Innovative Multiturn Kit Encoders

Innovation in Motor Feedback


Cost-Efficient Multiturn Kit Encoders

POSITAL’s new family of kit encoders provide the manufacturers of servomotors and other machinery with a rugged, accurate and cost-efficient means of building rotary position measurements into their products. The new kit encoders are based on POSITAL’s highly successful self-contained magnetic rotary encoders. Now however, the core components of these instruments are available as separate assemblies that can be readily integrated into other products.

  • Electrical Resolution: 17 Bit Singleturn, Up to 32 Bit Multiturn
  • BISS C, SSI, RS485-Based Protocols
  • Robust & Easy to Install
  • Insensitive to Dust and Moisture
  • Compact & Cost Efficient
  • Based on Wiegand Energy Harvesting System

Alternative to Resolvers and Traditional Optical Systems

The POSITAL kit encoder components offer a number of advantages over the rotation measuring devices that have traditionally been used with servomotors and rotating equipment. Compared to resolvers, they are more accurate and offer multiturn measurement capabilities. They also provide digital outputs instead of the analog signals produced by resolvers. While POSITAL’s magnetic encoder technology provides lower precision than the best optical disk encoders, it is less costly, less vulnerable to contamination from oil or dust and more resistant to shock and vibration. POSITAL encoders also provide an all-electronic multiturn absolute position measuring capability that evaluates the full absolute angular position, including the total number of shaft rotations.

  • Compact Solution: No Coupling or Bearings
  • Insensitive to Dust and Moisture
  • Accurate Motor Feedback

Specifications of Kit Encoders

POSITAL magnetic kit encoders are easy to incorporate into normal manufacturing processes since they don’t require extra-precision, near-cleanroom assembly conditions. A built-in self-calibration capability can compensate for small sensor-to-shaft alignment errors. For servomotors with magnetic brakes, a special magnetic shield has been developed to isolate the magnetic pickups of the measurement system from the external magnetic fields.

  • Electrical Resolution: Up to 17 Bit, Multiturn: Up to 32 Bit
  • BISS C, SSI, RS485-Based Protocols
  • Accuracy: 0.1⁰
  • Operating Temperature: -40 to +105 ⁰C

The electronic components, including Hall-effect sensors, a 32-bit microprocessor and the Wiegand-wire energy harvesting system, are packaged in a convenient 36mm diameter, 24.2mm deep unit.

Versatile Digital Displays

POSITAL Versatile Displays

On-site Position or Speed Measurement

POSITAL has added a series of stand-alone digital display units to its catalog of accessories. The new units are designed to connect directly to POSITAL’s IXARC rotary encoders, TILTIX inclinometers, LINARIX linear sensors and provide a direct readout of position, rotational speed or angular displacement.

  • Connect to Encoders, Inclinometers or Linear Sensors
  • Analog, SSI or Incremental Input
  • Digital or Analog Output
  • Easy Integration to more Complex Control Systems
Depending on the type of sensor, the display units can be ordered with Analog, SSI or incremental inputs. Built-in output conversion (D/A or A/D) is also available, with up to four digital and one analog output channels. This makes these units very versatile. Teaming up a digital display with an encoder inclinometer or linear sensor provides a simple, convenient and accurate measurement tool for on-site position or speed measurement. The output channels make it easy to integrate the sensor and display into more complex control systems. And, thanks to their compact size and sturdy construction, these displays can be located close to the machinery where the encoder is mounted so that they can be used for machine setup tasks or as a cost-effective way of monitoring machine status on the factory floor.


Regardless of input type, these displays can be programmed to display angular position, linear position or rotational speed directly and to provide limit warnings or cam-follower functionality. Programming can be done through front-panel buttons or with an easy-to-use PC-based programming tool.
