Overview
The B5743-234-M-T-R is a male pin header from the Harwin Datamate L-Tek series, designed for board-to-board or cable connections. It features a 34-position configuration with two rows and a 2.00mm pitch. The connector utilizes vertical through-hole solder termination and includes four-wall shrouding for secure alignment. Rated for 800VAC/DC and 2.2A, it operates within a temperature range of -55°C to 125°C. The housing is constructed from UL94 V-0 rated polyester reinforced with glass fiber.
Feature Summary
- Four-wall shrouded design ensures precise mating alignment and protection
- Secure pin-locking mechanism prevents accidental disconnection during operation
- High-temperature resistant housing material supports demanding thermal environments
Applications
- Industrial control systems requiring robust interconnects
- Medical equipment needing reliable signal transmission
- Automotive electronics subject to vibration and thermal stress
Procurement Notes
Verify the specific suffix 'R' against official Harwin documentation to confirm reel packaging specifications. Ensure compatibility with mating sockets in the same Datamate L-Tek family. Confirm that the lead-free status aligns with project requirements, as standard variants may contain tin-lead plating on posts.
Selection Notes
Select this component when a high-density, latched connection is required for vertical mounting. The 2.00mm pitch allows for compact circuit layouts while maintaining adequate spacing. Consider the four-wall shroud for applications where misalignment risks exist. Verify current ratings against load requirements to ensure safe operation under maximum conditions.
Part Context
This part belongs to the Datamate L-Tek family, known for its modular design and high reliability. The series offers various configurations for different connection needs. The B5743 prefix indicates a male header variant. This specific model provides a balance of density and mechanical security for critical electronic assemblies.
Replacement Considerations
M80-8673422 is an alternative designation for this component. Cross-reference with other Harwin headers in the L-Tek series for similar form factors. Ensure mating parts share the same 2.00mm pitch and locking mechanism for functional interchangeability.
