Comment
Smallest error by pedal idle position (0°)
High immunity against temperature
variation
Flexible and easy assembly thanks to
Modulo 90 feature
Smallest error for small angles or linear
movement / with digital output / version
with redundancy function available soon
Application requires measurement of
40 mm movement, highest accuracy
achievable with HAL 37xy
1% full-scale error required by application
Price-sensitive application & analog out-
put standard interface for this application
Usual angular range is above 120°,
highest accuracy achievable with
HAL 37xy
360° application & digital output
Small-angle application & SENT protocol
/ version with redundancy function avail-
able soon
Highest angle accuracy for 120°
& simple magnetic circuit
High temperature stability and output
signal flexibility (analog and PWM)
All compensation (sensitivity / offset,
etc.) will be done by ECU software.
Low-end linear sensor is required.
Application requires measurement of
40 mm movement, highest accuracy
achievable with HAL 37xy
Application requires measurement of
40 mm movement, highest accuracy

2D required, because usual detection
angle is >180°. Next step will be full
gear detection.
