Owing to our domain expertise and rich industry experience, we have been able to design and manufacture a broad range of Balluff Micropulse Linear Transducers. Under the strict vigil of our professionals, these transducers are developed at our state-of-the-art manufacturing facility using optimum-grade material and sophisticated techniques. Prior to their dispatch, these products are rigorously inspected on certain parameters of quality so as to ensure their defect-free nature.
Canopen: The position of the magnet along the waveguide is sent over the CANbus to the controller in so called Process Data Objects or PDOs. Micropulse transducers work with standard CANopen protocols as per CIA DS 301 and with the standard device profile as per DS5406. CANopen offers greater flexibility because of the large number of configurations options for the transducer. For example, the resolution is programmable for 5, 10, 20 or 100 µm – depending on your application. Alternatively you can select whether both position and velocity information are sent to your controller, cyclically or on-demand. And there’s more: Up to 4 so-called software cams can be defined in the active measuring range. Each time the status of one of these cams changes, high-priority emergency messages are sent to the controller.
Profibus: The Process Data Unit sends position and velocity information for the transducer to the controller via the PROFIBUS-DP. Micropulse transducers operate according to EN 50170 and support the PROFIBUS-DP encoder profile as well as mufti-magnet operation. Micropulse transducers can be parametrized using the GSD file. The position resolution can be configured in 5 µm increments and the velocity resolution in increments of 0.1 mm/s. Working ranges and the null point can be configured individually for each magnet.
Pulse interface; The time between an interrogation and the reply signal is directly proportional to the position of the magnet along the waveguide. These pulses are transmitted using RS485/422 differential line drivers, guaranteeing noise-free signal transmission over distances of up to 500 m. The great advantage of these interfaces is the noise-immune signal transmission with a simple and economical interface. Interfaces with Trista outputs allow multiplexing of several Micropulse transducers. Appropriate control cards are available.
Quadrature: The quadrature output interfaces directly to standard encoder inputs (90° out of phase, A & B). This configuration gives you more interface options for connecting to motion based systems. In addition, the Micropulse quadrature output transducer has the ability to provide absolute position information through use of its innovative BURST function.
