M80-4T11842F2-00-000-03-321

Headers, Receptacles, Female Sockets Overview

The Harwin M80-4T11842F2-00-000-03-321 is a DataMate L-Tek board connector featuring 21 contacts in a female configuration. It utilizes a mixed contact arrangement with 18 signal and 3 power positions. The component employs a vertical orientation with solder terminals and a black glass-filled polyphenylene sulphide insulator. Key electrical parameters include a contact resistance of 25 mΩ, an insulation resistance of 100,000,000 Ω, and a durability rating of 500 cycles. The housing dimensions are 2.205 inches in length, 0.219 inches in width, and 0.205 inches in depth.

Headers, Receptacles, Female Sockets Feature Summary

• Mixed signal and power contact configuration for combined data and energy transmission
• Locking mechanism with jack screw installation option for secure mating
• Vertical board mounting design with straight solder termination
• High insulation resistance and durable beryllium copper contact material

Headers, Receptacles, Female Sockets Applications

• Industrial control systems requiring robust signal and power connections
• Automotive electronics assemblies needing reliable board-to-board interfaces
• Test and measurement equipment demanding high-cycle durability connectors

Headers, Receptacles, Female Sockets Procurement Notes

Verify the specific contact plating finish (tin or gold) as this varies by suffix within the M80 series. Confirm that the jack screw locking feature aligns with the mechanical constraints of the target assembly. Ensure the vertical orientation and pin layout match the PCB footprint requirements before finalizing procurement orders to avoid integration issues.

Headers, Receptacles, Female Sockets Selection Notes

Select this part when a mixed signal and power interface is required in a vertical form factor. The 2.00mm/4.00mm pitch supports both standard signal lines and higher current power paths. Consider the 500-cycle durability rating against the expected mating frequency of the application environment to ensure long-term reliability.

Headers, Receptacles, Female Sockets Part Context

This component belongs to the Harwin DataMate L-Tek family, designed for high-reliability applications. The M80 series is characterized by its modular construction and mixed contact capabilities. This specific model represents a standard plug variant intended for direct board mounting, offering a compact solution for dense electronic interconnections.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes may include other Harwin DataMate L-Tek variants with matching 21-position layouts. Verify compatibility regarding the locking mechanism type and terminal plating specifications. Cross-reference the housing dimensions and pin assignment to ensure mechanical and electrical interchangeability without redesigning the host PCB.
