With its small dimensions and high reliability, the KCI/KBI 1300 series of inductive rotary encoders are made specifically to support compact servomotors for collaborative and service robots.
Each lightweight KCI 1319 / KBI 1335 encoder includes a 25 mm hollow shaft and inductive scanning technology that makes it insensitive to contamination and magnetic fields. The encoder communicates using the high-speed EnDat 2.2 interface which also allows for additional information, such as temperature or diagnostics, to be communicated as well.
In structure, these rotary encoder kits consist of a scanning unit and a rotor. The rotary encoder can be offered in two different versions: one variant consists of a graduated disk that is directly screwed onto the mating shaft; the other variant is a disk/hub assembly that is press-fit onto the mating shaft.
The rotar unit is screw-fastened or press-fitted for direct coupling. This rigid design permits high vibrational loads of up to 400 m/s² on the stator and 600 m/s² on the rotor. The inductive scanning method is also resistant to contamination and magnetic fields.
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 systems.
For a wide variety of applications, this series offers the right encoder, including a multiturn version with a battery-buffered revolution counter for up to 65,536 revolutions or a version with external temperature sensor support. The rotary encoders of this series feature high ruggedness and reliability in a compact design and their small footprint makes them ideal for tight installation spaces.
