Nemicon – Hollow Shaft Single-Turn Encoder AHS2

Hollow Shaft Single-Turn Encoder (φ38mm)

Brand : Nemicon

The Nemicon AHS2 Series is a hollow shaft single‑turn absolute rotary encoder engineered for high‑precision position feedback in industrial automation and motion control applications. Its hollow shaft design enables direct mounting onto machine or motor shafts without the need for additional couplings, simplifying installation and reducing mechanical complexity. Utilizing magnetic absolute sensing technology, the AHS2 provides accurate single‑turn position data without requiring a battery backup, making it suitable for compact drives, robots, and automated machinery where space and reliability are critical.

The AHS2 encoder supports high resolution single‑turn measurement via industrial communication interfaces such as SSI or BiSS‑C, enabling easy integration with PLCs, motion controllers, and control networks. Its robust mechanical and electrical design ensures dependable performance over a wide temperature range and in demanding environments. With low maintenance and stable output, the AHS2 series delivers consistent absolute feedback for precise motion control.
