Perfect partner for PMUTs – the SECO ultrasonic transducer SC517

04.09.2023 | innovations, Products

Perfect partner for PMUTs – excellent for combination with high-sensitivity PMUTs is our new, high-performance 175 kHz mulit-use transducer SC517.

After revision of the matching material design, the SC517 is mainly characterized by a strong echo signal and excellent performance in a working range between 0.1 and 1 meter. In addition to its comparatively long range, solid sheet metal shielding design and cost-effective construction, the SC517 is the perfect partner for PMUTs. PMUTs (piezoelectric micromechanical ultrasonic transducers) are available on the world market for several years. They are – compared to other ultrasonic sensors – weak transmitters but highly sensitive receivers. Thus, the idea for a combined ultrasonic sensor system was born: the SECO ultrasonic transducer SC517 as transmitter together with a highly sensitive PMUT as receiver.

We would be happy to customize our SC517 to your specific application.

Perfect partner for PMUTs - SC517 ultrasonic transducer

SC517 – High performer from our innovative, redesigned SC5X series:

The SC5X series presents our single transducer in a revised design and with even better performance. Single transducers from SECO Sensor combine the comparatively long range of ultrasonic transducers with the fast repetition rate of pulse transducers. This makes them universally applicable products that can be used to construct industrial sensors for a wide range of measuring tasks. SC5X ultrasonic transducers are our next-generation single transducers. Depending on their size, they operate in a range from 80 to 400 kHz. They also have the usual high echo voltage of the single transducers. Thanks to their optimized design, they score points with even shorter settling and decay times. Thus they enable higher repetition rates – for more efficiency in your production!

Details of the PMUT:

PMUTs (Piezoelectric Micromachined Ultrasonic Transducers) are miniaturized ultrasonic transducers based on piezoelectric effects. Compared to conventional ultrasonic transducers, PMUTs offer higher integration capability and lower power consumption. This makes them ideal for portable and compact applications. They consist of thin piezoelectric layers fabricated on silicon substrates. PMUTs are used in numerous industrial applications where they enable precise measurement and imaging on a small scale. Their small size and efficiency in particular make them a key technology in modern ultrasound technology.
