POSITAL upgrades its IXARC series with TMR sensors and energy-efficient embedded microcontrollers.
POSITAL announced an upgrade to its IXARC series of incremental rotary encoders. The line now makes use of a TMR (tunnel magneto-resistance) sensing technology in place of the Hall-effect sensors used on previous models. According to the company, TMR sensors offer higher magnetic sensitivity and are less temperature sensitive and more energy-efficient. The TMR sensors will also be connected to next generation microcontrollers that offer a 60% energy consumption improvement, the company says, over older components and can support new signal processing algorithms. POSITAL says the upgraded line remains mechanically and electrically compatible with earlier models, but reduces power consumption.
