1. Bending sensor. The degree of bending of the sensor can be translated into a change in resistance value. The more the bend, the higher the resistance. This sensor can be used to make an energy glove 2. Bending direction: the side with the word is the inner side when bending. Avoid bending the end pin portion (i.e. the part that is not bent) during use, as damage may result : Model: Flex Sensor 4.5inch / 2.2 inch Technical Specifications Straight Resistor: 25K ohms Resistance Tolerance: +30% Bend Resistance change: 60K-110K ohms Rated Power: 0.5 Watt Peak Power: 1 Watt Bending life: Greater than1 million times Working temperature: 35C~+80C Interface type: 2-pin metal pins (0.1 pitch) Torque sensor, for electronic gloves. When the sensor's metal bends outward, the resistance of the sensor changes and the bend can be detected. Non-bending state resistance: -9000 ohms 90 degree bending resistance: 14000 ohms 180 degree bending resistance: 22000 ohms Principle: Current Sensor Application: pressure sensor Type: Vibration Sensor Output: Analog Sensor size: 11 x 1 x 1cm / 7.5 x 1 x 1cm Material: ABS colour: yellow Package Contents: 1 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.
