Safety Notes
These photoelectric sensors may not be used in
applications where personal safety depends on
proper function of the devices (not designed as
a safety component according to EU Machine
Directive). Before commissioning, carefully read
the user’s guide.
Caution!
Glare and eye irritation from optical beam.
Do not look into the emitter!
The CE Mark verifies that our products meet the
requirements of the current EMC Directive.
In our EMC laboratory, which is accredited by DATech for
testing electromagnetic compatibility, evidence has been
provided that the Balluff products satisfy the EMC
requirements of IEC 60947-5-2.
