BIC Q40 inductive couplers allow contact-free data and energy transfers through a recording gap. It makes data transfers in both directions possible as well through the new bidirectional coupling system in the 40×40 unicompact housing is used with IO-Link. Its IO-Link standard is set up transparently, allowing the BIC system to work in the background and function without parametrisation via plug-and-play between master and device. the system has a complete IO-Link interface ensuring data are directly exchanged between the master and the device. It is a highly-productive system that guarantees increased machine availability and minimal downtime thanks to the wear-free and highly-reliable connection.
