Overview
The M80-5L12642MC is a vertical board-to-board header from the Datamate L-Tek series by Harwin Inc. It features a 2-row configuration with 26 positions and a 2.00mm mating pitch. The connector utilizes through-hole termination for PCB mounting and employs push-pull locking mechanisms. Contact materials are phosphor bronze with gold plating on mating surfaces, while pins are tin-plated. The housing is constructed from black glass-filled polyphenylene sulfide (PPS) rated UL94 V-0. Rated current is 3A at 120V, operating within -55°C to 125°C.
Feature Summary
- Push-pull locking mechanism ensures secure connection retention
- Glass-filled PPS insulation provides high thermal stability
- Gold-plated contacts ensure reliable signal transmission
- Vertical orientation facilitates direct PCB integration
Applications
- Industrial control system interconnections
- Telecommunications equipment backplanes
- Automotive electronic module interfaces
- Medical device internal circuitry connections
Procurement Notes
Verify the specific ordering suffix against the official Harwin datasheet to confirm pin count, row configuration, and termination style. Ensure compatibility with corresponding Datamate L-Tek female connectors. Confirm RoHS compliance status if required for specific regulatory environments. Check lead times as standard delivery periods may vary based on production schedules.
Selection Notes
Select this component when vertical mounting space is constrained but robust mechanical locking is required. The 2.00mm pitch suits moderate density applications. Verify that the mating connector supports the push-pull locking interface. Ensure the PCB footprint matches the through-hole pin dimensions specified in the CAD models.
Part Context
This part belongs to the Datamate L-Tek family, designed for high-reliability applications requiring secure mechanical retention. Unlike standard slide-lock variants, the L-Tek series incorporates a push-pull locking feature to prevent accidental disengagement during vibration or shock. It complements the broader Datamate ecosystem of rectangular connectors.
Replacement Considerations
Direct substitutes must match the 26-position, 2-row, 2.00mm pitch specification and push-pull locking mechanism. Cross-reference with other Harwin Datamate L-Tek headers. Generic rectangular connectors lacking the specific locking interface are not suitable replacements without mechanical redesign.
