The Leuze A7-V1-BZ2-S Tower Light Acoustic Element (Order Code: 50138151) is a specialized acoustic signaling module belonging to the premier A7 Series (Advanced Series) engineered by Leuze electronic (Germany). Designed to integrate seamlessly onto the top of modular optical LED stacklight columns, it provides high-impact auditory alarms that instantly notify machine operators of critical process faults, production interruptions, or hazardous operating conditions, even within high-noise manufacturing facilities.

The acoustic buzzer produces a distinct, continuous tone with an impressive sound pressure rating of up to 105 dB, ensuring unambiguous alert propagation across expansive factory floors. A major engineering advantage of the A7-V1-BZ2-S is its integrated 225° rotary potentiometer located beneath the module, giving plant engineers the flexibility to modulate the sound output volume smoothly to match diverse operational soundscapes—from quiet testing laboratories and cleanrooms to heavy metal-cutting machine shops with significant ambient background noise.

Constructed with an industrial standard Ø70 mm cylindrical footprint and a compact length of 50 mm, the buzzer element features a rugged, impact-resistant industrial thermoplastic enclosure in matte black finish. The module utilizes an ergonomic quick-mount Bayonet fastening system, allowing operators to securely attach or detach the acoustic head in seconds with a simple twist without requiring hand tools. Electrical contact is established via high-reliability, misconnection-proof contact pins, actuated directly via 24 V DC (PNP positive logic) with a remarkably low power consumption of maximum 30 mA.

Engineered to endure severe industrial environments, the A7-V1-BZ2-S boasts an outstanding IP66 environmental ingress protection rating (conforming to EN 60529), effectively shielding internal acoustic components against heavy airborne dust and high-pressure water washdowns. Operating reliably across a broad temperature span from -10°C to +60°C and certified to international CE and CSA directives, this acoustic tower light element represents an indispensable safety signaling component for CNC machining equipment, plastic injection presses, high-speed automated packaging cells, and robotic transfer jigs.
