Servo Motor Incremental Series
An incremental encoder provides precise speed and distance feedback. Since few sensors are involved, the encoders are relatively simple and inexpensive.
An incremental encoder provides only relative position information, where the feedback signal is always referenced to a start or home position.
Heavy Duty: demanding environment with a high probability of contaminants and moisture, higher temperature, shock, and vibration requirements as seen in pulp, paper, steel, and wood mills.
Industrial Duty: general factory operating environment which requires standard IP ratings, moderate shock, vibration, and temperature specs as seen in food and beverage, textile, generally factory automation plants.
Light Duty/Servo Motor: controlled environment with high accuracy and temperature requirements such as robotics, electronics, and semiconductors.
Servo Motor Series:
Servo encoders, unlike both heavy duty and industrial encoders, actually reside inside a motor housing. Because it is in a contained environment, it doesn’t have strong sealing, but it has excellent temperature resistance and reliable shock/vibration resistance (which fits its operating environment). Because of its location, server encoders are smaller and are made for small to mid-sized motors, especially servo and stepper motors.
