In the delivery state, the sensor connection is sealed with a lid. To obtain the IP protection class,
only the blind cap can be removed from the print head, to which the product sensor is connected.

The earthing connection on the stripper plate is a
functional earthing connection.
The wiring is always star-shaped for the "central earthing
point" of the machine / system.
(= separate cable for each component).
It is of utmost importance to ensure the connection has
low impedance as the connection (also) is a "functional
earth" connection.
This applies to all stripper plates!
This sensor is not
galvanically isolated!
For print resolution via SPS
or the like, please use one
of the available digital
inputs.
