Key Features
- 5-position single-in-line through-hole receptacle with 3.2 mm pitch for robust board-to-wire connections
- Gold (Au) plated termination contacts ensuring low contact resistance and long-term corrosion resistance in harsh environments
- Polarized body design preventing mis-mating and ensuring correct orientation during field assembly
- Straight THT mounting providing maximum mechanical retention strength on the PCB under vibration and shock loads
- Datamate L-Tek series rated for industrial and defense environments with RoHS-compliant construction
Applications
The M80-8400545 is deployed in defense electronics, avionics, and industrial control systems requiring a compact yet mechanically secure 3.2 mm pitch wire-to-board connection that withstands continuous vibration above 20 g. Medical instrument manufacturers use it to connect sensor harnesses to PCBs where gold-plated contacts must maintain under 10 mΩ contact resistance over thousands of mating cycles. It is also a standard choice for ruggedized test and measurement equipment and UAV flight controller boards where polarization prevents field-wiring errors.

Frequently Asked Questions
How many mating cycles is the M80-8400545 rated for, and does the gold plating degrade over time in humid environments?
Harwin's Datamate L-Tek connectors are typically rated for a minimum of 200 mating cycles, and the gold-plated termination contacts maintain stable contact resistance below 10 mΩ across that lifespan. Gold does not oxidize in high-humidity conditions, making the M80-8400545 reliable in environments with relative humidity up to 95% non-condensing.
What wire gauge range is compatible with the M80-8400545, and how is the wire terminated to the receptacle?
The Datamate L-Tek receptacle housings accept crimp contacts sized for 26 AWG to 22 AWG wire with an insulation outer diameter up to 1.52 mm. Crimping is performed with Harwin's dedicated M80-series crimp tool to achieve a tensile pull-out strength of at least 20 N per contact, meeting IPC/WHMA-A-620 Class 2 requirements.
Can the M80-8400545 be used in a 5 V logic signal harness, and what is its current rating per pin?
Yes. The M80-8400545 is rated for signal and low-power applications up to 1 A per contact at voltages up to 100 V AC/DC, which comfortably covers 5 V digital logic, 3.3 V sensor lines, and 12 V power leads for fan or relay control. For 5 contacts carrying 1 A each, the connector dissipates under 50 mW total at rated contact resistance.
How does the M80-8400545's 3.2 mm pitch compare to standard 2.54 mm pitch headers in terms of PCB space and durability?
The 3.2 mm pitch of the M80-8400545 results in a 5-position row length of approximately 12.8 mm, compared to 10.16 mm for a 2.54 mm pitch header. The wider pitch allows heavier-gauge wire terminations and larger contact cross-sections, delivering higher current capacity and better mechanical retention under 20 g vibration levels typical of industrial machinery.
