5.3.2 Function and application

The product is a non-contact analog position sensor. The sensor provides an out-
put signal proportional to the cylinder stroke.
The magnet integrated in the cylinder piston generates a magnetic field. This
magnetic field acts on the sensor elements that are arranged along the longitudi-
nal axis of the distance measuring sensor. A special evaluation of the sensor sig-
nals determines the current position of the cylinder piston. For further informa-
tion, see the Technical Information (MNR R412018764).
The measurement range is set to the entire measuring length of the respective
sensor at the factory. The zero point and final value of the measurement range
can be adjusted to the stroke to be measured via a teach-in button. The product

can be used specifically for measuring a section of the entire cylinder stroke (par-
tial stroke sensor).
If the magnetic piston leaves the sensor's measurement range, the output signal
is frozen at the most recently measured value until the magnetic piston again en-
ters the measurement range.
As analog output, a voltage and current signal is made available (see g Table 2
and g Table 3).
An in-range display supports assembly of the distance measuring sensor: An LED
lights up when the magnetic piston is within the measurement range.

6 Assembly and installation

5,8
Before you start with the installation: Familiarize yourself with the basic specifica-
tions for assembly as early as possible in advance: see sections g 6.1. Planning
and g 6.2. Preparation.

6.1 Planning

In the following, you will read which basic requirements must be met so that you
can successfully and safely assemble the product.
Do not carry out the preparation and installation steps until you have successfully
completed the planning.

6.1.1 Basic requirements

The following specifications apply to the assembly of all products.
Installation-specific requirements
• Observe the set-up regulations in the country of use.
• Assembly only by qualified personnel (see section g 2.5. Personnel qualifica-
tions).
Ambient conditions
• Only use the product in non-aggressive industrial atmospheres (explosion
protection). Only then can explosion protection be guaranteed.
• Comply with the limits (accident prevention, material protection). Limits: see
section g 13. Technical data.
• If the ambient air contains aggressive substances: Get in touch with our con-
tact address to determine whether use of the product is still possible (contact
data: see back cover).
• Let the product acclimatize for a few hours before installation. Otherwise wa-
ter may condense in the housing.
Accessibility
Install the product in the system part so that the following connections and oper-
ating parts are always accessible or have enough room:
• Electrical connections
• Pneumatic connections
• Cable and tubing

6.1.2 Notes on safety

To eliminate risks during assembly, observe the notes on safety: see section
g 2.6.1. Notes on safety.

6.1.3 Installation conditions

The installation conditions include the specifications that apply specifically to the
product family that your product belongs to.
General requirements
• Make sure that the product is installed in a manner that protects it from all
types of mechanical loads.
• Install the product in an area protected from UV radiation.
Product-specific requirements
• Mounting orientation: see section g 13. Technical data.
• Use a power source in compliance with IEC/DIN EN 60204-1.
• Avoid ferritic components in the immediate vicinity of the product.
Strong external magnetic fields (e.g. welding devices) or ferromagnetic add-
on parts located in the area of the proximity switch could possibly impair the
product function.
