2 Safety information
2.1 General notes
Should humans be at risk, or operating equipment potentially be damaged in the event
of a malfunction or failure of the device, this must be prevented by means of suitable
protective devices, e. g., emergency shutdown systems.
If the device is not functioning correctly, it must be taken out of operation and secured
against unauthorized operation.
To guarantee proper operation of the device, please observe the following:
•Protect the device against mechanical stress during installation
•Do not open the device
•Connect the device with the correct polarity, supply voltage and control pulses
•Observe the permissible operating and ambient conditions for the device
•Regularly check the device for correct operation and document the results
2.2 Intended use
2.2.1 Purpose of the device
The MAX® linear encoder is designed for position measurements in mobile hydraulic
applications (e.g. in hydraulic cylinders) and can be used to control the hydraulic com‐
ponents of self-driving mobile machines. The rugged housing offers optimum protection
against dust, climatic influences, vibrations, surrounding media, as well as electrical
and magnetic fields.
The device is a component and must be connected to a suitable electronic control unit.
The MAX® linear encoder fulfills the requirements of the following EMC standards:
MAX30N:
•EN ISO 14982:2009 and EN ISO 13766-1:2018
MAX48N/MAX48A/MAXH1A/F1A:
•EN ISO 14982: 2009 / EN 13309: 2010 / EN ISO 13766-1:2018
•EN 61000-6-2: 2005 / EN 61000-6-3: 2011
2.3 Responsibility of user
Designated users
see "Target audience", page 6.
Correct project planning
•This document assumes that appropriate project planning has been carried out
before delivery of the device (e.g., based on the SICK application questionnaire),
and the device is in the required delivery state based on that planning (see
supplied system documentation).
bIf you are not certain whether the device corresponds to the state defined
during project planning or in the supplied system documentation, please
contact SICK Customer Service.
Special local conditions
In addition to the instructions in this Technical Information, follow all local laws, techni‐
cal rules and company-internal operating directives applicable at the respective device
installation location.
