Sensor, amplifier, indicator section
Use only a DC safety power supply. Avoid connect-
ing devices, such as motor or valves, that generate
noise in power for this unit.
When wiring, do not lay the power wire for the mo-
tor, etc., in the same pipe or use the same wiring
(multi-conductor cable, etc.) because induction noise
may be applied to the length measuring sensor.
Check the inverter power supply and wiring section.
(Check that the inverter power frame ground is cor-
rectly grounded and noise is released.)
Note that noise resistance performance may be ad-
versely affected if the length of the sensor cable or
output stage cable lead is changed.
CAUTION
An elastic lead wire is used for the sensor cable and
output stage cable. To optimize elastic performance,
check that the wire is not bent locally and that ten-
sion is not applied.
Note that compared to the middle section of the load,
elasticity drops at the outlet from the sensor case or
amplifier unit case and at the M8 connector section
because the lead is fixed. Check that repeated bend-
ing is not applied to these sections.
This product cannot be used where the ambient tem-
perature fluctuates suddenly (e.g. local air conditioning).
This product cannot be used outdoors or in an envi-
ronment containing corrosive elements.
Select switch output type when conducting rough
judgments and analog output type or display when
conducting detailed judgments, including length mea-
surement.
Design & Selection
1. COMMON
This product cannot be used in an environment
where strong magnetic fields are generated (spot
welding machine, etc.) because the sensor detec-
tion accuracy drop markedly.
Take care when the cylinder and hand approach
other cylinders with magnetic switches. As a guide,
there should be no problem if there is a distance of
50mm and over between the sensor surface and
cylinder tube surface as shown below.
CAUTION
If the sensor surface (sensor nameplate fixing face)
is enclosed by a magnetic substance such as a steel
plate, the magnetic force be disturbed, and the sen-
sor not detect a magnetic field. Take care when in-
stalling the actuator.
