Pin Name Specification
1 MT+ Motor temperature sensor, normally closed contact, PTC,
NTC, KTY
9 U_SENS+ Sensor cables for the encoder supply.
In case of long cables, connect to US/GND at the motor
end.

resolution incremental encoder
5 #COS_Z1 / D-
13 SIN_Z1 / C+ SINE commutation signal (differential) of the high-
resolution incremental encoder
6 #SIN_Z1 / C-
14 COS_Z0 / B+ COSINE track signal (differential) of the high-resolution
incremental encoder
7 #COS_Z0 / B-
15 SIN_Z0 / A+ SINE track signal (differential) of the high-resolution
incremental encoder
8 #SIN_Z0 / A-
Avoiding EMC interferences
The outer cable shield must be connected to the housing of the angle encoder connector
with the greatest possible surface area (with low impedance).
