IncOder™ CORE Encoders

IncOder™ CORE Encoders are robust miniature PCB-based inductive ring encoders designed for robotic joints.

IncOder™ CORE Encoders are non-contact, lightweight absolute rotary inductive encoders fully contained in a printed circuit board kit. The ergonomic hollow bore design is suited for integration into rotary actuators. The position sensor utilises a unique field-proven inductive technique, delivering highly reliable, repeatable, temperature-stable measurement performance.

The angle sensor can be installed simply by mounting the rotor and stator pair into the host assembly by means of M2 mounting holes. With modest installation tolerances, a programmable zero set point, and no calibration required, the sensor can be mounted in place for a quick, practical, and reliable setup.

Each sensor includes a passive rotor target, paired with an active stator. The stator contains all the required processing electronics in a lightweight, stacked circuit board package. The stator features a 10-way Molex PicoClasp connector for power input and data outputs. The IncOder CORE can be supplied with an axial or radial connector. IncOder CORE can be configured to output up to 20 bits of absolute position data in a range of protocol options including SPI, BiSS-C, and SSI.
