TPZS
True Position Zero Speed sensor with DHE technology for motorsport use.
The TPZS sensor uses Differential Hall Effect sensing with signal conditioning for thermal compensation and true zero‑speed operation. It detects ferromagnetic teeth via a changing magnetic field, with an internal magnet removing the need for external magnets. It operates down to 0 Hz for accurate low‑ or zero‑speed detection, and its compact, hard‑anodised aluminium body is resistant to vibration, fluids, and high temperatures—ideal for motorsport use.
