Product Description

The RHPH0118 precision gearbox is a high-performance servo reducer designed for industrial automation, robotics, and aerospace applications. It features a harmonic drive mechanism, ensuring smooth motion control with near-zero backlash and exceptional positioning accuracy. The unit operates within a voltage range of 12-48V DC, supporting temperatures from -10°C to +85°C. With multiple input/output interfaces (2 analog/digital inputs, 1 RS-485 port, and 2 PWM outputs), it seamlessly integrates with motor controllers and PLC systems. The RHPH0118 harmonic drive offers a gear ratio range of 30:1 to 160:1, delivering torque capacities up to 18Nm while maintaining 85% efficiency. Its compact 72mm diameter housing, IP65-rated construction, and 420g weight make it ideal for space-constrained installations. Key advantages include ultra-low friction losses, 0.1 arc-minute repeatability, and vibration damping capabilities, though requires precise alignment during installation. Typical applications include CNC machinery, medical devices, and precision measurement systems.
