1 Introduction / Supplied items
SENC 150
The SENC 150 precision glass scale linear encoder provides the
accuracy and reliability of an ACU-RITE
®
measuring system with
digital output. Features and options include:
Resolutions of 0.5, 1, or 5 µm.
Accuracy grades of ± 3, and ± 5 µm/1000 mm.
Vinyl or armor cables of 5, 13, and 19 ft. length.
Distance-coded reference marks.
Note: Mounting and commissioning is to be conducted
by a qualified specialist under compliance with local safety
regulations. Do not engage or disengage any connections
while under power. The system must be disconnected from
power.

Locate the scale case so underside of end caps are flush
with the axis parting line.
Mark one end mounting hole location.
Alignment brackets must not be removed until instructed.
