CPS-4059W-1105PM

Alarms, Buzzers, And Sirens Overview

The CPS-4059W-1105PM is a compact, low-profile surface-mount piezoelectric buzzer manufactured by Same Sky. It features a built-in oscillator circuit that generates an audible tone when powered by a DC voltage source. The device operates at a nominal frequency of 2.8 kHz with a sound pressure level of 85 dB at a distance of 10 cm. Designed for space-constrained applications, it utilizes a standard 4-pin configuration and accepts a wide input voltage range from 3.0 V to 12.0 V DC. The unit is housed in a plastic casing with a protective mesh cover.
