Description:

This is a flexible bend sensor with 2.2" in length  from US, patented technology by Spectra Symbol. As the sensor is flexed, the resistance across the sensor increases. This can be tested with multimeter. The resistance of the flex sensor changes when the metal pads are on the outside of the bend (text on inside of bend).

Specification:

• Life cycle: >1 million
• Height: 0.43mm (0.017")
• Temperature Range: -35 degree C to +80 degree C
• Flat Resistance: 25K Ohms
• Resistance Tolerance: ±30%
• Bend Resistance Range: 45K to 125K Ohms (depends on bend radius)
• Power Rating: 0.50 Watts continuous. 1 Watt Peak.
