Rotary encoder
For the labeller to be used with automatic speed adjust-
ment, a rotary encoder must be connected. The rotary
encoder communicates the conveyor belt speed to the
label dispenser.
Requirements for rotary encoder:
– Permitted sensor types: Push-Pull or PNP
– Recommended: Push-Pull
– Required specification data for rotary encoder:
