Novotechnik Hollow-shaft angle sensors

The WAL 200 Series of hollow-shaft angle sensors provide absolute rotary position. Sensor dimensions are 7 by 22 mm. The series has a measurement range of 0 to 340°. Mechanical range is a continuous 0 to 360°. Other specifications include resolution of < 0.3°, repeatability of 0.3° and independent linearity of ±1% of measurement range. As an absolute sensor, the sensors continue to track angle even if power is removed, reporting the correct position when power is restored. They have a minimum life of two million mechanical movements. Cable and connector versions are available.
