Where Are Single-Turn Encoders Used?

If you are an engineer and you ask where single-turn absolute encoders are used in industrial automation, the honest answer is almost everywhere. The primary consideration is the accuracy of the angular position relative to one revolution. 

When fast, accurate feedback is a must, no matter the application, a single-turn encoder is the ideal rotary position sensor solution; its positioning is instant, and no homing or referencing cycles are required.  

Other than that, a single-turn absolute encoder is also used in aerospace and defense, as well as in medical technology and scientific instrumentation.  As the industrial side is taken into consideration, we have been doing this for years at Briter Encoder, supplying these to manufacturers that require a sensor that works, the out-of-the-box kind, and this article is designed to help you do exactly that.

As they provide an absolute position reading as soon as power is applied, they eliminate the delays inherent in incremental encoders that require a reference point. This makes them excellent for use as industrial automation encoders in applications where downtime is not allowed.

What industries commonly use single-turn absolute encoders?

A single-turn absolute encoder is widely used in industries that require highly precise, short-range motion control. Some of the most common industries include: 

• Robotics and automation for joint positioning and motion accuracy 
• Steering angle sensing in cars and steering line automation in the production line 
• Positioning of wind turbine blades or solar trackers for driving renewable energy
• Handling and logistics materials to foster control of the conveyor and sorting system  
• Medical equipment for exact positioning within diagnostic or surgical devices

Likewise, the common denominator is that they all require reliable feedback not complicated by multi-turn tracking.

Are single-revolution position sensors suitable for robotic arm applications?

A pertinent question arises: can single-turn absolute encoders improve accuracy in robotic systems? The answer is yes. A rotary position sensor is primarily suitable for key robot arm motion control, which requires measuring small angular ranges. Be that as it may, the subsequent angle of rotation must be measured as more than one turn. However, you can choose a multi-turn one when you need much higher accuracy and resolution. 

Likewise, here are the key aspects of how a single-revolution position sensor drive benefits when linked with robotic arm applications, which we at Briter Encoder place emphasis upon:

• They minimize echoes of error downstream as compared to older incremental systems
• Assisting with fine and repeatable actions, essential for high-resolution readings
• Remaining priorly functional in tough industrial settings, because of their robust design

In applications such as robotic arm pick-to-place, welding, and robotic assembly, this robustness directly impacts production performance and accuracy. 

Can one-turn position encoders be used in CNC machines?

At Briter Encoder, our one turn position encoder is primarily used in key CNC machines, especially on core rotary axes, and in permanent magnet servo motors for key rotor commutation. Since the encoders reset to zero every 360 degrees, they are generally used for longer linear axes where the tool must travel through multiple rotations. 

CNC operations require tolerances to be kept to a minimum, but tight tolerances are not possible with a pulse counter because it doesn’t measure at a single point. It is particularly useful in high-speed machine environments where the accuracy of positioning matters very little and may translate into errors in part quality.

 The preferred choice for CNC manufacturers is one-turn because it eliminates setup and calibration time on the shop floor by providing immediate readiness after installation. 

Are singular-turn encoders good for conveyor belt or automation systems?

A singular-turn encoder can deliver excellent performance for tracking conveyor speed, key motor control, and even pivoting in its respective applications. Further, they offer highly precise, even real-time angular feedback and instantly recall your exact position upon core start-up. Likewise, a single-encoder actively excels within:

• Conveyor synchronization and even speed, wherein they offer an accurate set of belt speeds and even aid in synchronizing the multiple conveyor belts. 
• A single-turn encoder actively offers rotor-to-stator feedback inside the servo motors to drive optimal torque and speed control.
• Driving precise partial rotations, which is ideal for tracking the pivotal arms and even sorting the gates or tilt mechanism

Where a rotary mechanism such as a pulley, roller, or an indexing table requires one-turn accuracy, single-turn encoders are well suited for conveyor belts and advanced automation systems. They are industrial automation encoders that help synchronize motion among several machine stations, reducing jams, misalignments, and unscheduled downtime.

Their real-time feedback feature also brings benefits for predictive maintenance: Operators can identify positioning irregularities in advance, which could otherwise lead to costly breakdowns. This reliability can be the key to a successful shift or a failed one for facilities operating automation lines that run 24/7. 

Conclusion
