Overview
The Harwin M83-LMT1M1N54-0000-000 is a Datamate J-Tek board connector featuring 54 contacts arranged in a 3-row male configuration. It utilizes a 2 mm pitch and straight solder terminals for PCB mounting. The contacts are gold-plated phosphor bronze, designed for reliable signal transmission. This component includes internal threaded jackscrews for secure mating retention.
Feature Summary
- Datamate J-Tek series with 3-row male contact arrangement
- Gold-plated phosphor bronze contacts for durability
- Internal threaded jackscrew mechanism for secure locking
- Straight through-board solder termination
Applications
- Industrial control systems requiring high-density interconnects
- Test and measurement equipment interfaces
- Medical device hardware connections
- Automotive electronics assemblies
Procurement Notes
Verify the specific suffix codes against the official Harwin datasheet to confirm jack screw type and tail length. Ensure compatibility with corresponding female receptacles within the Datamate J-Tek family. Confirm RoHS compliance status for your region before finalizing procurement orders.
Selection Notes
Select this part when a 54-contact male header with internal jackscrews is required. Verify that the 2 mm pitch matches the mating connector footprint. Consider the straight orientation for standard vertical PCB mounting applications where space allows.
Part Context
This component belongs to the Harwin Datamate J-Tek line, known for high-reliability interconnects. The M83 prefix indicates a specific housing and contact combination within the broader connector ecosystem. It is designed for harsh environments requiring robust mechanical retention.
Replacement Considerations
Direct substitutes must match the 3-row, 54-pin, male specification with internal jackscrews. Cross-reference with other Harwin M83 variants only if pin count and gender align. Generic connectors lack the specific jackscrew retention mechanism.
