188PZ22400LFMP

Overview

The DB Products 188PZ22400LFMP is an externally driven piezoelectric transducer designed for alarm and buzzer applications. It operates at a nominal voltage of 12 V with a supply current of 5 mA. The device produces a sound pressure level (SPL) of 90 dB at 12 V measured at a distance of 10 cm. Its operating frequency is 4 kHz, and it utilizes a single-tone action mode. The component is available in bulk packaging.

Feature Summary

• Externally driven piezoelectric design for reliable acoustic signaling
• Single-tone operation mode suitable for standard alarm applications
• Surface mount or through-hole compatible construction

Applications

• Industrial alarm systems
