SMAG + MTAG SSI
The output code is GRAY.
The measuring step is equal to the resolution (0.1 mm … 0.005 mm).
Structure of the transmitted position value:
SMAG-GA-100-... bits 25 … 14 13 ... 1
SMAG-GA-50-... bits 25 … 15 14 ... 1
SMAG-GA-10-... bits 25 … 17 16 ... 1
SMAG-GA-5-... bits 25 … 18 17 ... 1
value 00 … 00 MSB … LSB
* When the profile is 650 mm / 25.59” long

WARNING
Please note that the position value issued by the sensor is expressed in pulses;
thus you have then to convert the number of pulses into a linear measuring
unit.
To convert the position value into millimetres (mm) or micrometres (µm) you
have to multiply the pulses by the linear resolution of the encoder expressed in
millimetres or micrometres.
EXAMPLE 1
SMAG-GA-50-…
resolution = 50 µm = 0.05 mm
detected pulses = 123
position value = 123 * 50 = 6150 µm = 6.15 mm
EXAMPLE 2
SMAG-GA-10-…
resolution = 10 µm = 0.01 mm
detected pulses = 1569
position value = 1569 * 10 = 15690 µm = 15.69 mm
