Key Features
- 2-position polarised SIL receptacle at 3.2 mm pitch prevents mis-mating, ensuring correct signal polarity in power and signal connections on compact PCBs
- Gold and tin contact finish combination on mating surfaces provides reliable low-resistance connections with a nickel barrier layer to prevent tin whisker migration
- Straight through-hole termination in a compact 0.281-inch body suits dense PCB layouts where only 2 positions are needed for power or I2C connections
Applications
The M80-8400242 is designed for 2-wire power distribution, sensor signal lines, and I2C or UART connections in industrial electronics, robotics, and embedded control boards where a compact polarised connector prevents incorrect wiring. Its through-hole straight mounting secures the connector against vibration in moving machinery applications. The Datamate L-Tek series provides reliable connections in harsh-environment designs where 2-pin connectors must withstand mechanical stress.

Frequently Asked Questions
What pitch and position count does M80-8400242 use, and why is polarisation important for its typical applications?
The M80-8400242 has 2 positions at 3.2 mm pitch in a single-in-line layout. Polarisation is critical for 2-pin power connectors because reversing polarity on 2-wire connections can damage components instantly; the polarised housing physically prevents reversed insertion, protecting circuits operating at supply voltages up to the connector's rated level.
How does the gold and tin contact finish with nickel barrier on M80-8400242 improve long-term connection reliability?
The M80-8400242 uses tin termination with a nickel barrier layer that blocks tin-copper intermetallic growth, extending solder joint life beyond 1000 hours at elevated temperature, while the gold finish on mating contacts maintains sub-milliohm contact resistance across hundreds of mating cycles in industrial environments.
When is the through-hole straight SIL format of M80-8400242 preferable over SMD 2-pin connectors for vibration-prone designs?
In robotics, motor control boards, and automotive auxiliary modules subject to continuous vibration above 5 g, the through-hole straight mounting of M80-8400242 mechanically anchors the connector body through the PCB with soldered leads in each of its 2 positions, whereas surface-mount pads can fracture under repeated mechanical stress with no through-board reinforcement.
