HEIDENHAIN’s Innovative Dual Encoder for Robots

KCI 120 Dplus provides both motor feedback and position measurement

SCHAUMBURG, IL (September 2021) - Designed to fulfill two critical needs via a single component in high accuracy robots, HEIDENHAIN introduces the innovative KCI 120 Dplus rotary encoder. This new unique absolute encoder provides both reliable feedback to a robot's motor and accurate position measurement to its controller to enable safe and accurate motion.


Extremely compact, the KCI 120 Dplus encoder consists of one scanning head and two different types of rotor units, all connectable to a controller / drive via a single cable. Only 20 mm in height, its small footprint and low weight makes it useful in tight installation spaces, rendering it attractive for a variety of high accuracy motion control applications.

The rigid design of this new two-in-one encoder from HEIDENHAIN permits high vibration loads of up to 400 m/s² on the stator and 600 m/s² on the rotor. And thanks to its robust inductive scanning method, the KCI 120 Dplus rotary encoder is particularly resistant to contamination and magnetic fields.

The KCI 120 Dplus encoder is available with Functional Safety capability and, with measures in the control, can achieve SIL 3 safety rating. This allows manufacturers to minimize malfunctions and facilitate the safe operation of its associated machines and automated systems.
