Function description:
Contactless inductive sensor with two transistor switched outputs. The output OUT 2 is inverted. The double output signal is protected against
mutual interference and increases the reliability of the spool end position signalization, which is important for the command system ensuring the
safety of the machine operation. The sensor is factory set to switch when the spool is moved from its base position by 0.5 ± 0.1 mm. The relative
position of the encoder parts after adjustment is indicated in red. The electrical connection of the sensor is provided by a four-pin connector with
M12x1 thread.
