PROTECTIVE COVER CARE
Cover Screw: The torque of the
cover screw must not exceed
3.5 kg-cm (3 in-lb). Over-torquing
will cause the plastic parts to
crack.

SENSITIVITY ADJUSTMENT
Wiring
Separating the sensor line from inductive or noisy
power lines is recommended.
Output Protection Circuit
The protection circuit below increases reliability by
protecting the sensor output from surge or noise.
By utilizing the constant-voltage characteristic of a surge
absorber, this circuit prevents high voltages from being
applied across the contacts.
This circuit, if connected across the load, is effective
when the supply voltage is 24 to 48 V. If the supply
voltage is 100 to 240 V, connect the circuit across the
contacts.
Employ a diode having a reverse breakdown voltage of
more than 10 times the circuit voltage and a forward
current rating greater than the load current. A diode
having a reverse breakdown voltage two to three times
that of the supply voltage can be used in an electronic
circuit where the circuit voltage is not particularly high.
CONNECTION OF AMPLIFIER
AND FIBER CABLE
E3JU-X
4 -
Uses E32-U B series fiber optic cable with grooved
tip (4.75 mm dia).
Make sure the clamp is raised in the unlocked
position.
Firmly insert the fiber optic cable tips into the
amplifier.
Move the clamp down to the locked position (the
ridges in the clamp should slide into the grooves of
the tips and hold the fiber cables in place).
To remove the fiber cables, raise the clamp to the
unlocked position and carefully pull the fiber cables
out of the unit.
E3JU-XR
4 -
Uses E32 series fiber optic cable (2.2 mm dia or
1 mm dia with E39-F9 adapter). Must use fiber that can
be inserted 15 mm into amplifier to meet sensing
distance spec.
Make sure the clamp is rotated in the unlocked
position.
Carefully insert the fiber optic cable into amplifier,
approximately 14.0 mm (0.55 in).
Rotate the clamp to the locked position to secure the
fiber cables in place.
To remove the fiber cables, rotate the clamp to the
unlocked position and carefully pull the fiber cables
out of the unit.
Diffuse reflective type
Place the target object in the desired position for detection
and set the sensitivity adjustment to maximum.
Maximum stability is achieved by varying both horizontal
and vertical alignment of the fiber until it is in the center of
a range in which both the LIGHT (red) and STABILITY
(green) indicators illuminate (Light-ON mode).
Remove the object and ensure the LIGHT indicator turns
off and the STABILITY indicator illuminates. If the LIGHT
indicator does not turn off, decrease the sensitivity and
check that there is no other object in line with the fiber.
Ensure the STABILITY indicator illuminates in both
detecting and non-detecting states (refer to the table
below).
Through-beam
Turn the sensitivity adjustment to maximum.
Position the fiber optic cable ends opposite to each other and
adjust the horizontal and vertical alignment until the
STABILITY indicator (green), LIGHT indicator (red) and
OUTPUT indicator (yellow) turn on (Light-ON mode).
Once the desired position is set, introduce the object to the
beam pattern and ensure that the LIGHT and OUTPUT
indicators turn off and the STABILITY indicator illuminates.
If the LIGHT and OUTPUT indicators do not turn off, decrease
the sensitivity until the desired result is achieved.
Ensure that the STABILITY indicator illuminates in both
detecting and non-detecting states. (Refer to the table below.)
