Rotary Potentiometer - WDA-D35-D4C

ID: 3583_0
Recommended for new designs: Phidgets Inc. is not the original manufacturer for this product, but we intend to sell it (or a similar replacement with a compatible form, fit and function) for as long as it is available from the supplier.

This industrial rotary potentiometer can rotate continuously and connects to an Analog Input or VINT Hub port.

The WDA rotary potentiometer allows positional feedback for a rotating part in your application. It can also be used as a dial to control variables such as volume, brightness, or sensitivity.

It has 360° of mechanical travel and 345° of electrical travel, meaning that it can be used for measuring continuous rotation with a small blind spot between each rotation.


This sensor can be used with any device with an analog input. Simply cut and connect a 3-wire Phidget cable as described in the Phidget Cable section on the Connection & Compatibility tab.

Phidget Cables


To easily connect this potentiometer to a Phidget we recommend you use a Phidget cable. Just snip off the connector from one end of the Phidget cable, strip the ends of the wires and solder them to the pins on the potentiometer. The green terminal on the potentiometer is the wiper, and should be soldered to the data line. The other two terminals should be soldered to power and ground. Soldering ground to the middle terminal will result in increasing voltage ratio with clockwise rotation, while soldering power to the middle terminal will result in decreasing voltage ratio with clockwise rotation. You can solder multiple cables together in order to make even longer Phidget cables, but you should be aware of the effects of having long wires in your system.

Interface Boards and Hubs

This potentiometer can be read by any Phidget with an Analog Input or VINT Hub port. It will connect to either one using a Phidget cable; see the diagram in the Phidget Cables section below for wiring instructions. VINT Hub ports can behave just like Analog Inputs, but have the added flexibility of being able to be used as digital inputs, digital outputs, or ports to communicate with VINT devices. For more information about VINT, see the VINT Primer.
