Balluff’s Micropulse AT linear position tranducer with VARAN Bus interface is able to track the location of up to four position-marker magnets. This transducer outputs a start/stop signal, which is used to calculate the position of each magnet using the transducer length and resolution. It is available in a non-contact, floating magnet configuration, with optional measuring ranges from 50 mm up to 1.5 m. The VARAN client chip is embedded into the transducer itself as a low-cost FPGA, allowing simple read/write configuration and making it an economical solution for linear positioning. VARAN Bus is a robust Ethernet-based industrial network protocol based on IEEE 802.3 100TX Standard Ethernet technology. It offers enhanced resistance against disruption, high data integrity, fast bus speed operating in "hard real-time", with bus cycle times less than 100 µs and low jitter below 100 ns.
