EL5042 | 2-channel BiSS C interface

The 2-channel BiSS C interface for direct connection of BiSS C encoders is suitable for exact and fast positioning applications – ensuring high synchronicity with other processes through distributed clocks. Via unidirectional BiSS C communication, the EL5042 sends as a master the clock signal for position detection to the BiSS C slave (encoder), which returns the position data with up to 64-bit resolution. The EL5042 can be optimally adapted to different encoder types by selecting appropriate operation modes, transmission frequencies and frame widths.
