4B Rotech Rotary Shaft Encoder – Stainless Steel

The 4B heavy-duty stainless steel 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 stainless housing suits washdown and corrosive environments.
