14-810.902

Overview

The EAO 14-810.902 is a flush-mount, internally driven transducer buzzer designed for industrial audio indication. It operates on a continuous 24 Vdc supply with a resonant frequency of 2.8 kHz and draws 25 mA current. The unit produces a sound pressure level of 95 dBA. Mechanically, it features a round front dimension of Ø 29 mm with a mounting cut-out of Ø 22.3 mm. The housing utilizes anodized aluminum or nickel-plated brass, offering IP65 ingress protection on the front face according to DIN EN 60529 standards. Termination is achieved via solder tabs measuring 2.8 x 0.5 mm.

Feature Summary

• Internally driven transducer design requiring only DC voltage input
• Robust metal construction with IP65 front protection rating
• Flush-mount configuration with standardized circular dimensions
• Solder tab termination suitable for PCB integration

Applications

• Industrial control panel status indication
• Machine tool alarm signaling systems
• Heavy equipment operator feedback interfaces
• Automated manufacturing station alerts

Procurement Notes

Verify that the specific order matches the 24 Vdc electrical requirement and 2.8 kHz acoustic output. Confirm the mechanical finish preference, as sources indicate variations between anodized aluminum and nickel-plated brass housings. Ensure the installation environment supports the specified operating temperature range of -25°C to 55°C. Check that the PCB layout accommodates the 2.8 x 0.5 mm solder tab dimensions for proper termination.

Selection Notes

Select this component when a high-intensity 95 dBA audible alert is required in harsh environments. The IP65 rating makes it suitable for washdown areas or dusty industrial settings. Choose this model over electronic buzzers if internal driving circuitry simplification is desired. Ensure the 24 Vdc system voltage aligns with existing control power supplies before implementation.

Part Context

This part belongs to the EAO 14 series of actuators and indicators. The series offers various actuation types including pushbuttons and selector switches. The 14-810.902 specifically addresses the audio notification segment within this modular industrial hardware family, providing standardized mounting compatibility with other 14-series components.

Replacement Considerations
