The PKB5-3A0 MOD Piezo Buzzer is a high-output self-driven audible signalling device designed for industrial equipment, alarm systems, automation controls, security devices, and OEM electronic products. Operating from a 12V DC power supply, this piezoelectric buzzer delivers a powerful 96dB sound output at 30cm, ensuring alarms and status notifications remain clearly audible in demanding environments.
Featuring an integrated oscillator, the PKB5-3A0 MOD generates a single-tone audible signal at 2800Hz, eliminating the need for an external drive circuit. Its low current consumption of only 10mA makes it an energy-efficient solution for continuous or intermittent audible signalling applications.
The buzzer is housed in a durable 41.8mm round black enclosure with flexible lead wire termination, allowing for quick installation in electrical panels, industrial machinery, alarm systems, control cabinets, and custom electronic equipment. Its solid-state piezoelectric construction ensures reliable, maintenance-free operation and long service life.
Whether used in industrial automation, access control, warning systems, or electronic equipment, the PKB5-3A0 MOD provides dependable audible indication with simple installation and excellent reliability.
