Description

  • Calibrated Capacitive Force Sensor 8mm 10N (2.2lb)
  • Features a single tact sensor and interface board
  • Is a single element tactile pressure sensor
  • Supports the standard (100 Kbits/s) clock rate

The Calibrated Capacitive Force Sensor 8mm 10N (2.2lb) is a single element tactile pressure sensor that accurately and reliably quantifies applied force combined with a simple interface board offering a 0 to 2 V analog output for immediate Data Acquisition (DAQ) integration and an I2C based interface for integration into embedded systems.

The sensor is plugged into the FFC connector on the green interface board (with the sensor connector pads facing upward). The analog output swings from 0 to 2 V, with the valid working output ranging from 0.5 to 1.5 V. The SingleTact I2C interface supports the standard (100 Kbits/s) clock rate in 7-bit address mode.

Multiple sensor interfaces may be connected to a single I2C bus. The bus address of individual sensor interfaces can be configured by writing desired address value (4 to 127) via the I2C interface to register address 0 with an I2C Write Operation.
