Our RX100 and RX200 series products are equipped with high-sensitivity, noise-resistant second-generation Capacitive Touch Sensing Unit (CTSU) Intellectual Property (IP). The products are used in operation panels for applications ranging from home appliances to industrial equipment. The new RX600 series products, also equipped with second-generation touch IP, are scalable.
In addition, the RX100-series products are available with third-generation touch IP (CTU2L, CTUS2SL), which offers dramatically higher noise immunity – as well as water resistance – for an even wider range of applications.
