Overview
The Harwin B5743-212-M-T-B is a Datamate L-Tek series header connector designed for board-to-board or cable applications. It features a vertical through-hole mounting style with 12 positions arranged in a double row configuration. The mating pitch is 0.079 inches (2.00mm). The contacts are male pins with gold plating on the mating area and tin/lead finish on the termination side. The insulator is black, glass-filled polyester rated UL94 V-0. Rated current is 2.2A at 800V AC/DC. Operating temperature range is -55°C to +125°C.
Feature Summary
- Four-wall shrouded design ensures precise alignment during mating
- Pin lock mechanism provides secure retention of the mating plug
- Gold-plated contact surfaces ensure reliable signal transmission
- Vertical orientation supports compact PCB layout requirements
Applications
- Industrial control systems requiring robust interconnects
- Automotive electronics modules
- Telecommunications equipment backplanes
- Medical device internal connections
Procurement Notes
Verify the specific suffix 'B' indicates the correct termination finish and packaging type compared to variant '1'. Confirm RoHS compliance status as some variants may differ. Check lead times for tube packaging quantities. Ensure the pin count matches the 12-position requirement for the target circuit design before ordering.
Selection Notes
Select this model when a vertical, shrouded header with pin-locking capability is required. The 2mm pitch suits high-density applications. Consider the 800V rating for higher voltage circuits. Compare against non-shrouded alternatives if space constraints allow. Verify PCB hole dimensions match the through-pin specifications.
Part Context
This component belongs to the Datamate L-Tek family, known for high-reliability interconnect solutions. The B5743 prefix denotes a male header variant. The 'M' indicates male pins, 'T' signifies through-hole termination, and 'B' specifies the particular insulation and contact finish combination within the product line.
Replacement Considerations
Direct substitutes include other Harwin Datamate headers with identical 2mm pitch and 12-position count. Cross-reference part numbers like M80-8671222 for equivalent specifications. Ensure mechanical stacking heights and locking mechanisms are compatible with existing assembly processes.
