Optimum 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.
Optimum encoder is also called light duty encoder, which is used in more consumer-facing applications like office electronics (copiers, faxes, and computer accessories), and laboratory and medical equipment.
They have good performance for temperature, shock/vibration, and sealing, with better speed performance and high precision.
