SafetyBUS 100 - 120 Ω UL/CSA


As fieldbus cables for SafetyBUS systems for high flexible applications (e.g. power chains, gantry robots, pick&place units, conveyors, machine tools, automated production systems, etc.), in the field of factory automation. SafetyBUS is a safe, open fieldbus system, which is optimized for the transmission of data relating to machine safety: timing and content consistency of the data have the highest priority here.
