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.
