Xizi Otis Elevator TAA633K151 Hollow Shaft Main Unit Encoder with 512 PPR/1024 PPR and IP54 Protection

The TAA633K151 is a hollow-shaft incremental rotary encoder designed by Hengstler Hohner specifically for Otis Gen2 series elevator traction machines. This brand new encoder is also compatible with SIGMA brand elevators and serves critical functions in elevator speed detection, position monitoring, and closed-loop control systems to ensure precise leveling accuracy and operational safety.

• Incremental A/B quadrature pulse output for precise traction machine speed and car displacement measurement
• Hollow-shaft design eliminates need for additional couplings, reducing mechanical errors
• Optical sensing technology ensures stable signal transmission with fast response (pulse jitter ≤ ±1°)
• Ideal for high-frequency start-stop elevator operating conditions
• Built-in short-circuit and reverse connection protection prevents circuit damage from wiring errors
• Enhanced vibration and shock resistance for reliable performance in elevator mechanical environments
• Anti-electromagnetic interference capability suitable for complex elevator machine room environments
• Supports real-time position and speed feedback for elevator control systems
