Electrical output 4.3151.x0.012 4.3151.x0.110

With electronic protective circuit which circuit avoids an overloading of the potentiometer in case of erroneous connection and on transition 0° → 360°The protective circuit represents a nominal series R=50 Ω. However it limits the short-circuit-current on transition from 0° → 360 ° (and vice versa)

to ≤1 mA at Pot=10 kΩ and ≤2 mA at Pot=2 kΩ

Linearity

0.25% (1°)
