MSA 352 SERIES - TECHNICAL DATA
Features:
Optional: the MSA 352 is available with
air inlets on extrusion ends.
In addition to the two sets of sealing lips,
low pressure air helps to keep out
coolants and contamination.
The RSF air pressure unit DA 400
is designed to clean and regulate the encoder air.
Max. measuring length: 3040 mm
Rigid mounting; large cross-section
Mounting holes on the extrusion ends
Reference marks
Additional mounting support for longer measuring lengths
MSA 352 is equipped with an additional set
of sealing lips; the other features are identical
with MSA 350
