Bending sensor. The degree of bending of the sensor can be converted into a change in resistance value. The larger the bending, the higher the resistance Note: Bending direction: The side with the word is the inner side when bent. Avoid bending the end pin portion (ie, the non-bending sensing portion) during use, otherwise it is likely to cause damage. Straight resistance: 25K ohms Resistance tolerance: +30% Bending resistance change: 60K-110K ohm Rated power: 0.5 watt Peak power:1 watt Bending life: Greater than 1 million times Working temperature:-35°C-+80 ° C Interface type:2-Pin metal pin (pitch 0.1inch) Colour:As Shown Material:Mixed Materials Size:2.2 inch Package Contents: 4 x Flex Sensor Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
