Electrostatic Sensor EF-S1
I/O Circuit and Wiring diagrams
EF-S1C[NPN output]
I/O circuit diagram
Notes:
1) |
If using together with an ionizer, the 0 V line of this product should be connected to the ionizer ground. In addition, the metal parts of the sensor head (EF-S1HS) are connected to the 0 V line, so it should be insulated during installation. |
2) |
In case of using the analog voltage output, connect a device having a input impedance of 1MΩ or more. Further, the analog voltage output does not incorporate a short-circuit protection circuit.
Do not connect it directly to a power supply or a capacitive load. |

Wiring diagram
<Points to note when using analog output>
Because the 0 V lines for judgment output and analog voltage output are common, the analog voltage output may vary depending on the load current. In order to satisfy the linearity specifications for the analog voltage output, do not use the judgment output. |
