Heidenhain KCI 120 Dplus rotary encoder provides motor feedback and position measurement

Heidenhain has introduced the KCI 120 Dplus rotary encoder to fulfill two critical needs via a single component in high-accuracy robots. This absolute encoder provides reliable feedback to a robot’s motor and accurate position measurement to its controller to enable safe and accurate motion, the company states.

The encoder comprises one scanning head and two types of rotor units, all connectable to a controller/drive via a single cable. At 20 mm high, its small footprint and low weight make it useful in tight installation spaces, rendering it suitable for a variety of high-accuracy motion control applications.

The rigid design of the two-in-one encoder permits high vibration loads of up to 400 m/s² on the stator and 600 m/s² on the rotor. And because of its robust inductive scanning method, the encoder is resistant to contamination and magnetic fields.

It is available with Functional Safety capability and, with measures in the control, achieves an SIL 3 safety rating. This allows manufacturers to minimize malfunctions and facilitate the safe operation of associated machines and automated systems.
