CUI Devices AMT22 Modular Absolute Encoders

CUI Devices AMT22 Modular Absolute Encoders output 12- or 14-bit absolute position information with full-duplex serial peripheral interface (SPI) communication and include single-turn or multi-turn output options. These encoders feature a 2MHz date rate and a compact modular package with a locking hub for easy installation. A capacitive platform ensures that these high-accuracy encoders offer protection from dirt, dust, and oil. CUI Devices AMT22 Modular Absolute Encoders are ideal for industrial automation, robotics, and renewable energy applications.
