Safety Precautions
Refer to Warranty and Limitations of Liability.
This product is not designed or rated for ensuring
safety of persons either directly or indirectly.
Do not use it for such purposes.
Do not use the product in atmospheres or environments that exceed
product ratings.
● Wiring
Connection of E3C-JC4P Amplifier Unit and Sensor
Always run the shielded wires of the Emitter and Receiver separately.
Also, route the sensor cable along the cable grooves of the cover and
sensor and fix it with the cover.
Connection Socket
The standard socket is the PF113A for the E3C-A and -C, and the
PYF08A, PYF08M or PY08 for the E3C-GE4. Avoid using any other
sockets since they may not satisfy the characteristics. (There will be
no problem when the STABILITY indicator turns ON)
● Wiring
Extension Cable
• The extension distance of the sensor connection cable should be
• The strip-off length of the core in the connection cable should be 20
• Use independent shielded wires for the Emitter and Receiver.
within 10 m.
mm max. on the Receiver side and 50 mm max. on the Emitter side,
and the core should be as short as possible. Avoid using the joint
terminal and connector.
Using a common shielded wire can cause a malfunction.

● Others
When the E3C is used in a place where high-frequency noise will be
generated, e.g. ultrasonic welder, grounding the 0-V terminal (on the
shield side of the connection cable) of the Receiver may avoid a
malfunction caused by induction.
