I'm trying to identify the mating connector for this speed sensor. The sensor in itself is a custom CNC job so no datasheet available...

It's got three pins and 5 "grooves". The exterior thread is a tad less than 1/4".

Subsidiary question : I think it is a hall sensor since it has 3 pins and the end is magnetic, any idea how to identify which pin is which?

Connector 1 Connector 2

Thanks by advance!

    \$\begingroup\$ I would describe it as a "5 notch shrouded polarized military male connector" if that helps in search engines. \$\endgroup\$

    \$\begingroup\$ What's that engraved on the connector barrel? Might be useful. Also, if you can photo the whole connector side on, some manufacturers have distinctive marking or knurling (such as Lemo's chocolate bloc). Or is that it before it joins to the sensor body? \$\endgroup\$

  • \$\begingroup\$ @Andyaka Are there Lemo connectors with a thread? I'm yet to come across a Lemo with a thread. \$\endgroup\$ Apr 30, 2020 at 19:42
