Nemicon – Hollow Shaft Single-Turn Encoder ASC-HP

Hollow Shaft Single-Turn Encoder (φ50mmmm)

Brand : Nemicon

The Nemicon ASC‑HP Series is a hollow shaft single‑turn absolute rotary encoder engineered for precise angular position feedback in industrial automation and motion control systems. With its hollow shaft design, this encoder can be mounted directly onto a machine or motor shaft without additional mechanical couplings, simplifying installation and reducing system complexity. Utilizing magnetic absolute sensing technology, the ASC‑HP provides accurate single‑turn position data without requiring a backup battery, making it ideal for servo systems, robotics, and compact automated machinery.

The ASC‑HP encoder supports high resolution single‑turn measurement and offers industry‑standard communication interfaces such as SSI and BiSS‑C for seamless integration with PLCs, motion controllers, and automation networks. Designed for stable electrical performance and mechanical durability, it operates reliably across a wide temperature range and in challenging industrial environments. With dependable absolute feedback and versatile interfacing, the ASC‑HP series enhances precision control in demanding motion applications.
