The HMT25 geared multi-turn encoder provides absolute position information over multiple turns of the input shaft. It keeps track of the exact position even during periods of power loss without the need for a battery backup. The HMT25 series is capable of outputs up to 4096 counts per turn and can count up to 4096 turns—a total of 24 bits or 16,777,216 positions. Units are enclosed in a 2.5- inch diameter sealed package to withstand rugged environments and they carry an IP 66 environmental rating. These encoders meet the long travel and high resolution requirements of robotics, rolling mills, rotary tables, cable winding, printing, converting and material handling systems.
