Digisensor
The Digisensor (Figure 2) is a small, rugged device that converts joystick handle movement into an
electrical signal. The Digisensor requires only two wires, and can transmit its signal to a Superflex
controller up to 500 feet away. Figure 18 (on page 19) shows the various features of the Digisensor.
A potentiometer embedded in the Digisensor measures
the joystick controller’s movement (usually with a gear).
The potentiometer is also used for mounting the
Digisensor. Two red LEDS indicate the Digisensor
position (whenever power is applied). The “Direction
A” LED turns on when the potentiometer shaft is turned
counter-clockwise, and the “Direction B” LED turns on
when rotated clockwise. When the Digisensor’s shaft is
centered (turned halfway between its ends) both LEDS
will be on. The section titled “Troubleshooting -
Digisensor” has additional details.
Two wires connect the Digisensor to the system. The red wire connects to the +12 or +24 volt power, and
the black wire connects to one of the Superflex inputs. Figure 3 shows typical wiring for a single axis
joystick controller. In this example, a microswitch turns on the Digisensor when the joystick handle is
moved from its center or “off” position.
