Size matters, and in the world of industrial automation, providing exceptional performance in a highly compact package can be an enormous advantage.

With this in mind, encoder manufacturer Posital has unveiled a fully functional prototype of their new miniature multi-turn kit encoder for integrated motor feedback. With a diameter of only 22 mm and a height of 23 mm (0.87”/0.9”), the new device is the world’s smallest multi-turn kit. 

It features a self-powered rotation counter that does away with the need for backup batteries or complex gear systems. Posital’s extremely trim 22 mm magnetic Kit Encoders are designed for builders of: 

  • Servomotors
  • Feedback-controlled stepper motors
  • Microdrives
  • Miniature robots
  • Other machines where high-precision position feedback is required and space is at a premium

Like their “big brothers,” the new 22 mm kits are reliable, accurate and simple to install. Unlike resolvers, they cover a multi-turn measurement range and provide digital output. 

Compared to optical kits, they are more rugged and more resistant to contamination by oil, dust or moisture. They offer 17-bit electronic resolution and a multi-turn measurement range of up to 32 bits. Vendor-neutral SSI and BiSS C interfaces are supported. Installation of the 22 mm kits is very straightforward and can be done under normal factory conditions.
