data sheet 3 2000-07-01 ksy 46 connection of a hall sensor with a power source since the voltage on the component must not exceed 10 v, the connection to the constant current supply should only be done via a short circuit by-pass. the by-pass circuit-breaker shall not be opened before turning on the power source. this is to avoid damage to the hall sensor due to power peaks.
