Customization
Customize the size, shape, and even the number of tracks. Such custom requests, for example, can be: multiple
ganged sensors (up to 40 tracks); serpentine active area track; custom lengths 10mm-2000mm; custom rotary
diameters, etc. Feel free to contact Spectra Symbol with your custom request at [email protected] or
(888)795-2283..
How It Works
In simple terms, the HotPot membrane potentiometer is a resistive element, which comprises a conductive
resistor, a sealed encasement and a simple wiper assembly. A membrane potentiometer can also function as a
voltage divider.
The HotPot is a three-wire system with two resistive output channels and an electrical collector channel.
Top Circuit (Collector)
Circuit Spacer
Bottom Circuit (Resistor)
Bottom Adhesive
By pressing a wiper down onto the top circuit the HotPot produces the desired electrical output. The "wiper" is a
non-conductive mechanism that depresses the top circuit actuating the potentiometer from the outside of the
element. The top and bottom circuits are separated by 0.15mm (0.006") of spacer adhesive build-up and contact
between the circuit occurs by pressure (usually 1-3 Newtons) from the wiper on the top circuit, pushing down until
the top circuit connects with the bottom circuit to create a potentiometric output.
The construction of the wiper design can adapt to any application because most materials can serve as the wiper:
plastics, metals, sliders, rollers, wheels, etc. Also, the HotPot can also be manually (hand) actuated.

Wiper
Typical wiper materials are delrin, plastic injection molded products, metal rollers with back-loaded springs,
sliders attached to lead-screws, etc. With small quantities, an off-the-shelf solution might be easier, while with
higher quantities or space limitations a custom wiper may be required.
The stock 1-3 Newton wiper is an excellent product for most applications. In case of unique applications,
extreme environment or cycle needs, it is recommended to seek the advice of the Spectra Symbol Design
Department. The selection of the correct wiper (material, form) can affect the life cycle and electrical output of
the SoftPot.
