Precise angle and rotation measurements are essential in modern industry. Whether in medical devices, mobile machines or renewable energy systems - in many applications, not only the angle of rotation but also the number of revolutions must be reliably recorded. This is precisely where multiturn technology comes in.

The new [Vert-X 46MT ](https://www.contelec.ch/en/products/product-lines/multiturn-rotary-encoders/vert-x-46-mt)from Contelec is a high-precision multiturn encoder that works without a battery or gearbox and stores absolute position data over several revolutions. But what makes multiturn encoders so special - and why should a battery-free solution be preferred?

## What is a multiturn encoder?

A multiturn encoder not only records the current angle of a rotary movement, but also counts the number of complete revolutions - even over longer periods of time and regardless of whether the system has been switched off in the meantime.

### How does this work?

- Classic encoders only measure a single rotation (0-360°)
- Multiturn encoders also count how many times this full rotation has taken place
- This information is crucial for applications in which large travel distances or multiple rotational movements need to be recorded

### What is the difference between battery-free multiturn encoders?

Traditionally, multiturn encoders store rotation information using batteries or mechanical gears. The [Vert-X 46MT](https://www.contelec.ch/en/products/product-lines/multiturn-rotary-encoders/vert-x-46-mt) requires neither.

- No battery in the sensor / no risk of disposal / no risk of failure  
  ➡️ Maintenance-free, more reliable and more sustainable
- No mechanical gearbox  
  ➡️ Wear-free and durable, even at high speeds
- Independent revolution counting  
  ➡️ Stores revolutions even when the sensor is switched off - without an external energy source

## Why battery-free multiturn encoders are revolutionizing the industry

### Mobile machines & vehicle technology

- Steering & drive systems: Monitoring steering movements in off-highway vehicles
- Lifting systems: Detecting the lifting height in forklift trucks or construction machinery
- Swivel mechanisms: Control of crane booms and work platforms

### Medical technology

- Positioning of operating tables & patient couches: Accurate measurement of height and rotation adjustments
- Precision movements in diagnostic devices: Ensuring exact processes in imaging procedures

### Renewable energies

- Rotor blade adjustment in wind turbines: Precise adjustment to wind conditions
- Tracking systems for solar panels: Maximizing energy yield through optimal alignment
