Overview
The M80-8810442 is a Datamate L-Tek series PCB header manufactured by Harwin Inc. It features a male contact configuration with 4 positions arranged in a single row (SIL). The connector utilizes a 2 mm pitch and is designed for vertical through-hole mounting on printed circuit boards. It employs a friction latch mechanism for secure mating. The contacts are tin-plated, and the housing is constructed from polyphenylene sulfide (PPS). This component supports board-to-board and wire-to-board interconnection systems.
Feature Summary
- Datamate L-Tek series design with friction latch retention
- Vertical single-row male pin configuration for PCB mounting
- Tin-plated phosphor bronze contacts housed in PPS insulation
Applications
- Board-to-board interconnections
- Wire-to-board connections
- General electronic assembly requiring secure latching
Procurement Notes
Verify the specific suffix '442' to confirm the 4-position count and tin plating specification. Ensure the vertical orientation matches the mechanical layout requirements. Confirm that the friction latch style is suitable for the intended mating force and environmental conditions compared to jackscrew alternatives.
Selection Notes
Select this part when a low-profile, vertically mounted male header with positive locking is required. The 2 mm pitch allows for dense packing while maintaining adequate spacing. The tin plating offers cost-effective conductivity for general applications where gold plating is not strictly necessary for corrosion resistance or high-cycle durability.
Part Context
This component belongs to the Datamate L-Tek family, which provides modular connectivity solutions. The M80-8810442 represents the standard unlatched or friction-latch variant within the SIL male pin range. It complements female receptacles and cable assemblies within the same 2 mm pitch ecosystem to form complete interconnect chains.
Replacement Considerations
M80-8520642 is listed as a potential replacement or related product in distributor records, though it specifies a 6-position count. Verify position count compatibility before substitution.
