We have shipped our first Version 2 sensors. We have enough stock for all pre-orders, so, if you have paid, you should have your sensors by the end of the coming week.
We test each sensor against a known sensor. We have also tested mating and demating the tiny MHF 4 connector. These appear to work for around 40 disconnections if used carefully, and the signal integrity remains constant. We would recommend obtaining a connector removal tool (I-PEX 90435-001) if you plan to re-use sensors.
