LD120-M7
SM5
Description
This manual describes the LD120 display and the
sensors of the SM5 series. The purpose of this
system is to display displacements on industrial
machines
and
automation
measurement system includes a LED display,
magnetic tape and a magnetic sensor. As the sensor
is moved along the magnetic tape, it detects the
displacement which is shown on the display. The
flexibility of the tape allows it to be used for both
linear and angular applications.

1 - Safety summary
We strongly recommend carefully reading this user
manual and following the installation guidelines:
• Measurement system (sensor) should be installed
as close as possible to the display.
• Always use shielded and twisted cables if
possible.
• Avoid running the sensor cable near high
voltage power cables (e.g. drive cables).
• Install EMC filters on sensor power supply if
needed.

• Avoid mounting sensor near capacitive or
inductive noise sources such as relays, motors,
and switching power supplies.
Connect according to the chapter 5: "Electrical
connections".
2 - Identification
The display and sensor can be identified by the
label's data (ordering code, serial number). This
information is listed in the delivery document. For
technical features of the product to make reference
at the technical catalogue.
3 - Installation
Install the product according to the protection level
provided. Protect the system against knocks,
friction, solvents, and respect the environmental
characteristics of the device.
4 - Mounting steps
4.1 Display
Push the display into the cut-out (approx. 68 x 33
mm
2
) without panel clips.
Install panel clips on the display's housing and screw
until fixed.
4.2 Magnetic tape
See manual supply with the magnetic tape.
4.3 Sensor mounting
4.3.1 Sensor type SM5-R (rectangular)
Sensor can be fixed by means of two M3 screws
over the buttonholes. Make sure that the gap
between sensor and tape is in respect with (fig. 1)
along the total measuring length. Avoid contact
between the parts. You can check planarity and
parallelism between sensor and magnetic tape using
a feeler gauge.
