Description

Shunt Mode force sensors are the most frequently used design. They are constructed in two layers of flexible polymer. One layer is printed with a proprietary force-sensing ink and the other with conductive ink printed with interdigitating electrodes. The two substrates are then positioned facing each other and adhered using a spacer adhesive in the middle. The inter-digitating electrodes can be designed in various configurations depending on the application including, but not limited to: various patterns to influence sensitivity, various conductors including silver, copper, carbon and blends, or on a printed circuit board (PCB).

When a force is applied to the device, the shunt or shorting circuit is complete. The more force applied to the TPE-502, the more conductive the output.

Tangio’s FSR range has three options for the connecting end of your sensors. Simply add the option at the end of the part number. For example, a TPE-502 with option A connectors has the part number TPE-502A.

Option A: The tail on the FSR ends with a pair of exposed carbon traces, for a direct connection.

Option B: The FSR tail ends in bronze/tin plated solder tabs.

Option C: Bronze/tin plated termination pins are enclosed in CNT female housing.

At Steadlands, we carry the ‘B’ variant of FSR, with a minimum order quantity of 10 units. Types ‘A’ and ‘C’ are available by special order, and have a minimum order quantity of 100 pieces. Please contact us to discuss this further.
