The Kuebler A02H is an industrial-grade optical rotary encoder tailored for demanding motion control tasks involving large shafts and rugged environments. Engineered with a substantial Ø 100 mm housing and built to accommodate hollow shafts up to 42 mm — including sizes like 20 mm, 25 mm, 30 mm, 38 mm, 40 mm, 5/8", and 1 1/4" — it’s perfectly suited for integration into large rotary systems and heavy-duty drives.
The encoder supports various flange types such as Ø 100 mm and Ø 115 mm, enabling easy installation across a range of industrial frameworks. It offers a maximum resolution of 5000 pulses per revolution (PPR), delivering accurate and high-frequency feedback even at speeds up to 6000 min⁻¹. Operating reliably between -40°C to +80°C, the encoder carries an IP65 protection rating that ensures resistance to dust, humidity, and mechanical stress.
Connectivity options include radial cables and M12/M23 radial connectors, while electrical interfaces like TTL / RS422, Gegentakt, and SinCos ensure seamless compatibility with various drive systems. Power flexibility is ensured through 5 V DC, 5–30 V DC, and 10–30 V DC supply ranges. Optional variants include EX protection for zone 2/22 and extended resolution formats, making the Kuebler A02H Encoder an ideal solution for hazardous, high-performance industrial environments.
The Kuebler A02H Encoder is specifically engineered for large-scale rotary motion systems where robustness and accuracy are non-negotiable. Its wide through hollow shaft compatibility makes it ideal for direct mounting onto main shafts in heavy machinery, steel rollers, mining conveyors, and industrial fans.
In wind energy systems, it delivers precise incremental feedback for pitch and yaw control mechanisms, enhancing turbine performance and safety. In crane systems and hoisting equipment, the encoder ensures safe and synchronized motion by accurately tracking shaft position even under dynamic load conditions. Its high protection rating and temperature resilience make it a reliable choice for outdoor and factory environments with dust, oil, and vibration.
If you're managing large equipment where failure is not an option, the Kuebler A02H offers dependable incremental encoder feedback with mechanical durability, electrical flexibility, and proven German engineering — trusted by industries worldwide.
