STN-60
The STN-60 is a contactless optical reflective absolute position sensor that provides high-precision single-turn feedback for compact and demanding motion control applications. Its integrated dual sensing heads and Duplus Core redundant technology deliver accurate, reliable, and stable performance in challenging environments.
The STN-60 supports SSI and BiSS-C interfaces, delivering 18–22-bit resolution and ±2 mdeg accuracy for precise, repeatable feedback. Its low-profile 60 mm design and wide assembly tolerances simplify installation and alignment, making it a plug-and-play solution for OEMs and system integrators.
Designed for harsh conditions, the STN-60 combines robust mechanical construction, low power consumption, and high vibration and shock resistance, ensuring long-term stability in automation, robotics, and precision drive systems.
