{"title":"RP-L-400 Thin Film Pressure Sensor","handle":"rp-l-400-thin-film-pressure-sensor","url":"/products/rp-l-400-thin-film-pressure-sensor","description":"The RP-L-400 is a long, flexible thin-film pressure sensor with a 400 mm active length. It detects both static and dynamic pressure by converting applied force into a variable resistance — resistance decreases as pressure increases. The ultra-thin construction (0.35 mm) and fast response time make it suitable for integration into smart textiles, medical devices, bed monitoring systems, and human-interface applications.\n\nThe sensor consists of two layers: an upper film with a pressure-sensitive conductive layer and a lower film with a printed circuit. When force is applied to the active area, the layers make contact and complete the circuit, producing a measurable resistance change proportional to the applied pressure.\n\nKey Features\n\n\n400 mm Flexible Sensing Length – Long active area for distributed pressure detection\n\nUltra-Thin – 0.35 mm total thickness\n\nWide Pressure Range – 20 g to 10 kg (or greater)\n\nFast Response – < 10 ms response time\n\nLow Trigger Force – Activates at < 20 g\n\nLong Lifespan – > 1 million actuations\n\nNo EMI/ESD Generation – Safe for sensitive electronics\n\n\nSpecifications\n\n\nThickness – 0.35 mm\n\nTrigger Force – < 20 g (default resistance < 200 kΩ)\n\nPressure Range – 20 g to 10 kg+\n\nInitial Resistance – > 10 MΩ (no load)\n\nActivation Time – < 0.01 s\n\nResponse Time – < 10 ms\n\nFrequency – Static and dynamic (up to 10 Hz)\n\nDrift – < 5 % (2.5 kg, 24 h static load)\n\nHysteresis – ±10 % at 1000 g\n\nLifespan – > 1 million cycles\n\nOperating Temperature – −40 °C to +85 °C\n\n\nIdeal For\n\nBed and seat occupancy monitoring\nSmart textiles and wearable pressure sensing\nMedical device interfaces\nPressure-sensitive switches and triggers\n\n\nPackage Contents\n\n1× RP-L-400 thin-film pressure sensor\n\n\nResources\n\nDFRobot Product Wiki\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":4900,"title":"Default Title","sku":"DF-SEN0299","price":18.47,"on_sale":false,"in_stock":true,"available_quantity":93,"option1":"Default Title"}]}
