ISSR - Model ISU200-16.7TRBJ -200kHz High-Sensitivity Ultrasonic Transducer Sensor for Double Sheet & Distance Detection
· With a center frequency up to 200kHz (±20kHz), short wavelength, and strong directivity, it significantly improves the detection accuracy of small objects or thin materials · Utilizing a robust waterproof and sealed structure, it can operate stably in a wide temperature range of -40°C to +70°C, unaffected by humidity, dust, and harsh industrial environments · The optimized piezoelectric ceramic structure controls the residual oscillation time to ≤270μs, greatly reducing the detection dead zone and achieving high-speed response at close range · Echo sensitivity ≥800mV (measured against a Φ25mm PVC pipe at 10cm), combined with a maximum drive voltage of up to 400Vp-p, ensures a strong and stable signal · The compact Ø16.7mm package design integrates transmission and reception functions, facilitating easy installation, lightweight design, and system integration
The ISU200-16.7TRBJ is a 200kHz high-frequency Ultrasonic Distance transducer designed specifically for high-precision industrial automation applications. Engineered as an advanced piezoelectric transducer with a hermetically sealed, integrated transceiver structure, this product perfectly addresses the limitations of traditional low-frequency sensors in short-range detection and complex environments. With its high operating frequency of 200kHz, the sensor features an extremely short wavelength and superior directivity. This not only significantly enhances measurement resolution but also establishes it as an ideal Double Sheet Detection transducer, capable of accurately identifying overlapping layers of paper, film, or metal sheets.
In terms of reliability, the sensor's industrial-grade waterproof housing ensures a high-sensitivity echo output of ≥800mV across an extreme temperature range of -40°C to +70°C, maintaining an excellent Signal-to-Noise Ratio (SNR). The ringing time is strictly controlled to be ≤270μs, resulting in a minimal blind zone and rapid response speed that is highly suitable for high-speed production lines. Because of these precise acoustic characteristics, it performs exceptionally well as an Ultrasonic Level Sensor probe in challenging tanks or silos. Whether applied in fast-paced logistics sorting, double sheet control for printing machinery, or functioning as a reliable Ultrasonic level monitoring transducer for liquid and solid materials, the ISU200-16.7TRBJ provides a low-cost, high-performance sensing solution characterized by its simple structure and dependable operation.
