Fiber Unit Connection
The E3X Amplifier Unit has a lock button for easy connection
of the Fiber Unit. Connect or disconnect the fiber units using
the following procedures:
1. Connection
Open the protective cover and raise the lock lever to release
the lock. Next, insert the fiber units according to the fiber unit
insertion marks on the side of the Amplifier Unit, and lower the
lock lever.
Note: If one of the fibers from the Fiber Unit is labeled as the Emitter fiber, such as
with a Coaxial Sensor, insert that fiber into the Emitter section. Refer to
Dimensions for the Fiber Unit
to see if there is an Emitter fiber label.
2. Disconnecting Fiber Units
Remove the protective cover and raise the lock lever to pull
out the fiber units.

Adjusting
Mutual Interference Protection Function
Light from other sensors can cause the value on the digital
display to become somewhat unstable. If this occurs, reduce
the threshold to create a greater margin and enable more
stable detection.
Output Short-circuits Protection
OVER/CUR will flash on the display if the output short-circuit
protection function operates due to a load short-circuit in a
control output. If this occurs, check the load connections.
EEPROM Writing Error
If the data is not written to the EEPROM correctly due to a
power failure or static-electric noise, initialize the settings with
the keys on the Amplifier Unit. ERR/EEP will flash on the
display when a writing error has occurred.
Optical Communications
Several Amplifier Units can be slid together and used in
groups. Do not, however, slide the Amplifier Units or attempt
to remove any of the Amplifier Units during operation.

Protective Cover
Always keep the protective cover in place when using the
Amplifier Unit.

Design Precautions
Applicable Fiber Units
Refer to the sensing distance tables on pages 5 to 7 for the
Fiber Units that can be used and the sensing distances.
Retro-reflective, Convergent-reflective, Ultra-compact, and
Application-specific Fiber Units, which are not listed, cannot
be used.

Installation Precautions
Glossy Sensing Objects
If the sensing object is glossy, detection may not be stable. If
the Sensor is inclined by 5
°
to 20
°
when using a glossy
sensing object, as shown below, detection capabilities can be
increased and stable detection achieved.
Note: Do not pull on, compress, or otherwise exert excessive force on the fiber
units after connecting them to the Amplifier Unit.
Note 1. To maintain the fiber unit properties, confirm that the lock is released
before removing the fiber units.
2. Be sure to lock or unlock the lock button within an ambient temperature
range between

°
C and 40
