This is a very rugged, and robust sensor. In our Cortado MkIII promotion video we show this sensor being run over by a car without suffering any damage. This is the senor you need if your Cortado MkII application requires something less fragile than the stock option.
We hand make each of these sensors in our Chicago lab, and they are all tested using the same digital analyzation QA procedure that we use for the Cortado MkIII. Installation instructions are in the Cortado MkII manual.
