Overview
The Harwin B5743-212-M-T-U is a Datamate L-Tek series male pin header designed for through-hole board-to-board or cable connections. It features a 2 mm pitch, double-row configuration with 12 positions, and shrouded four-wall housing. The connector supports a current rating of 2.2A and a voltage rating of 120V. Mated stacking heights are specified at 7.23mm and 7.85mm. The unit utilizes UL94 V-0 rated black insulation and solder terminations.
Feature Summary
- Shrouded four-wall housing design provides mechanical protection and alignment for mating connectors.
- Integrated locking latches ensure secure connection stability during operation.
- Through-hole termination style offers robust mechanical attachment to printed circuit boards.
Applications
- Board-to-board interconnects in industrial control systems
- Cable assemblies requiring secure vertical mounting
- Compact electronic modules needing high-density I/O
Procurement Notes
Verify the specific suffix 'U' against the official Harwin datasheet to confirm material flammability and environmental compliance status. Ensure the selected variant matches the required stacking height specifications for the target assembly. Cross-reference the RoHS and REACH declarations with the latest manufacturer documentation prior to procurement.
Selection Notes
Select this component when a shrouded, latched male header is required for vertical through-hole mounting. The 12-position, 2-row layout suits applications needing moderate density within a small footprint. Confirm that the 2.2A current rating and 120V voltage limits align with the system's electrical requirements and operating conditions.
Part Context
This part belongs to the Datamate L-Tek family, known for compact, high-reliability interconnect solutions. The B5743 series specifically targets board-to-board and cable applications where space constraints and secure locking mechanisms are critical. It complements female counterparts within the same ecosystem to form complete connection systems.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Verify compatibility with mating female connectors from the same Datamate L-Tek series before considering alternative sourcing options.
