14 Bit or 19 Bit Encoder: Which One Do You Need?

When it comes to precision motion control and industrial automation, choosing the right encoder is crucial. Encoders convert mechanical motion into electrical signals, enabling machines to know their exact position. Among absolute encoders, two popular options are the 14 bit absolute encoder and the 19 bit absolute encoder. For applications requiring solid mechanical coupling, their solid shaft versions—the 14 bit absolute solid shaft encoder and 19 bit absolute solid shaft encoder—are widely used.

Understanding Absolute Encoders

An absolute encoder provides a unique position value for every shaft angle. Unlike incremental encoders, which only track changes in position, absolute encoders give precise location information instantly, even after power loss. This feature makes them essential in robotics, CNC machines, automation equipment, and other precision machinery.

14 Bit vs 19 Bit Absolute Encoder

The difference between a 14 bit absolute encoder and a 19 bit absolute encoder lies in their resolution:

• 14 Bit Absolute Encoder: Offers 16,384 unique positions per revolution (2¹⁴), sufficient for many standard industrial applications.

• 19 Bit Absolute Encoder: Provides 524,288 unique positions per revolution (2¹⁹), ideal for high-precision systems where extremely fine motion detection is required.

Choosing between the two depends on the required accuracy and resolution of your application. Higher resolution encoders offer better precision but may cost more and require compatible electronics.

Solid Shaft Versions

For applications needing direct mechanical connection to a motor or rotating system, the 14 bit absolute solid shaft encoder and 19 bit absolute solid shaft encoder are excellent choices. Solid shaft encoders are robust and easy to mount, providing reliable performance in demanding environments.

Jilin Weiguang Electronic Technology Co., Ltd. offers the PAL90S series, which includes both 14 bit and 19 bit solid shaft absolute encoders. These encoders deliver high accuracy, durable construction, and flexible output options such as binary or Gray code, making them suitable for a wide range of industrial applications.

Applications

Absolute solid shaft encoders are commonly used in:

• CNC machines and precision milling equipment

• Industrial robots and servo motors

• Automated assembly lines

• Energy systems and instrumentation

Choosing the right encoder ensures smoother operation, higher precision, and reduced downtime in critical industrial systems.

Which One Should You Choose?

• Use a 14 bit absolute encoder or 14 bit absolute solid shaft encoder for standard industrial tasks where moderate precision is acceptable.

• Opt for a 19 bit absolute encoder or 19 bit absolute solid shaft encoder for high-precision tasks that demand extremely fine position resolution.

In summary, selecting between 14 bit and 19 bit absolute encoders depends on your application’s precision requirements, mechanical setup, and budget. The solid shaft versions provide the added benefit of robust mechanical integration, making them ideal for demanding industrial environments.
