Overview
The M83-LML3M7N18-0000-000 is a Datamate J-Tek header assembly manufactured by Harwin. It features a 2 mm pitch, three rows, and eighteen male pin contacts. The connector utilizes phosphor bronze contacts with gold plating for reliable signal transmission. Designed for right-angle surface mount installation, it includes a 4 mm tail length for PCB termination. The unit operates within a temperature range of -55°C to 125°C and meets UL94 V-0 flammability standards.
Feature Summary
- Shrouded design ensures correct mating alignment and prevents short circuits
- Integrated mounting flange provides mechanical stability during operation
- Gold-plated phosphor bronze contacts offer corrosion resistance and conductivity
Applications
- Industrial control systems requiring robust interconnects
- Test and measurement equipment interfaces
- Automotive electronics modules
Procurement Notes
Verify the specific ordering suffix matches the required contact count and tail length. Confirm RoHS compliance status through official manufacturer documentation before integration. Ensure PCB footprint dimensions align with the specified 2 mm pitch and shrouded housing geometry to guarantee proper assembly and electrical performance.
Selection Notes
Select this component when a high-density, right-angle header is required for space-constrained designs. The three-row configuration supports increased I/O density compared to single or dual-row alternatives. Verify that the operating temperature range and current ratings meet the specific application requirements for long-term reliability.
Part Context
This part belongs to the Datamate J-Tek series, known for its compact size and high durability. The M83 prefix indicates a horizontal PC-tail header assembly. The product line is widely used in applications demanding reliable connections in harsh environments, offering a balance of performance and mechanical strength.
Replacement Considerations
Direct substitutes include other Harwin Datamate J-Tek headers with identical 2 mm pitch and three-row configurations. Ensure any replacement maintains the same contact material, plating thickness, and mounting style to preserve mechanical and electrical compatibility.
