Signal converter and transmitter
max. 100 kHz, 850 nm | LWL
Johannes Hübner
As an alternative to conventional signal transmission using copper cables the signal from incremental encoders can also be transmitted through fiber optic cables (FOC). The signals (0°, 90°, marker pulse and LED check) available in parallel from the encoder are coded in the transmitter and transferred via just one fiber optic cable to the decoder in the switchboard. The decoder converts the coded signals back into the standard electrical signals and the inverted signals are also available.
Advantages of Huebner's fiber optic signal transmission components
High data transmission frequency for long cables
EMI immunity and thus high transmission safety
Less cabling costs by transmission via just one fiber optic cable
Electrical isolation (incremental encoder - decoder)
FOC-decoder with 2 output blocks (option: mutual electric isolation)
Output blocks optionally with HTL and/or TTL signals
Monitoring of fiber optic cable breakage to increase the system safety (optional)
