US Digital announces the release of its latest absolute, blind hollow bore shaft encoder, the HBA4. HBA4 absolute encoders are used as azimuth and elevation position sensors in two axes tracking systems, commonly used in solar applications.

This single turn absolute encoder provides 16-bits of resolution over 360 degrees of shaft rotation. The HBA4 is available with a 12mm or 0.500” diameter bore size with either a ball bearing or sleeve bushing bearing assembly and is sealed to an IP66 rating.

The absolute encoder 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.
