5.1.3
Precautions on Moving Coils with Polarity Sensors
(Hall Sensor)
When you use a Moving Coil with a Polarity Sensor (Hall Sensor), the Magnetic Way must cover
the bottom of the polarity sensor (hall sensor). Refer to the example that shows the correct instal-
lation.
When determining the length of the Moving Coil’s stroke or the length of the Magnetic Way, con-
sider the total length of the Moving Coil and the polarity sensor (hall sensor). Refer to the follow-
ing table.
