Further remarks

Contactless Data Transmission Channels

The contactless data transmission channels offer improved lifetime and reliability without the need for maintenance. The contactless design guarantees error free data transmission even at very high rotating speeds. The IRT version supports Profinet class C and other real time protocols.
The data transmission channels are realized by rotating capacitive couplers. Two channels can be provided per unit.
Measured @ 1 Gbit/s with 64 byte frames at 99% channel utilization and 800 s measurement time (for 1000BASE-T)
Measured @ 100 Mbit/s with 64 byte frames at 99% channel utilization and 8000 s measurement time (for 100BASE-TX)
Corresponds to BER ≤ 1 x 10⁻¹²
