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.
