(1) Operation Mode Selector
(1) Operation Mode Selector
AUTO Mode: The sensitivity is automatically adjusted within a range
of approximately 80% to 110% of the rated sensing
distance. Except for the E2CY-C1R5A-1, which is
adjusted within approximately 60% to 110% of the
rated sensing distance.
T Mode:
This mode is used when adjusting the sensitivity of the
Sensor.
(The output transistor does not operate in this mode.)
RUN Mode: This mode is used for the normal operation of the
Sensor.
(2) Resolution Selector
If the E2CY often has a teaching error when detecting fine
differences, set the resolution selector to FINE. The response speed
will drop but improvement in the sensing precision of the E2CY can
be expected.
(3) Output Mode Selector
(Pre-wired cable end)
(3) Output Mode Selector
Used to select the transistor mode of the NPN open-collector output.
NO: Normally open output (Output transistor will turn ON if a sensing
object is present.)

Safety Precautions
Refer to Warranty and Limitations of Liability.
WARNING
● Mounting
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 excessive force when tightening the nuts on the E2CY@. A toothed washer must be used with the nut.

• Mounting Unthreaded Cylindrical Models
When using a set screw, tighten it to a torque of 0.2 N·m max.
When mounting the Sensor within a
metal panel, ensure that the
clearances given in the following
table are maintained. Failure to
maintain these distances may cause
deterioration in the performance of
the Sensor.

● Adjustment
Power ON
The Sensor is ready to sense an object within 50 ms after turning the
power ON.
If the load and Sensor are connected to different power supplies,
always turn ON the Sensor power first.
Teaching
Make sure that the Sensor is in operating condition before making
sensitivity adjustments.
Processing the Sensor Cable Ends
When cutting or extending the cable, the end of the Sensor cable
connected to the E2CY-@ must be processed as shown in the
following illustration.
Sensor cable
Mutual Interference
When installing Sensors face-to-face or side-by-side, ensure that the
minimum distances given in the following table are maintained.
*1. Be sure to turn over the braided shield so that
none of its thin wires are left.
*2. Make sure that an insulation distance of at least
2.5 mm is maintained.

Effects of a High-frequency Electromagnetic Field
If the Sensor is located near a device that generates high frequencies
or a transceiver, it may be affected by such a device and malfunctions
may occur.
The self-diagnostic output transistor will turn ON in the following
cases.
(1)Sensor Open Circuit:
Output will turn ON 105 ms after the Sensor circuit opens.
(2)Sensor Short Circuit:
Output will turn ON 105 ms after the Sensor circuit shorts.
(3)Control Output Short Circuit:
Output will turn ON when both ends of the control output (load) are
shorted and an overcurrent flows.
(4)Internal Memory Error:
Output will turn ON when the teaching conditions cannot be
recorded in internal memory when power is turned ON in RUN or
TEACH mode.
