Absolute linear magnetic encoder system
Electrical connection
The electrical connection is made via an FFC cable, which
is contacted on the sensor module via a ZIF connector of
type FH34SRJ-12S-0.5SH.
The connection or pin assignments for the respective
version can be found in the following table.
If the sensor is supplied with voltage that is
isolated from the processing electronics, the
GND for this voltage must be connected to the
GND of the processing electronics.

1) Unassigned leads must not be connected.
2) The meaning of the signals (sin, cos, A, B) varies with the controller manufacturer. Compare the controller documentation and wire accordingly.
3) Signal is given a * by some controllers.

The sensor module must be externally
connected via a limited-energy circuit as defined
in UL 61010-1, a low-power source as defined
in UL 60950-1 or a class 2 power supply as
defined in UL 1310 or UL 1585. All signals
connected to the sensor module must be in a
circuit according to LEC, Class 2 or LPS.
