What are the key features of M80-8400342?
- 3-position SIL 3.2 mm pitch through-hole receptacle with gold-plated mating contacts ensures low contact resistance and extended durability over repeated mating cycles
- Polarized housing prevents incorrect connector orientation during assembly, reducing wiring errors in field-installed and field-replaced board assemblies
- Datamate L-Tek series compatibility with a broad family of plugs, housings, and cable assemblies simplifies multi-board and backplane interconnect system design
What is M80-8400342 used for?
The M80-8400342 is used in industrial control boards, instrumentation panels, and embedded computing modules where a compact 3-position single-row through-hole receptacle provides reliable board-to-wire or board-to-board connectivity. Its 3.2 mm pitch and polarized Datamate L-Tek housing suit defense electronics, aerospace subsystems, and test equipment requiring positive mating verification and high retention force. The gold-plated contacts also make it suitable for low-level signal connections where contact resistance stability over temperature cycles is critical.

Frequently Asked Questions
What pitch and contact finish does the Harwin M80-8400342 use, and how do they affect performance?
The M80-8400342 uses a 3.2 mm pitch with gold-over-nickel mating contacts and tin-plated through-hole termination pins. The 3.2 mm pitch provides 3 positions in a compact 9.6 mm total length, while the gold contact finish (typically 0.38 µm or 15 µin) ensures low and stable contact resistance for signal-level connections over thousands of mating cycles in industrial and instrumentation applications.
How does the polarized housing of the M80-8400342 prevent assembly errors in PCB production?
The Datamate L-Tek polarized housing features an asymmetric keying feature that physically prevents the mating plug from being inserted in the wrong orientation. This polarization eliminates reversed-polarity failures during manual and automated cable assembly, which is especially important in 3-position connectors where an incorrect connection could damage power or signal circuits on the PCB.
For which applications is the M80-8400342 better suited than a standard 2.54 mm pitch connector?
The M80-8400342 with its 3.2 mm pitch is better suited for applications requiring higher current capacity per contact (typically up to 3 A per pin) and greater mechanical robustness than standard 2.54 mm (0.100 inch) pitch connectors provide. It is preferred in defense electronics, industrial control enclosures, and vibration-prone environments where the larger pitch and locking Datamate housing withstand mechanical stress and connector retention requirements that standard 2.54 mm connectors cannot meet.
Which Harwin Datamate L-Tek mating connectors and cable assemblies are compatible with the M80-8400342 receptacle?
The M80-8400342 SIL straight receptacle mates with Harwin M80 series plugs and crimp housings at 3.2 mm pitch, including the M80-8530000 series cable end plug housings accepting 26 to 30 AWG wire with 3 A per contact rating. The Datamate L-Tek family offers pre-assembled cable assemblies in standard lengths, reducing integration time for 3-position SIL signal and power wiring harnesses in industrial and defense board-level assemblies.
