Buzzers Expansion

In the ever-evolving world of acoustic signaling devices, PUI Audio stands at the forefront, introducing five new buzzers – two indicators and three transducers, ranging from 12mm to 55mm, including one surface mount transducer, bring together high sound pressure levels (SPL), and temperature resilience to cater to a diverse range of applications. Buzzers are essential for providing immediate auditory feedback or alerts in a wide range of industries and everyday situations. Key application scenarios include alerts for household appliances, security systems, user-input confirmation, automotive safety warnings, healthcare equipment, industrial machine diagnostics, and consumer electronic devices.

New Audio Indicators

AI-3232-TWF-LW160

Is a internally driven piezoelectric indicator that operates on 12V DC. Its true innovation lies in its unique drive IC and material composition. The resonant effect, combined with a precisely designed chamber, elevates its sound output to an impressive 116dB! This makes it the perfect choice for applications where an exceptionally loud and attention-grabbing signal is required. Notably, this component is not only RoHS and REACH compliant but also meets qualifications for POPS (Persistent Organic Pollutants), TSCA (Toxic Substance Control Act), and CA PROP65 (California Proposition), aligning with the most stringent environmental and safety standards.

AI-1223-TWT-5V-7

For applications requiring a smaller form factor and internal drive capability, the 12mm Buzzer AI-1223-TWT-5V-7 stands out as a versatile choice. Operating on 5V DC, this audio buzzer emits a sound output of 90dB and features a wide temperature range up to 105°C. Its robust design ensures reliability in challenging environments, and it can function as an indicator in various settings.

SMT-1227-T A

12mm surface mount piezoelectric transducer engineered for very high-temperature environments up to 120°C. Operating on a 3Vp-p external drive and drawing only 5mA, this compact buzzer boasts an impressive SPL and remarkably short response time. Its ability to withstand elevated temperatures makes it ideal for applications where reliability under harsh conditions is essential.

AT-3033-TT-R

Measuring 30mm in width and 7.5mm in height, this compact Piezo transducer offers a high 90dB SPL, making it versatile for a wide range of applications. With a rated voltage of 10 Vp-p, you can trust that it is engineered for optimum performance even in harsh environments up to 85°C. Drawing just 10mA at its rated voltage, it is not only powerful but also energy-efficient, making it ideal for applications where power consumption is a concern.

AT-5532-TF-HT-LW190

With a maximum voltage of 60 Vp-p for 10 minutes, the piezo transducer AT-5532-TF-HT-LW190 delivers an output SPL of 110dB and performs reliably within temperatures ranging from -40°C to 85°C. The preinstalled lead wires simplify installation in almost any environment. Additionally, this buzzer is IP66/67 rated according to IEC 60529 Edition 2.2.2013.
