Nemicon – Hollow Shaft Multi-Turn Encoder 38HA-MS

Hollow Shaft Multi-Turn Encoder (φ38mm)

Brand : Nemicon

The Nemicon 38HA‑MS Series is a hollow shaft multi‑turn absolute encoder designed to provide reliable absolute position feedback in industrial automation, robotics, and precision motion systems. Its 38 mm outer diameter and hollow shaft construction allow direct mounting onto machine or motor shafts, reducing the need for couplings and simplifying installation. Using magnetic absolute sensing technology with multi‑turn capability, the encoder maintains accurate absolute position data across multiple revolutions without requiring batteries.

The 38HA‑MS encoder supports high resolution single‑turn and multi‑turn position tracking, making it suitable for applications where precise angular position information is critical. It offers communication interfaces such as BiSS‑C or SSI for integration with PLCs, motion controllers, and automation systems. With durable mechanical design and stable signal output over a wide operating temperature range, the encoder delivers dependable feedback for complex motion control tasks in harsh industrial environments.
