FSR RX-D4046 150kg

The FSR RX-D4046 150kg is a thin-film force sensitive resistor (FSR) rated for loads up to 150 kg. Its resistance drops as more force is pressed on the sensing area, so a simple voltage divider turns pressure into a voltage that an Arduino, ESP32 or other microcontroller can read on an analog input. It is a good choice for detecting presence, pressure or approximate load in heavy-duty projects.

• Model: RX-D4046
• Force range: up to 150 kg
• Working principle: resistance decreases as the applied force increases
• Output: variable resistance, read through a voltage divider
• Connection: 2 leads, no polarity

FSR RX-D4046 150kg Applications

• Seat, bed and floor-mat occupancy detection
• Load detection where approximate values are enough
• Robot feet, grippers and pressure-sensitive controls
• Interactive installations and STEM projects

What's in the Box

• 1 × FSR RX-D4046 force sensitive resistor

Tip: Connect the FSR between 5 V (or 3.3 V) and an analog pin, with a fixed resistor from that pin to ground; start with 10 kΩ and adjust it for your force range. FSRs give relative force readings, so for accurate weighing use a load cell with an HX711 amplifier instead.
