30mm Industrial Continuous Buzzer

This electronic buzzer has a body diameter of 30mm (1.2 inch) and overall dimensions of 47 x 33 x 25mm (1.85 x 1.3 x 1.0 inch). It weighs only 11g and features a durable white plastic housing. Rated for DC 3–24V operation with current draw under 12mA, it delivers sound pressure exceeding 95dB. The operating temperature range is -20°C to +45°C. Mounting is simplified with a 3.5mm diameter hole and 38mm hole spacing. Includes 11cm (4.3 inch) black and red lead wires for easy connection. Designed for reliable continuous-tone signalling in industrial control panels, machinery alerts, and automation systems. Its wide voltage compatibility eliminates the need for additional regulators in mixed-voltage installations. The compact size and lightweight construction allow integration into space-constrained enclosures without adding mechanical load. Suitable for indoor industrial environments where consistent audio feedback is required — such as status indication on PLC cabinets, safety interlock warnings, or machine cycle completion signals.
