Wiring requirements greatly reduced
A MIL connector allows for easy snap connection
of the gang-mounted sensor output to a PLC or PCB
controller. And since there is no need for separate
power and signal cables for each sensor, the wiring
required at installation is greatly reduced. |

Remote |
![]() Solution:
Dispersed remot installation simplifies equipment
design |
| • |
Master unit positioned for easy operation |
| With a dispersed remote installation,
you can position the master unit within easy
reach of the operator. With this arrangement,
configuration is easy no matter where the
sensor units are installed. And wiring is
neat, thanks to the use of MIL connectors. |

| • |
Sensor units positioned close to the
point of detection |
| With a dispersed remote installation,
you can position the sensor units exactly
where they are needed; you need only think
about where the fiber-optic cable goes. And
when in place, you can connect the sensors
to the master unit by linking remote units
with one-touch ease. |
|
 |
|
| |
| • Remote units |
| The dispersed sensor units are mounted together
with a remote unit that is daisy-chained via another
remote unit to a single master unit. The remote
units are linked via reliable MIL connectors that
are easy to attach and detach on-site. |

| 5 Tuning Modes |
![]() Set
Mode (Tuning) |
| |
 |
|
 |
|
 |
2-step
This reliably detects differences as minute as the
thickness of a sheet of paper. |
|
Position
This mode is used to detect a target position with
high precision. |
|
Max. sensitivity
Maximum sensitivity tuning is used if through-scan
or diffuse-scan optical fibers are used without
reflective backgrounds. |
 |
|
 |
|
|
BGS
With BGS or background suppression tuning, the background
is memorized so that any target passing in front
of it can be detected. |
|
Full-auto
Full-auto mode allows tuning without having to stop
the line. The operator just presses the dial switch
once and the rest is accomplished automatically.
(OP level is adjusted so that the light level falls
between max. and min. limits) |
|
|
|
|
| Easy Operation |
Just look at the mode indicator
and turn the dial
The configuration procedure is completely intuitive.
With the combination of jog-dial switches and mode
indicator, there is no need to refer to a manual.
Operation is "sophisticated yet simple": all it
requires is one finger. |
|
 |
|
|
| High Resolution |
| Depending on the light level
during tuning, the HPX-ET automatically selects
the optimum amp gain (sensitivity) from among 5
levels. At minimum sensitivity resolution is as
much as 625 times what it is at maximum sensitivity
- a figure that cannot be approached by any other
photoelectric sensor on the market. |
|
 |
|
|
| Clear Indicators |
| The HPX-ET employs relative level
indication. This avoids the problem encountered
with conventional equipment using absolute level
indication, in which figures change when switching
applications and which do not even guarantee uniformity
for the same application. |
The level of light received during operation is
displayed on a relative scale from -100 to +100.
Compared with absolute level indication, which changes
with each application, this relative level indication
is consistent whatever the application. |
|
 |
| • |
Contrast margin
indication |
This displays the contrast margin from 1 to 100
following tuning. |

|
| Space-saving
Design |
| • |
Narrow spaces no
problem |
With this design there is no need for each sensor
to have its own power and signal cables. The space
required is thus greatly reduced and units can be
installed in places too small for conventional equipment. |
|
 |
|
|
| OP &
Timer Adjustment |
| • |
ADJ (OP level adjustment)
mode |
In ADJ mode, the OP (operating point) level can
be freely adjusted within the -100 to +100 range.
This is a great convenience when actual conditions
differ from tuning conditions, since it saves the
operator from having to retune a sensor on-site. |
|
 |
| • |
DLY (delay timer
setting) mode |
In this mode, the delay timer can be switched either
ON or OFF. The delay itself can be set from 1 to
99 msec (in 1 msec increments) or 100 msec to 1
sec (in 100 msec increments). |
|
 |
|
|
| Slide Connector |
|
Thanks to the special slide connector, even when
gang-mounted each sensor unit can be replaced quickly
and easily. (Previously, replacement involved sliding
the sensors along a DIN rail). |
|
 |
|
|
| Mutual
Interference Protection |
| • |
Controlled
pulse-shift emission |
Thanks to controlled pulse-shift emission technology
(patent pending), up to 4 optical fibers can be
installed side by side without suffering any interference. |
