Kusaba Engineers Private Limited

Specification / Parameters

Motion control applications – ranging from factory automation to control systems for mobile machines – require precise, real-time information about the physical location of mechanical equipment. Absolute rotary encoders can provide precise and unambiguous measurements without losing track of their position due to a temporary loss of instrument power.

• Maintain Position Information When Power is Lost
• Wiegand Technology means No Battery Backup Necessary – Never Change Batteries
• Compact Size - Down to 36 mm Ø
• Stainless Steel, ATEX and SIL Encoders Available
• High Shock and Vibration Resistance

Singleturn Encoders

Singleturn encoders are providing a measurement range of 360 degrees (one turn). When the shaft of the encoder is turned by more than 360 degrees, output characteristics in subsequent turns will be equal to the first turn.

Examples: output@361 degrees = output@1 degree, output@720 degrees = output@360 degrees.

Multiturn encoders

Multiturn encoders provide a measurement range of more than 360 degrees by additionally measuring the number of revolutions. The output signal is based on the number of revolutions as well as on the shaft position within one turn.

Example: The output signal/value after 3.5 turns (starting from zero) will be 7 times higher than the output after the first half turn.

Multiturn Measurement Technology

 

The Hall-Effect based sensor system is the singleturn stage of the absolute encoders. However, it does not enable the encoder to count revolutions if the external power supply is disconnected. POSITAL solves this problem by means of an energy harvesting system based on the WiegandEffect which requires no batteries or gears. Using batteries brings about a lot of disadvantages, since they have a limited lifespan, a considerable weight, and contain harmful substances. Gear units bring weaknesses of their own being large, complex, costly and vulnerable to shock and vibration. Regardless of the rotational speed, even at nearzero, the energy harvesting system generates short, powerful voltage pulses which supply sufficient power to the counting electronics in absolute encoders. Thus, the revolution counter is independent of any external power supply. This principle, which has proven itself since 2005, enables maintenance-free reliable measurement of absolute positions even in demanding environments for years to come.
