Flex sensor is a two terminal device. The Flex sensor does not have polarized terminals like diode. So there is no positive and negative.

• Operating  voltage of FLEX SENSOR: 0-5V ( used with a Resistance as divider)

• Can operate on LOW voltages

• Power rating : 0.5Watt (continuous), 1 Watt (peak)

• Life: 1 million

• Operating temperature: -45ºC to +80ºC

• Flat Resistance: 25K Ω

• Resistance Tolerance: ±30%

• Bend Resistance Range: 45K to 125K Ohms(depending on bend)
