General precautions ..................................P.986~□
High-speed detection even a little liquid leak
Reliable detection
The unique eect of
capillarity enables reliable
detection of small leaks
and viscous liquids.
EX-F70 SERIES
No need for sensitivity adjustment
No need for sensitivity adjustment with adjuster, so initial
mounting is easy.
Easy operation check
Safe design
If the sensor is not mounted correctly, if the cable is cut or
disconnected, or if the sensor is not operating correctly, the
output is the same as when the beam is not received (LEAK).
Design deals with human errors such as, forgetting to
mount, etc.
This sensor is equipped with a NORMAL indicator (green)
which lights up when mounting correctly, and a FAULT
indicator (red) which lights up when sensing the leaked liquid
or when mounted incorrectly (forgetting to mount exclusive
mounting bracket). So, the operation can be checked easily.
PVC mounting bracket available
A mounting bracket made of PVC (polyvinyl chloride) is
available. This type of mounting bracket can be utilized
without problems within environments that would corrode
normal metal brackets.
Easy installation & reset
Facilitates easy installation: the SUS mounting bracket
type can be installed using only a single screw and the
PVC mounting bracket type can be installed using only
two screws or an adhesive. No component replacement
required for resetting after leak detection. The simple
shape makes it easy to wipe o the leaked liquid.
Capillarity eect
New type of detection method
When a leak occurs, the beam from the beam-emitting part scatters
through the leaked liquid and is not transmitted to the beam-receiving part.

The beam from the beam-emitting part
scatters through the leaked liquid and is
not transmitted to the beam-receiving part.
The beam from the beam-emitting part
reflects off of the surface of the sensor and
is transmitted to the beam-receiving part.
Compact, space-saving
This slim (10 mm 0.394 in)
side-mounting sensor is
especially good for use
in conned spaces.
