SSI Transmission
Transmission
Transmission up to
400m* at 100kHz as a
function of the cable
characteristics.
Cable
High security of
transmission by using
shielded cable and
twisted pairs.
* Consult us for length > 100m.
Note: Connect DIRECTION and RAZ/RAX to a
potential (RAZ at 0V if not used)
DIMENSIONS
All Dimensions are in millimeters.
