The story behind an incremental encoder’s 22-year legacy

A picture’s worth a thousand words…or 22 years of service! Encoders are a crucial part of industrial automation, providing data on speed and position in several applications. Whether it’s monitoring the speed of a conveyor belt or making moves on an autonomous mobile robot, an encoder needs strength and endurance if it’s going to live a life of tracking speed, angles, and positions. Cue the trusty encoder from SICK.

The Duty of an Encoder

Encoders are sensors that translate motion into an electrical signal for a control device. They provide data like position, angle, and rotation counts. This data can be used to determine speed and position, making encoders the perfect solution for accurate position and speed detection in industrial automation.

Encoders Everywhere!

SICK offers an extensive portfolio of encoders, ranging from the common absolute and incremental rotary encoders to linear and wire draw encoders. On the incremental encoder pictured above, you will see its label says “SICK | Stegmann.” This is because SICK acquired Stegmann, a producer of encoders, in 2002. Acquiring Stegmann over two decades ago broadened SICK’s offering, expanding their expertise in the motion control sensing market.

Common Encoder Applications

Encoders find their way into a LOT of applications in the automation industry, but here are some of the most common applications you will see them serving:

1. Conveyor Systems: Monitoring and controlling the speed and position of items on the belt.
2. Robotics: Providing precise position feedback for robotic arms and autonomous mobile robots.
3. Automotive Industry: Used in assembly lines for tasks such as welding, painting, and quality control.
4. Packaging Machines: Ensuring accurate positioning and speed control for packaging processes.
5. Elevators and Escalators: Monitoring the position and speed for safe and efficient operation.

A Legacy of Reliability

The trusty encoder pictured above served its duty in a material handling/conveyor application with a global tire manufacturer. This encoder, produced in 2003, has demonstrated remarkable durability and reliability, operating flawlessly for 22 years. This longevity is a testament to the quality and robustness of SICK products.

Quality and Innovation

Since acquiring Stegmann, SICK has continued to innovate and produce robust sensors that meet the demanding needs of industrial automation. The commitment to quality and continuous improvement has been a cornerstone of SICK's success, ensuring that their products stand the test of time.

Employee Pride

“This good old boy was produced in 2003, when Stegmann was bought by SICK. Quality was a key point at Stegmann, as well as at SICK. Since that time, SICK has produced and developed lots of new robust sensors! I’m so proud to work in this company!” commented David Zeller, application engineer at SICK.

Investing for the long haul

The story of this incremental encoder is not just about a piece of hardware; it's about the dedication to quality, innovation, and reliability that SICK and Stegmann embody. This 22-year legacy is a testament to the enduring value of investing in high-quality industrial automation solutions.
