Sensor products for wholesale sourcing span a broad range of physical measurement principles: temperature sensors — thermocouples (Types J, K, T, E, N, R, S for high-temperature industrial applications), Pt100/Pt1000 RTDs (precision resistance temperature detectors, -200°C to +600°C), NTC thermistors (compact negative temperature coefficient sensors, -40°C to +125°C, used in HVAC and consumer electronics), IC temperature sensors (LM35, DS18B20, TMP117 — direct digital output, simplified measurement, used in PCB-level temperature monitoring); pressure sensors — piezoresistive MEMS sensors (gauge, absolute, differential — 0–10 mbar to 0–1000 bar range, I²C/SPI or 4–20mA/0–10V output), capacitive pressure sensors (for low differential pressures, high accuracy), piezoelectric sensors (for dynamic pressure measurement); proximity and position sensors — inductive proximity switches (for metal target detection), capacitive proximity switches (for liquid level and non-metallic targets), photoelectric sensors (through-beam, retroreflective, diffuse), magnetic Hall effect sensors, and LVDT/RVDT displacement transducers; motion and inertial sensors — accelerometers (MEMS, ±2g to ±400g), gyroscopes (MEMS, degrees/second), IMU modules (combined accelerometer + gyroscope ± magnetometer); and gas and chemical sensors — O2, CO, CO2 (NDIR), VOC (electrochemical and photoionisation), H2, and combustible gas sensors for industrial safety and air quality monitoring.
