The 4B heavy duty stainless steel Rotech rotary shaft encoder is used
primarily for protecting equipment and personnel from dangerous
underspeed/belt slip conditions in extreme environments. 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 1/2 in. UNC Rotech Bolt. The unit is secured to
the shaft with this bolt and is able to move with the shaft. No guards
are required as the rotating components are encased inside the housing
of the encoder. No brackets are required as the encoder couples directly
to the end of the shaft and floats with the shaft.
