Rotech Encoder

The 4B Rotech Encoder is used primarily for protecting equipment and personnel from dangerous underspeed / belt slip conditions. Other applications include accurate speed control, direction of rotation detection, gate position indication and counting the number of revolutions of the shaft.

An inductive sensing device in the body of the encoder detects a steel rotor. On slow speed or accurate position control, a photo diode detects the slots on a steel disk. One pulse is created for each rotor or slot so the unit can be connected directly to a PLC/computer or 4B control module. The shaft to be monitored is drilled and taped to take the M12 Rotech Bolt. No guards are required as the rotating components are encased inside the aluminium housing of the encoder. No brackets are required as the encoder couples directly to the end of the shaft and floats with the shaft.

Polyester and stainless steel versions are also available for offshore and other highly corrosive applications."
