POSITAL 22mm diameter magnetic encoder is the world’s smallest.

POSITAL unveiled a fully functional prototype of their new miniature multi-turn kit encoder for integrated motor feedback. With a diameter of only 22mm and a height of 23mm (0.87/0.9 inch), the new device is the world’s smallest multi-turn kit. Featuring a self-powered rotation counter, the encoders 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, the company says. They offer 17-bit electronic resolution and a multi-turn measurement range of up to 32 bits. The encoder line supports vendor-neutral SSI and BiSS C interfaces and features integrated self-calibration and an integrated temperature sensor for diagnostics.
