Overview
The M83-LML3M5N54-0000-000 is a Datamate J-Tek header connector manufactured by Harwin Inc. It features a 54-position configuration with a 2mm row spacing and 3 rows. The component utilizes male pins with gold plating for reliable signal transmission. Designed for right-angle through-board mounting, it incorporates internal threaded jackscrews to secure mating connections. The housing is constructed from black polyphenylene sulfide (PPS) material, providing durability in demanding environments.
Feature Summary
- Integrates internal threaded jackscrews for secure mechanical locking
- Utilizes gold-plated phosphor bronze contacts for conductivity
- Features shrouded design with keying options for alignment
Applications
- Industrial control systems requiring high-reliability interconnects
- Test and measurement equipment interfaces
- Automotive electronics applications
Procurement Notes
Verify the specific ordering suffix against the official Harwin datasheet to ensure correct pin count, orientation, and termination style. Confirm that the required jack screw type matches the component specification. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current availability status before finalizing procurement orders.
Selection Notes
Select this component when a high-density 54-position connection is required in a compact form factor. Ensure the mating connector supports the same 2mm pitch and row configuration. Verify that the PCB layout accommodates the right-angle profile and the necessary clearance for the integrated jackscrew mechanism during assembly and operation.
Part Context
This connector belongs to the Datamate J-Tek series, designed for high-reliability applications. The series offers various configurations including headers, sockets, and cable assemblies. This specific model represents a robust solution for board-to-board or board-to-cable connections where vibration resistance and secure locking are critical operational requirements.
Replacement Considerations
Direct substitutes within the Datamate J-Tek family include M83-LML3M1N54-0000-000 and M83-LML3M7N60-0000-000. These alternatives share identical mechanical dimensions and interface specifications but differ in pin count. Verify compatibility with existing mating components before implementation.
