OUTLINE
This product is a sensor head for connecting to a Electrostatic sensor controller
(EF-S1C).
It can be used for in-line measurement of electrical potentials on object surfaces.

MOUNTING
A protective seal is affixed to the measuring part of
this product at the factory setting. Be sure to remove
this protective seal before use.
Do not let any dust or other foreign materials get
onto the sensor. If dust or other foreign materials get
onto the measuring part or the area around it, it may
interfere with correct measurement. If dust or other
foreign materials get onto the sensor, clean it off
with an air blower or similar.
Use M3 pan-head screws, spring washers and plain
washers (please arrange separately) to mount the
sensor so that it faces downward. The tightening
torque at this time should be 0.5N . m or less.
Example of recommended mounting
If a mounting bracket used by
the customer is brought close to
the measuring part, it may affect
measuring performance.
Mount the mounting bracket to
the sensor head so that it is as
far away from the measuring
part as possible.
If a charge builds up in the mounting bracket, it will affect measuring performance,
so be sure to ground the mounting bracket when using the sensor. However, the
metal enclosure should be insulated.
Mount in a location which is not subject to vibration.
Mount the sensor head so that the sensor is parallel to the object being measured,
and use the exclusive controller (EF-S1C) to set the measuring distance so that it
is equal to the distance from the sensor to the object being measured.
(Measurement accuracy will be better if the measurement distance is set to as
short a distance as possible.) For details on the setting method for the controller,
refer to the separate instruction manual for the exclusive controller (EF-S1C).

This product measures electric fields. Because of this, if any objects are present
inside the measurement area (refer to the illustration below) or near the sensor
head which might disturb the electric field around the object being measured, it
will affect measurement accuracy.
(
The shorter the measurement distance, the more difficult it will be for nearby
objects to have an adverse effect on measurement.
In order to obtain the most accurate measurement results, mount the sensor head
while taking into account factors such as the measurement distance,
measurement area and ambient environment.
In addition, after mounting the sensor head, carry out 0-Adjust and calibration
using the controller. For details, refer to the separate instruction manual for the
exclusive controller (EF-S1C).

Measurement area (mm)
If several sensors are being used together, measurement errors will occur
because the metallic parts of the sensor heads will act as nearby metallic objects
that can affect measurement.
Mount the sensors so that there is a gap between them that is equal to or greater
than the values given in the table below.

CONNECTION TO EXCLUSIVE CONTROLLER(EF-S1C)
Be sure to turn off the power before connecting the sensor head and the exclusive
controller.
How to mount the sensor head to the controller
Insert the sensor head connector into the inlet of
the exclusive controller until it clicks.
Fit the connector cover on the connector.
When removing the sensor head, be sure to push
down the connector lock lever while removing it. If
the connector is pulled with excessive force (0.4N
or more) without the lock lever being pushed
down, it may damage the connector.
