Turbosmart GenV HE 'Hall Effect Sensor' is a non-contact position sensor, supplied with calibration data for use with all GenV External Wastegates (fitted with the sensor cap), including RacePort BOV and GenV Anti Lag Valve (ALV40).
The Non-Contact Hall Effect Sensor Design allows the caps to be manufactured with a blind hole, meaning it is not a through-the-hole & as such, not prone to leaking or being subjected to heat like other solutions.
