LF (70/455 kHz) is the first choice for the tool identification over short ranges. Other areas of use are tool transport with conveyor systems, FTS and pallet transport systems and the assembly technology and organization of supplies.
LF data couplers from Balluff ensure the greatest possible flexibility. They securely transmit the data via two air interfaces. In doing so, they handle the contactless bridging of the two transitions instead of a fixed data transmission.
The data couplers are generally used where a double mechanical interface is indispensable, for example, with rotary tables, replaceable workpiece holder or gripper arms. This way, you are able to simplify your system design and increase system availability because of fast contacts, like in tool changing.
