Alterix Ltd

Alterix, based in Cambridge, UK is a developer of high precision rotary encoders. Our technology allows relaxed mounting tolerances and therefore greatly simplifies sensor installation in mechatronic systems. Alterix plans to establish partnerships in new markets for encoders integrated into robotic joints in articulated robotic arms. Standard hollow encoder installation requires precision mechanics and skills. Our low-cost modular encoders can be installed by unskilled labour, requiring less time for assembly while achieving higher yields. Our sensors are prepared for field testing, and we are ready to work with manufacturers in Asia to achieve the ideal form factor for their products.

Robot Joint Angular Sensor: Best Performance, Low Price

Developers of mechatronic systems are aware that potential quality of the output is only as good as the quality of the encoders integrated into it.

Does your product require high-precision angular control? Is it tedious to achieve micron-precise alignment of your disk targets to reduce a significant sinusoidal angular error? There is a solution that frees your resources for other priorities! Novel technology solution for high-precision kit encoders provides installation time and cost saving. New encoders can be easily mounted by inexperienced technicians.

These smart self-calibrating inductive sensors are designed to operate even with large axial misalignments. Developed within Cambridge technology consultancy cluster, the bearingless sensors are more economical and accurate than the best optical encoders.

After switching the power supply on and off, the output of encoders remains the same. Such sensors can therefore be used to control movements of machine parts with uncompromising precision.

Inductive encoders consist of two circuit boards, each with a set of printed coils. One PCB is attached to the rotating shaft. The symmetrical design of the coils and circumferential scanning makes the sensor insensitive to small misalignments between the axis of rotation and the centers of the coils. The axial misalignment tolerance of 200 microns is significantly improved over the one micron that optical and magnetic encoders are subject to.

The technology owner is looking for collaboration with industrial partners for modifying geometry of the sensors to fit specific mechatronic systems including application in robotic joints of collaborative (“cobot”) and service robots.
