EFB-RC24C41

Alarms, Buzzers, And Sirens Overview

The EFB-RC24C41 is a discontinued audio piezo transducer manufactured by Panasonic Electronic Components. It operates on a single-tone working mode with an external drive input type, utilizing a peak-to-peak signal voltage rated at 10 V and a maximum rated voltage of 30 V. The device produces a sound pressure level of 85 dB at 10 V measured from a distance of 10 cm, with a resonant frequency of 4 kHz. Physically, it features a circular design with a diameter of 24.00 mm (0.945 inches) and a maximum height of 4.80 mm (0.189 inches). The unit supports panel or flange mounting via wire leads and functions within a temperature range of -10°C to 60°C.
