External synchronous input operation
When the external synchronous input terminal (9) is open (HIGH), the output
relay performs timer operation according to the input signals (LIGHT, DARK).
When the external synchronous input terminaL (9) is connected to the 0 V ter-
minal (2) (LOW), the output relay turns OFF, independently of the input signals
and output status, and acts as an inhibit signal.
DARK turns the relay ON and the transistor out-

put "H".

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
within 10 m.
•The strip-off length of the core in the connection cable should be 20
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.
•Use independent shielded wires for the Emitter and Receiver.
Using a common shielded wire can cause a malfunction.
Extension Cable
Through-beam
Reflective model
● 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.

OMRON shall not be responsible for the user's programming of a programmable product, or any consequence thereof.
Disclaimers
CHANGE IN SPECIFICATIONS
Product specifications and accessories may be changed at any time based on improvements and other reasons.
It is our practice to change model numbers when published ratings or features are changed, or when significant construction changes are made.
However, some specifications of the products may be changed without any notice. When in doubt, special model numbers may be assigned to fix or
establish key specifications for your application on your request. Please consult with your OMRON representative at any time to confirm actual
specifications of purchased products.
DIMENSIONS AND WEIGHTS
Dimensions and weights are nominal and are not to be used for manufacturing purposes, even when tolerances are shown.
PERFORMANCE DATA
Performance data given in this catalog is provided as a guide for the user in determining suitability and does not constitute a warranty. It may represent the
result of OMRON’s test conditions, and the users must correlate it to actual application requirements. Actual performance is subject to the OMRON
Warranty and Limitations of Liability.
