YZC-161B 5kg Aluminum Load Cell Sensor for Human Scale and Weight Measurement

This YZC-161B load cell is a 5kg half-bridge strain-gauge sensor designed for accurate weight and force measurement in compact digital scales. The sensor converts mechanical load into a proportional analog voltage signal, with a rated output of 1.0 ±0.1mV/V, nonlinearity of 0.08%F.S, and repeatability of 0.05%F.S. Its three-wire interface—red for supply, black for ground, and white for signal—simplifies wiring to HX711-type amplifiers and microcontroller ADCs. The IP65-rated body protects the internal strain gauges from dust and water splashes, making this weight sensor suitable for kitchen scales, baby scales, and light industrial weighing tasks. Operating from a recommended 5V DC excitation (8V maximum), the sensor maintains stable performance across a temperature range of -20°C to +65°C. The half-bridge configuration allows multiple units to be combined for higher-capacity platforms, while the compact aluminum body fits space-constrained enclosures. Whether used in a DIY Arduino scale or a commercial platform scale, this 5kg load cell offers a practical balance of precision, durability, and straightforward analog interfacing.
