Professional power tools like electric screw drivers, drills, hammer drills, torque wrenches, nut-runners and fasteners are equipped with position-, speed- and torque-sensors in order to guarantee precise, swift and safe operation. The working environment of these sensors is very dirty and subject to heavy vibrations and shocks. As a POSICoder encoder chip and disc have a mass below 1 g, they are particularly suited to withstand strong vibrations. The small dimensions and immunity against magnetic fields are additional features that are very helpful to integrate inductive encoder chips and scales or discs into an electrically powered lightweight handheld tool.
Which encoder chip is most suited for application in electric power tools?
The PO1020 inductive encoder chip with a wide temperature range up to 125°C, because the temperature of these compact handheld power tools may be very high during operation.
