Overview
The Harwin B5743-117-M-L-1 is a Datamate L-Tek male plug connector featuring 17 positions in a single row. It utilizes a 2.00mm pitch and is designed for right-angle through-board mounting with 3mm PCB termination length. The contacts are gold-plated phosphor bronze, while the housing is black polyester reinforced with glass fiber. Rated for 800VAC/DC and 2.2A, it operates within a -55°C to +125°C range and meets UL94 V-0 flammability standards.
Feature Summary
- Single-row male configuration with pin lock retention mechanism
- Right-angle orientation for horizontal board integration
- Gold-plated contact surfaces for reliable signal transmission
- Four-wall shrouded design for precise alignment
Applications
- Industrial control panel interconnections
- Embedded system board-to-board connections
- Test and measurement equipment interfaces
- Automotive electronics harnesses
Procurement Notes
Verify the specific suffix 'L' indicates the right-angle variant distinct from vertical headers. Confirm RoHS compliance status as some legacy listings may vary. Ensure the 3mm termination length matches the target PCB thickness requirements. Cross-reference the official Harwin datasheet for any recent engineering changes or obsolescence notices prior to finalizing procurement orders.
Selection Notes
Select this component when a single-row male connection is required at a right angle. The 2.00mm pitch accommodates standard density layouts. Verify that the 2.2A current rating suffices for the application load. Consider the 3mm termination height against available board space constraints compared to standard vertical alternatives.
Part Context
This part belongs to the Datamate L-Tek series, known for high-density interconnects. The B5743 prefix denotes a male plug header. The 'M' signifies male contacts, and 'L' specifies the right-angle form factor. It pairs with female sockets from the same family to create secure mating assemblies.
Replacement Considerations
Direct substitutes include B5743-117-M-T-1 for vertical mounting. For different row counts, check B5743-1xx variants. Ensure replacement parts maintain the 2.00mm pitch and right-angle geometry to preserve mechanical fit.
