4B Rotech Rotary Shaft Encoder – Polypropylene

The 4B heavy-duty polypropylene Rotech rotary shaft encoder protects equipment and personnel from dangerous underspeed and belt-slip conditions in extreme environments. It's also used for accurate speed control, direction-of-rotation detection, gate-position indication, and counting shaft revolutions.

An inductive sensor in the encoder body detects a steel rotor; for slow-speed or accurate position control, a photodiode reads slots on a steel disk, producing one pulse per rotor slot. The corrosion-resistant polypropylene housing suits chemically aggressive environments.

Features

• Corrosion-resistant polypropylene construction
• Underspeed, belt-slip, speed control, direction and position sensing
• Inductive + photodiode sensing for accurate low-speed output
