Overview
The Harwin M83-LML3M1N18-0000-000 is a Datamate J-Tek series header and wire housing component. It features a 3-row configuration with 18 contacts (6 per row). The connector utilizes male pin contacts with gold plating for reliable signal transmission. It is designed for horizontal surface-mount installation with a solder tail length of 4mm. The unit includes integrated jackscrews to secure mating connections, ensuring stability in high-vibration environments.
Feature Summary
- Horizontal surface-mount design with 4mm solder tails
- Integrated hexagonal slotted jackscrews for secure locking
- Gold-plated phosphor bronze male pin contacts
- Shrouded 3-row construction for precise alignment
Applications
- Industrial control systems requiring robust interconnects
- Medical equipment needing reliable signal paths
- Defense and aerospace electronic assemblies
- Automotive embedded systems
Procurement Notes
Verify the specific ordering suffix against the official Harwin datasheet to ensure correct contact count, orientation, and jackstyle. Confirm RoHS compliance status and REACH SVHC declarations prior to procurement. Check current lifecycle status as discontinued items may require alternative sourcing strategies or last-time buys.
Selection Notes
Select this component when a horizontal board-mount solution with mechanical locking is required. Ensure the mating cable assembly or header supports the 2mm pitch and 3-row format. Verify that the PCB footprint accommodates the 4mm tail length and that the application environment does not exceed the specified temperature range for the polyphenylene sulfide insulator.
Part Context
This part belongs to the Datamate J-Tek family, known for high-reliability performance in harsh conditions. The M83 prefix indicates the specific connector series within the Harwin portfolio. It is designed for applications where vibration resistance and secure mating are critical, utilizing internal threaded jackscrews for positive retention.
Replacement Considerations
No direct public substitute part numbers are confirmed for this specific variant. Due to the discontinued status, engineers should evaluate compatible Datamate J-Tek headers with similar 3-row, horizontal, and jackscrew configurations from the same manufacturer.
