STD-79
The STD-79 is a contactless, optical, reflective, absolute position sensor that delivers high-precision single-turn feedback in a low-profile design. Its integrated dual sensing heads and Duplus Core redundant technology provide accurate, reliable, and stable performance in demanding motion control applications.
The STD-79 supports SSI and BiSS-C interfaces, offering 18–22-bit resolution and ±2 mdeg accuracy for precise and repeatable position feedback. Its wide assembly tolerances simplify alignment and installation, making it a plug-and-play solution for OEMs and system integrators.
Built to operate under harsh conditions, the STD-79 combines robust mechanical construction, low power consumption, and high vibration and shock resistance, ensuring long-term stability in automation, robotics, and precision drive systems.
