Azimuth & elevation absolute encoder

US Digital’s latest release is the HBA4 absolute, blind hollow bore shaft encoder. HBA4 absolute encoders are used as azimuth and elevation position sensors in two axes tracking systems, commonly used in solar applications. The single turn encoder provides 16-bits of resolution over 360° of shaft rotation and is available with a 12mm or 0.500" diameter bore size, with either a ball bearing or sleeve bushing bearing assembly. The HBA4 slips over a shaft and is locked in place with a non-marring clamp mount. A flexible anti-rotation tether provides single-point mounting for bolt circles ranging from 2.50" up to 5.00" in diameter and compensates for shaft run out. The HBA4 communicates serially to a host via the industry standard RS485 bus and is sealed to an IP66 rating.
