Special: Free positionable switching magnets for special functions.
The position of the 2 switch points (S1 and S2) within the measuring length
can be select by the customer
Measuring lengths: 70 mm to 2240 mm
Measuring scale: glass scale

Position of the
Reference mark:
(selectable)

MSA 691.xx K:
Distance coded Reference marks (K): after travelling 20 mm the absolute
position will shown on the display.
MSA 691.xx:
Standard: Up to measuring length 920 mm one Reference mark in the middle
of the measuring length or 35 mm from both ends of measuring length,
