Typical connection diagram and ground plane
Good EMC practice requires the use of ground planes on PCBs. In drives where high dV/dt transients are present, a ground
plane between the primary conductor and Minisens will reduce or avoid output perturbations due to capacitive currents.
However, the ground plane has to be designed to limit eddy currents that would otherwise slow down the response time.
The effect of eddy currents is made negligible by cutting the copper plane under the package as shown in figure 7:
LEM reserves the right to carry out modifications on its transducers, in order to improve them, without prior notice.
