Speed transducer for tractor
Note the following if the speed transducer is
tted to the tractor or vehicle.
The speed transducer is an inductive type. It
requires a metallic protrusion (e.g. bolt head)
to pass by it to trigger a signal. A diode on the
transducer will ash when a signal is detected.
Recommended distance between protrusion
and transducer is 3 to 5 mm.
