Problem
Possible cause
Countermeasure
4
The switch output does not
turn ON.
The Indicator light does not
turn ON.
Reduction in magnetic
detection force
(demagnetization)
Remove any magnetized substances such as
cutting chips or spatter from around the actuator.
Damaged cable
Replace the product.
If repeated stress such as bending stress or
tensile force is applied to the cable, take
measures to protect the product.
5
The switch output is
correct.
The Indicator light does not
turn OFF.
Product failure
Replace the Product.
6
The switch output is
correct.
The Indicator light does not
turn ON.
Product failure
Replace the Product.
7
The operation is unstable.
(chattering)
Improper setting
(mounting) position
If the product is operating near the limit of the
operating range, position the product to the
centre of the operating range.
Displacement from set
position
If the mounting bracket or mounting screws are
loose, tighten them using the appropriate
tightening torque at the correct position.
Incorrect wiring
Check and correct the wiring.
Damaged cable
Replace the product.
If repeated stress such as bending stress or
tensile force is applied to the cable, take
measures to protect the product.
Malfunction due to
magnetic field
Keep the actuator 40 mm or more away from
adjacent actuators to avoid the influence of
magnetic fields. Install a magnetic shielding plate
between the actuators.
If a magnetic field source is present near the
actuator (electric welding machine conductor,
motor, strong magnet etc.), use a magnetic
shielding plate between the magnetic field source
and the actuator.
The Sensor turns ON even
when the piston magnet is
not in the operating range.
(or the product operates at
multiple points).
