and an optical fibre receiver. • Insensitivity to electromagnetic interferences and
The optical fibre transmitter converts the electrical to leakage effects between lines routed parallel
signals of an encoder into optical fibre signals. • Significantly higher transmission speeds Product overview
A simple glass fibre allows reliable transmission up
to distances of 2000 m. • The optical fibre cable can be routed through Basics
explosive atmospheres
The receiver module converts the optical signals
back into electrical signals. • Cost and weight savings thanks to reduced
cabling work, especially for important cable
The modules are available in various level and lengths
power supply voltage variants.
Mounting of optical fibre modules The optical fibre modules can be mounted directly on
a TS35 DIN rail (top-hat rail) according to EN 50022.
The installation width for every module is only 19 mm.
Laying and connection Laying the cable is generally easy. When connecting the cable, make sure that the
