10. CAN 100 / LIN 100 Sensors
10.1. Mechanical Design
The CAN 100 and LIN 100 sensors are pluggable and have a GND, a supply and a CAN or LIN
connection. The optical connection is designed for a 2.2 mm double plastic optical fiber (pluggable)
(Figure 9 and Figure 10).

10.2. Optical Connection
The double fiber optic cable is simply plugged into the CAN 100 / LIN 100.
At both ends, the two individual optical fibers are cut to different lengths and thus assigned to the
correct opening on the CAN 100: The slightly longer optical fiber is always connected to the optical
input (long arrow), the slightly shorter one to the optical output (short arrow) (Figure 11). The
longer optical waveguide must also be pushed further into the CAN 100 (up to the stop), so that
when correctly connected, the double optical waveguide is just connected to the
CAN 100 / LIN 100.
The maximum length of the optical fiber is 20 m.

Attention with CAN 100 and 1 MHz transmission rate:
At a transmission rate of 1 Mbit/s, however, the delay of the optical receivers limits the possible
However, the delay of the optical receivers limits the possible length (depending on the edge
steepness and response time of the other connected CAN nodes) to less than 20 m.
If the CAN 100 is only used to "listen in" on an existing CAN connection between other nodes,
there is no such limitation.
