Overview
The Harwin M80-8412042 is a Datamate L-Tek series board connector, specifically a horizontal 90-degree tail plug assembly. It features a single row with four contacts and a 2mm pitch. The unit supports a current rating of 2.2A and a voltage rating of 120V. Contact finish thickness on the post is specified as 118.1µin (3.00µm). The housing utilizes PPS material, and the system is designed for board-to-board and wire-to-board applications.
Feature Summary
- Horizontal 90-degree tail plug configuration for space-constrained mounting
- Datamate L-Tek series design ensuring secure board-to-board and wire-to-board connections
- Single-row architecture with four contacts for compact signal routing
Applications
- Board-to-board interconnects in industrial control modules
- Wire-to-board connections within electronic enclosures
- Compact device integration requiring right-angle PCB mounting
Procurement Notes
Verify the specific contact finish thickness requirements against the application's environmental conditions. Confirm that the 2.2A current rating aligns with the circuit load. Ensure the horizontal 90-degree orientation matches the mechanical layout constraints of the target PCB assembly to avoid clearance issues.
Selection Notes
Select this component when a low-profile, right-angle connection is required for four signals. The Datamate L-Tek series offers robust locking mechanisms suitable for vibration environments. Consider the 2mm pitch spacing relative to adjacent components on the PCB to ensure adequate soldering access and mechanical stability during operation.
Part Context
This part belongs to the Harwin Datamate L-Tek family, known for high-density interconnect solutions. The M80-8412042 variant specifically addresses needs for horizontal mating configurations. It complements vertical and straight variants within the same ecosystem, providing design flexibility for complex multi-layer PCB layouts and tight spatial requirements.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation.
