It detects force across a 20g to 6kg range, with resistance changing linearly as pressure is applied for easier interpretation in control systems.The thin 0.45 mm film construction suits compact mechanical designs, robotics, tactile interfaces and embedded pressure pads. It is rated for operation from -40 °C to +120 °C, making it useful around heated surfaces, machinery and automotive applications where ordinary flexible sensors may struggle.The sensor supports direct soldering for a more permanent connection than plug-in membrane sensor connectors. The supplier also shows a typical voltage-divider sampling circuit using a series 2KΩ resistor, and the shipping list includes one Circular Flexible Potentiometer.Features:High-temperature stability: Maintains stable operation in temperatures ranging from -40°C to +120°C.Precision linear output: Resistance changes linearly with applied pressure to simplify data interpretation.Wide force detection: Accurately perceives pressures as light as 20g and as heavy as 6kg.Rapid response: Activation time of less than 0.01 seconds and response latency under 1ms.Mechanical durability: Tested to withstand over 10 million mechanical presses at 1kg force.Ultra-thin integration: Measures only 0.45mm in thickness for compact spaces.Direct soldering: Allows permanent, secure wire connections for vibrating or mobile applications.Specifications:Thickness: 0.45 mmActuation Force: 20gPressure Range: 20g ~ 6 kgResistance at Actuation (20g): ＜ 200 kΩResistance at Full Scale (6kg): ＜ 1 kΩResponse Time: ＜ 1 msOperating Temperature: -40 °C ~ +120 °CDurability: > 10 million cycles (1 Kg force, flexible press)Activation Time: ＜ 0.01 SSuitable uses include robotic gripper force feedback, tactile robot skins, seat occupancy sensing, heated surface monitoring, safety switches and pressure-sensitive touch panels.","vendor":"DFRobot","product_type":"Force Sensor","in_stock":true,"options":[],"variants":[{"id":15968,"title":"Default Title","sku":"DF-SEN0684","mpn":"SEN0684","price":9.6,"on_sale":false,"in_stock":true,"available_quantity":287}]}
