M83-LML3M1N54-0000-000

Overview

The M83-LML3M1N54-0000-000 is a Datamate J-Tek header and wire housing component manufactured by Harwin. It features a 3-row, 54-pin female configuration with vertical through-board mounting. The connector utilizes a 2 mm pitch and includes gold-plated phosphor bronze contacts for reliable signal transmission. It is designed with a 3 mm printed circuit board tail length and incorporates internal threaded jackscrews for secure mating. This shrouded assembly supports high-reliability applications requiring robust mechanical retention.

Feature Summary

• Vertical through-board mounting design with integrated PCB tails
• Internal threaded jackscrew mechanism for secure mating retention
• Gold-plated phosphor bronze contacts ensuring corrosion resistance
• Shrouded 3-row housing structure providing contact alignment

Applications

• Aviation electronic systems
• Defense equipment interconnects
• Industrial control modules
• Medical critical electronic equipment
• Space and UAV applications

Procurement Notes

Verify the specific ordering suffix to confirm pin count, row configuration, and termination style match the design requirements. Ensure compatibility with corresponding male connectors within the Datamate J-Tek series. Confirm RoHS compliance status via the official datasheet before finalizing procurement. Cross-reference the manufacturer part number with distributor listings to avoid substitution errors.

Selection Notes

Select this component when vertical mounting with fixed PCB tail length is required. The 54-pin capacity suits high-density signal routing needs. Verify that the mating environment accommodates the jackscrew retention method. Consider the 2 mm pitch constraints for trace spacing on the host printed circuit board during layout planning.

Part Context

This component belongs to the Datamate J-Tek series, known for high-reliability performance in harsh environments. The series offers various configurations including headers, cable assemblies, and crimp contacts. The M83 prefix indicates a specific header variant within the broader Datamate ecosystem designed for secure, vibration-resistant connections.

Replacement Considerations

Compatible substitutes include other Harwin Datamate J-Tek headers with matching 3-row, 54-pin specifications. Verify identical pitch, termination type, and retention mechanism before substitution. Generic equivalents are not recommended due to strict dimensional and electrical tolerances required for jack screw engagement.
