Battery-Buffered Hall Multiturn Encoder

iC-PV is an ultra low power encoder with up to 40 bit Multiturn and 3 bit Singleturn resolution.

In case of power failure iC-PV automatically switches to battery supply and continues to count the multiturn position. Integrated monitoring signalizes an empty battery. iC-PV supports angular accelerations up to 760 000 rad/s2 at a speed of 120 000 rpm. Together with a singleturn IC a complete multiturn encoder system can be realized.
