Amphenol TSW-10 Turbidity Sensor Phototransistor Output

The Amphenol Advanced Sensors Thermometrics TSW-10 Turbidity Sensor is a compact 5 V DC optical module that measures turbidity in wash water by transmitting light from an LED source to a phototransistor receiver and sensing how much light passes through the sample. Designed for use in washing machines and dishwashers, it provides a phototransistor output and is powered between VCC and ground, with the LED and receiver arranged to quantify turbidity for appliance control decisions. Electrical specs include a rated current up to 30 mA, a 5 V DC supply, and an insulation resistance of at least 100 MΩ at 500 V DC, with the LED forward voltage around 1.3 V (1.3 V ± 20%). The sensor operates from −30°C to 80°C and can be stored from −10°C to 80°C. Turbidity level calibration uses Master NTU standard liquids, testing light transmission at 0 NTU and 1000 NTU to map turbidity levels, which supports appliance logic that adjusts wash cycles based on water clarity. The TSW-10 is listed under Amphenol Advanced Sensors’ Thermometrics line as the Turbidity Sensor Phototransistor Output, with the part number TSW-10 and applications centered on detecting the turbidity degree of water in household appliances.
