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
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.
Reliable Pitch ControlIXARC magnetic absolute encoders are used to precisely determine blade angles for the pitch control system. A high level of environmental protection is a key requirement here, since extreme conditions prevail especially in offshore wind turbine parks. With durable, salt-spray resistant IP69K housings and a shaft load capacity of up to 300 N, POSITAL absolute encoders are ideal for these tough conditions. Based on an innovative magnetic technology that does away with the need for gears or batteries, the encoders are very compact and easy to install in limited spaces.
Resolution up to 30 bit (16 bit per Revolution)
Durable in Harsh Environments
Compact and Robust Stainless Steel Housings
Withstand shaft loads of up to 300 N
Up to IP69K Environmental Rating
Durable Speed Control SystemIXARC magnetic incremental encoders can provide an impressive combination of accuracy and durability for wind turbine speed control systems. POSITAL’s reliable incremental encoders are available with environmental protection ratings of up to IP69K. They can be programmed to provide up to 16,384 pulses per revolution, with a choice of Push-Pull (HTL) or RS422 (TTL) communications interfaces. Resolution and interface parameters can be set quickly and easily through the use of POSITALs UBIFAST programming tool.
Accurate Azimuth FeedbackIXARC absolute multiturn encoders with 30 bit total resolution are used to provide absolute position measurement for the azimuth control systems that adjust the orientation of the nacelle in response to changes in wind direction. In addition to high resolution, such applications also require sensors that can stand up to the mechanical loads that can be imposed when the nacelle structure is exposed to strong winds. Robust, tried-and-tested encoders ensure better reliability and operating safety, which helps users reduce downtime and the associated costs.
Wide Selection of Mounting Fixtures for Rotary Encoders
POSITAL offers a wide selection of accessories that simplify sensor installation and help ensure a long and reliable service lives for both for sensors and the machinery they are monitoring.
Mating connectors of different types and lengths are available to ensure reliable electrical connections. Using mounting accessories from POSITAL will minimize wear and tear on encoders and help ensure reliability and longevity. Interface modules and displays provide users way of monitoring sensor outputs at a convenient location close to where the sensor is mounted.
Different industrial environments pose different challenges, which is why POSITAL is continuously adding new accessories to its portfolio. The quality of the accessories can be as important as the quality of the encoder or inclinometer. This is why we encourage users to rely on field-tested POSITAL accessories.

Ideal for Industries in
POSITAL offers unique sensors to meet the needs of industries such as:
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.
