Robust design

Thanks to their robust inductive scanning method, the KCI 120 Dplus rotary encoders are particularly resistant to contamination and magnetic fields. Their rigid design permits high vibration loads of up to 400 m/s² on the stator and 600 m/s² on the rotor.

2D position measurement

KCI 120 Dplus series rotary encoders permit wide mounting tolerances of ±0.3 mm for Encoder A and ±0.5 mm for Encoder B. The circular scales are simply press-fitted onto the motor shaft and output shaft, thus permitting fast and easy installation.

Functional safety

The rotary encoders of this series are available with functional safety and a functionally safe mechanical connection. Once integrated into an application with up to SIL 3 safety, they minimize malfunctions and facilitate the safe operation of machines and automated systems.

Compact design

The KCI 120 Dplus unites two rotary encoders in a single device, offering high reliability in a rugged and extremely compact design. Thanks to its low 20 mm profile, this series is great for tight installation spaces.
