Mounting Information
SENC 50
This linear encoder with small cross
section is fastened at points on a machined
surface. With a back-up spar, only two
points, one at each end, are suffi cient.
For mounting without back-up spar, an
intermediate support is required in addition.
The encoder is mounted so that the sealing
lips are directed downward or away from
splashwater.
Mounting
When mounting, the scale unit must be
aligned at several points along the machine
guideway. Stop surfaces or stop pins can
also be used to align the scale.
The proper gap between the scale housing
and scanning unit is ensured by the
shipping brace. You must also ensure that
the lateral tolerance is maintained.
Accessory
Back-up spar for SENC 50
ID 680 803-xx
The SENC 50 can be mounted on a back-up
spar to increase stability.
SENC 150
The SENC 150 is fastened at its ends by
their mounting blocks to a machined
surface. A support bracket is provided for
measuring lengths above 625 mm.
If the SENC 150 is mounted with a back-up
spar, there is no need for the support
bracket. At measuring lengths of 1675 mm
or more, the back-up spar is essential. The
encoder is mounted so that the sealing lips
are directed downward or away from
splashwater.
Mounting
When the SENC 150 is mounted, the
shipping brace already ensures the proper
gap between the scale unit and the
scanning unit. You need only align the scale
unit at several points along the machine
guideway.
Accessory
Back-up spar for SENC 150
ID 680 116-xx
The SENC 150 can be mounted on a back-
up spar to increase stability. At measuring
lengths of 1675 mm or more, the back-up
spar is essential and is already included in
delivery.
