsystem linking

Procurement Notes

Verify the specific suffix 'T-0' against official Harwin documentation to confirm exact plating specifications and compliance status. Ensure that the tin-lead post plating aligns with project environmental requirements. Cross-reference the datasheet for precise mechanical dimensions and mating partner compatibility before finalizing procurement orders.

Selection Notes

Select this component when a high-density, vertically mounted male header is required for robust electrical connections. The 2.00mm pitch allows for compact circuit board layouts while maintaining adequate spacing. Consider the shrouded design for improved mating accuracy and the high voltage rating for safety-critical circuits requiring isolation.

Part Context

This part belongs to the Datamate L-Tek family, known for its versatility in board-to-board and cable-to-board applications. The series offers various row counts and termination options. The B5743 variant specifically denotes a male header with through-hole soldering, providing a secure mechanical bond to the printed circuit board.

Replacement Considerations

Compatible mating sockets include the B5740 series female headers with matching 2.00mm pitch. Verify latch mechanisms if quick release functionality is required. Ensure replacement parts maintain identical current ratings and temperature tolerances for system integrity.
