* = consider the voltage loss of the cable; the excitation voltage 5 V ± 5% of the sensor must be
guaranteed.
Note: For longer distances (see specification above) you must use min. 0.5 mm² wire for „Excitation+“
and „Excitation GND“ (see signal wiring next page), all signal wires must be min. 0.14 mm²!
