Posital’s Hollow-Shaft kit encoders feature an open-center form factor that makes them ideal for motor, drive or robot joint installations where it is necessary for the measurement device to fit around a central shaft or centrally mounted structures, cables or pneumatic tubing. These encoders offer high precision ((18-bit electronic resolution and an accuracy of ± 0.02 degrees), plus significantly higher tolerance for dust, moisture and minor misalignment than traditional optical encoders. Based on capacitive measurement technologies, they are compact and are available with 30 and 50 mm central openings. Their multi-turn measurement range is enabled by a rotation counter and keeps an accurate count of the number of complete revolutions that the device’s rotor experiences, even when motions occur while system power is unavailable.
