Use Regulations
Magnetostrictive displacement sensor is used to detect the displacement of motion mechanism. According to
the selection regulations, the magnet ring (block) matched with magnetostrictive displacement detection electronic
components is selected for detection applications in different occasions. Please ensure that the cable, connector,
magnet ring (block) and sensor body are the original parts of the manufacturer when using. Please do not open the
shell of the sensor without authorization, so as not to affect the normal warranty period of the product.
Saftey matters
Please read the operating manual carefully before powering up the sensor. Firstly, confirm the outgoing mode
and pin signal definition, and make correct electrical connection to prevent power-on from damaging the sensor or
causing misoperation of the equipment.
During the construction and use of the sensor, the current of high-power equipment such as welding machine
should be avoided from entering the working circuit of the sensor.
If you find abnormal sensor data or obvious changes in appearance (such as bumping deformation), please
stop using it immediately, and contact the manufacturer to confirm the current state of the sensor before continuing
to use it.
ES structure magnetostrictive displacement sensor has no LED lamp for status indication.

Application environment
Magnetostrictive displacement sensor is a kind of magnetic measurement sensor. Make sure there is no
strong magnetic field around the sensor, which may interfere with the data. The displacement output signal cable
of magnetostrictive displacement sensor should be away from the power cable or large current or strong pulse
interference source.Confirm the environmental parameters including temperature, vibration, etc., and ensure that
the working conditions are within the nominal working parameters of the sensor.
Installation
The installation of magnetostrictive displacement sensor mainly includes sensor body, magnet and cable
fixing.
The installing forms of the sensor body are: thread installing, clamp installing and matching fixing installing.
Before installation, make sure that the packaging is in good condition, and the sensor body has no obvious
bending and bumping. The sensor body should be assembled according to the specific installation form.
When installing magnets, please use matching magnetic insulation gaskets to ensure normal magnetic field
circuit.
When installing plugs or cables, please connect them accurately according to the electrical interfaces in the
instructions.
After-sales support
If the sensor malfunctions, please contact the after-sales department of the company in time. Do not attempt
to repair it yourself.
(Note: * when selecting the float, the head
non-usable area ≥ 14 + the float radius
