No. These are only 5-pin F/F. Sadly, we don’t carry a 9-pin version, but you could use this 5-pin with a 4-pin version.

Aha, I’ve owned a few of these and always ended up averaging the readings as I found them noisy, and didn’t know to expect it…makes me wonder, what is the noise from? Thermal noise with the high gain...
