Absolute encoders make up part of our product range. They are a rotary sensing device that provide feedback on exact position at any given time in a range of applications that require some control or monitoring.
With absolute encoders the position is always retained, with or without power. If movements are made without the encoder being powered, when the power is reapplied, the encoder will know its new position.
Single or Multi-Turn Absolute Encoders
Absolute encoders can either be single or multi-turn. Single turn encoders are more suitable for short travel applications where position measurement is required within a single turn of the encoder. Multi-turn encoders are a better option for applications where complex or lengthy position measurements are involved.
Advantages of Absolute Encoders
Some advantages to the encoders available here at Variohm are:
- Non-volatility memory
- Continuous reading of position is not required
- No battery backup or gear function due to the patented ‘Endra’ technology from our supply partner Wachendorff.
- No traditional optical disk making it more cost effective in comparison
- High resolution with up to 16-bit single and 44-bit multi-turn.
Where are Absolute Encoders Used?
Absolute encoders can be found in applications across many industries. Due to their accurate measurements, they are a popular choice for high demanding applications. Some examples are:
- Medical & Industrial Robotics
- Civil & Underground Engineering
- Cleaning Machines
- Cranes
- Elevators – Check out our blog all about sensors in elevators.
- Satellite Comms
- Machine Packaging
- Radiation Therapy
