Waterproof buzzers for high-moisture environments

CUI’s Components Group has announced new additions to its range of waterproof buzzers. The three new models carry an Ingress Protection rating up to IP68 and feature sound pressure levels (SPL) up to 95dB at 30cm, suiting them for a range of industrial and outdoor applications where moisture and other environmental contaminants are a concern.

The CPT 1495C 300 and CPT 1495CI 300 are piezo transducer buzzers housed in a 14mm diameter package with a height of 10mm. Specified with a rated voltage of 30V and a rated frequency of 4.25kHz, both waterproof buzzers are externally driven and feature an IP67 rating, SPL of 84dB at 10cm and an operating temperature range of 30 to 85°C. The CPT 1495C 300 mounts via wire leads while the CPT 1495CI 300 is wave solder compatible for high-volume production.

For applications where design for continuous immersion below 1m is needed, the CPT 2521C 500 offers an IP68 rating and an operating temperature range of 30 to 85°C. Housed in a 25mm diameter package with a height of 21mm, this externally driven piezo transducer buzzer features wire leads and an SPL of 95dB at 30cm. The series also features a maximum operating voltage of 50V and a rated frequency of 3.7kHz.
