CUI Devices has expanded its range of waterproof buzzers with three models carrying an IP rating up to IP68 and featuring SPL up to 95dB at 30cm. This makes the CPT‑1495C‑300, CPT‑1495CI‑300 and CPT‑2521C‑500 suited 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 from ‑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 from ‑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.

The CPT‑1495C‑300, CPT‑1495CI‑300 and CPT‑2521C‑500 are available immediately through distribution with prices starting at $2.39 each in 1,000 unit quantities.
