As a result of the SPG (Smart
Process Gating) method developed
by Leuze electronic, signal-emitting
sensors are no longer needed.

With SPG, the first muting signal
comes from the process control

requires a detailed knowledge of the
process so that the necessary SPS
control signals are made available in
the expected time window.
