Linear Position Transducer Rides The VARAN Bus

1 of Enlarge image

Described as economical, the Micropulse AT linear position transducer exploits its VARAN Bus interface to track the location of up to four position-marker magnets. The transducer outputs a start/stop signal, which is used to calculate the position of each magnet using the transducer length and resolution. The VARAN Bus is an Ethernet-based industrial network protocol based on IEEE 802.3 100TX Standard Ethernet technology. The transducer 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. For more info, call Kelly Panko at BALLUFF INC., Florence, KY.
