Overview
The M80-8280422 is a Datamate L-Tek series header connector manufactured by Harwin Inc. It features a surface mount installation type with four positions arranged in a dual-row configuration. The mating pitch is 0.079 inches (2.00mm), and the row spacing is also 0.079 inches (2.00mm). The connector utilizes male pin contacts made of phosphor bronze with gold plating on the mating surfaces. The housing is constructed from black polyphenylene sulfide (PPS) reinforced with glass fiber, meeting UL94 V-0 flammability ratings. It supports board-to-board or cable applications.
Feature Summary
- Surface mount design for automated PCB assembly
- High-reliability Datamate L-Tek interconnect system
- Gold-plated phosphor bronze contacts for conductivity
- Four-wall shielding for EMI protection
Applications
- Board-to-board connections
- Cable to board interconnections
- High-density electronic assemblies
Procurement Notes
Verify the specific suffix codes against official Harwin documentation to ensure correct tail length and keying options. Confirm RoHS compliance status as historical data may vary. Check for obsolescence notices or lifecycle changes before finalizing procurement plans. Ensure compatibility with mating sockets from the same Datamate L-Tek family.
Selection Notes
Select this component for applications requiring surface mount headers with high shock and vibration resistance. The 2.00mm pitch allows for dense packing while maintaining reliable electrical performance. Consider the four-wall shielded design if electromagnetic interference mitigation is required in the target environment.
Part Context
This part belongs to the Datamate L-Tek series, known for high reliability in harsh environments. It offers 100G shock, 40G bump, and 10G vibration resistance capabilities. The series supports various pitch options and termination styles, making it suitable for demanding industrial and aerospace applications.
Replacement Considerations
No direct public substitute part numbers are confirmed for this specific model. Evaluate other Harwin Datamate L-Tek variants with matching pitch and position counts for potential cross-reference.
