Overview
The M80-8681822 is a Datamate L-Tek header connector manufactured by Harwin Inc. It features an 18-position, two-row configuration with a 2.00mm (0.079 inch) pitch. Designed for through-hole right-angle mounting, this male pin connector utilizes beryllium copper contacts with a tin finish. The unit supports a voltage rating of 120V and a current rating of 2.2A. The housing is constructed from black PPS material, ensuring UL94 V-0 flammability compliance.
Feature Summary
- High-reliability four-finger beryllium copper contact technology ensures connection integrity without signal loss.
- Unlatched design facilitates rapid mating and demating processes in space-constrained applications.
- Right-angle through-hole termination allows for efficient PCB layout optimization.
Applications
- Industrial control systems requiring robust board-to-board interconnects
- Telecommunications equipment utilizing high-density signal routing
- Automotive electronics demanding reliable thermal performance
Procurement Notes
Verify the specific suffix code to confirm the tin plating variant, as gold-plated versions exist within the same series. Confirm right-angle orientation matches the target PCB footprint. Ensure compatibility with unlatched mating receptacles to prevent mechanical interference during assembly.
Selection Notes
Select this component when right-angle through-hole mounting is required for 18-channel signals. The unlatched feature suits applications where manual retention is unnecessary. Verify that the 2.2A current rating meets circuit demands. Consider the tin finish for cost-sensitive projects compared to gold alternatives.
Part Context
This part belongs to the Datamate Mix-Tek and L-Tek families, known for compact rectangular interconnect solutions. The M80 base number indicates a standard rectangular connector series. It pairs with corresponding female sockets to form complete cable or board assemblies.
Replacement Considerations
Direct substitutes include other 18-position, 2mm pitch, right-angle headers from compatible manufacturers. Ensure equivalent current ratings and contact materials are maintained. Generic equivalents may lack the specific four-finger contact geometry.
