Precautions on Moving Coils with Polarity Sensors
When you use a Moving Coil with a Polarity Sensor, the Magnetic Way must cover the bottom
of the polarity sensor. Refer to the example that shows the correct installation.
When determining the length of the Moving Coil’s stroke or the length of the Magnetic Way,
consider the total length (L) of the Moving Coil and the polarity sensor. Refer to the following
table.
