POSITAL’s family of hollow shaft absolute rotary encoders are perfect for servomotors, stepper motors, robot joints and anywhere else a hollow center design is needed to achieve an optimal mechanical layout. Both single and multi-turn variants are available. A self-powered rotation counter for multiturn models employs POSITAL’s Wiegand energy-harvesting technology – eliminating the need for backup batteries and lowering maintenance costs!
This line of kit encoders offers excellent accuracy (+/- 0.02°) and dynamic response (up to 6000 RPM), making them suitable for use in critical motion control systems. However, an advantageous problem-solver in many applications is their package design. Both stator and rotor elements are in the form of disks with large central openings. This makes them an ideal choice in space-limited situations, such as servomotors, stepper motors or the joints in robotic arms , where it is desirable to have an embedded position sensor fitting around a central shaft or axle.
