The FlexiForce A401 is our standard piezoresistive force sensor with the largest sensing area. It is available off-theshelf for easy proof of concept and is also available in large volumes for design-in applications. The A401 can be used with our test & measurement, prototyping, and embedding electronics, including the OEM Development Kit, FlexiForce Quickstart Board, and the ELF™ System*. You can also use your own electronics, or multimeter.
• Thin and flexible.
• Easy to use.
• Convenient and affordable.
PHYSICAL PROPERTIES -
Thickness - 0.203 mm (0.008 in.).
Length - 56.9 mm (2.24 in.)**.
Width - 31.8 mm (1.25 in.).
Sensing Area - 25.4 mm (1 in.) diameter.
Connector - 2-pin Male Square Pin.
Substrate - Polyester.
Pin Spacing - 2.54 mm (0.1 in.).
Standard Force Ranges - 111 N (0 - 25 lb) ; 31,138 N (0 - 7,000 lb).
Measurement ranges of 0-1 lb and 0-7,000 lb are achievable with the A401 sensor by utilizing the recommended circuitry. The force range can be extended by reducing the drive voltage, VT, or the resistance value of the feedback resistor, RF. Conversely, the sensitivity can be increased for measurement of lower forces by increasing VT or RF.
