Transducers with real-time Ethernet interfaces
Balluff has released transducers in rod and profile housings with an Ethernet interface which are claimed to offer help machine manufacturers and operators with respect to startup and machine output.
The standardised communication protocols and automatic address assignment are said to simplify integration of the transducer into the controller and the plant network. Because of this, a complex programming process is no longer necessary. This leads to a shortened machine startup time; low implementation costs and reduces fault sources simultaneously.
The transducer is suited for use in advanced applications, such as those involving controlled axes, due to synchronous, fast and secure real-time data transmission and its precise position measurement with 1µm resolution. This contributes to a higher machine output and improved production quality. The transducers of the BTL7 series are said to detect and process up to 16 position encoders. Two values can be output for each position encoder: the position and the speed.
Selectable real-time Ethernet interfaces include Profinet IRT, EtherCAT and Varan. The transducers are available in four designs: classic rod housing for installation in the cylinder and three profile versions for flexible mounting on a machine. The profiles include a 36 x 36mm design, a flat profile with an overall height of 21mm and a round profile 30mm in diameter.
