Guiding data and media in the tightest of spaces at high speeds is a major challenge for many users, for example in intralogistics. With the micro flizz, igus offers a compact energy supply system for travels up to 100 metres. It consists of an energy chain, flexible chainflex cables for tight bend radii and an aluminium guide channel. The micro flizz can now also be used with the new smart CF.D system. This monitors the data transmission characteristics of the cable in advance and promptly warns of a failure.
