OMRON R88A-FIW4006-E-UL Noise Filter for 400V Servo Drives

The OMRON R88A-FIW4006-E-UL (R88A-FIW4006-E-UL) is an industrial EMC noise filter engineered for use with 400 V servo drive systems. Designed to suppress high-frequency electromagnetic interference and conduct noise mitigation along power supply lines, this noise filter ensures electromagnetic compatibility across automated machinery and servo-driven equipment. Rated for a nominal voltage of 400 V AC and a rated continuous current of 6 A, the unit carries UL certification, meeting international safety and electrical compliance standards. It effectively reduces electrical line noise generated by pulse-width modulation inverter switching within servo amplifiers, protecting sensitive control circuitry and maintaining stable communications across industrial networks. The OMRON R88A-FIW4006-E-UL noise filter is suitable for cabinet installations in motion control systems, multi-axis robotics, CNC machines, and packaging equipment that operate on 400 V power distribution networks.
