Single-turn potentiometer HSM30 series

manualHall effectfor industrial applications

Overview

• Contactless magnetic rotary potentiometer (Hall effect) for industrial position sensing.
• Model HSM30 — single-turn, bushing mount with endless 360° mechanical rotation.
• Available in single or dual outputs; multiple options for outputs and supply voltage.

Key Features

• Non-contact Hall-effect sensing for extended life and stable output.
• Single-turn position measurement with continuous 360° mechanical rotation.
• Bushing or flange mounting options for panel and shaft installations.
• Low rotating torque and high rotational life (~50,000,000 cycles).
