Overview
The B5743-102-M-T-1 is a Datamate L-Tek male header connector manufactured by Harwin Inc. It features a 2-position configuration with a 2 mm (0.079 in) pitch. The component utilizes a right-angle, shrouded design intended for board-to-board or cable applications. Electrical specifications include a current rating of 2.2 A and a voltage rating of 120 VAC/DC. The contacts are gold-plated with a post finish thickness of 12.0 µin (0.30 µm). Installation is achieved via solder pin termination through-hole mounting.
Feature Summary
- Right-angle shrouded housing design for secure board-to-board alignment
- Integrated latch mechanism for positive mating retention
- Gold-plated phosphor bronze contacts ensuring reliable conductivity
- Through-hole solder pin termination for robust PCB attachment
Applications
- Compact electronic device interconnects
- Board-to-board signal transmission
- Industrial control module connections
- Consumer electronics internal wiring
Procurement Notes
Verify the specific suffix 'T' confirms the right-angle orientation and latch feature against the official Harwin datasheet. Confirm RoHS compliance status and REACH SVHC declarations prior to integration. Ensure the 2.2A current rating aligns with the target circuit requirements. Cross-reference the M80 catalog for complete mechanical drawings and mating partner compatibility.
Selection Notes
Select this model for applications requiring a low-profile, right-angle connection with positive latching. The 2 mm pitch suits dense board layouts. Compare against straight variants if space constraints differ. Validate that the 120VAC/DC rating meets system voltage needs. Consider the 2.2A current capacity for power distribution lines within the assembly.
Part Context
This component belongs to the Datamate L-Tek series, designed for high-density interconnect solutions. The B5743 prefix indicates a male header variant. The series is known for its compact form factor and reliable locking mechanisms. It serves as a standard interconnect solution within Harwin's rectangular connector portfolio, often paired with corresponding female housings.
Replacement Considerations
M80-8670222 is a documented equivalent part number for this component. Verify mechanical dimensions and contact plating specifications when substituting. Ensure the replacement maintains the right-angle orientation and latch functionality required for the assembly.
