rotary encoders for robotics
KCI 120 Dplus
The KCI 120 Dplus dual encoder delivers motor feedback and position measurement in a single module that is resistant to ambient conditions and aging.
Two rotary encoders in one device
The new KCI 120 Dplus dual encoder from HEIDENHAIN delivers motor feedback and position measurement in just one rotary encoder. By measuring the position downstream from the gearbox, the KCI 120 Dplus compensates for inaccuracies inherent in highly mobile and dynamic robots. This is necessary because, in order to achieve the desired mobility, articulated robots, operate with serial kinematics and up to six axes. Each of them influences the accuracy:
- Each axis is driven by a servomotor via a gearbox that exhibits zero-position error, reversal error, and joint elasticity
- In addition, forces and dynamic effects of the machining process impair the positioning accuracy
In order to perform its dual functions, the KCI 120 Dplus encoder has one central scanning unit and two separate circular scales. It is thus very compact and easy to integrate. The purely serial EnDat 2.2 interface with functional safety permits its use in safety-related applications such as human-robot collaboration.
Robust and reliable
The KCI 120 Dplus rotary encoders are dependable, robust, and compact. These remarkable solutions are resistant to contamination and magnetic fields. Functional safety and a safe mechanical connection are available.
Compact and accurate
The KCI 120 Dplus rotary encoders feature a flat profile and wide mounting tolerances. Dependable installation is easy to automate: the two circular scales are simply press-fitted onto the motor shaft and output shaft.
