57400070

Overview

The Werma 57400070 is a wall-mountable signal horn designed for industrial environments. It operates on an AC/DC voltage range of 10-48V and draws a rated operational current of 210mA with a maximum inrush current of 650mA. The device emits a continuous tone at 110Hz with a sound pressure level of 108dB measured at 24V from a distance of 1 meter. It features screw terminals for connection and carries IP65 protection classification.

Feature Summary

• Generates a continuous acoustic signal using internally driven magnetic technology
• Provides high-intensity sound output suitable for noisy industrial settings
• Supports flexible power supply integration via broad AC/DC voltage compatibility

Applications

• Industrial machinery status indication
• Factory floor safety alarms
• Process control auditory signaling

Procurement Notes

Verify the specific voltage rating required for your application against the 10-48V AC/DC input specification. Confirm that the mounting location meets the IP65 environmental protection requirements. Ensure the installation environment does not exceed the electrical limits defined in the official datasheet to maintain safe operation and certification validity.

Selection Notes

Select this model when a continuous tone signal is required rather than a siren pattern. It is appropriate for applications needing moderate sound levels up to 108dB. Consider the physical dimensions and wall-mount configuration during system design. Verify that the operating temperature range aligns with the specific site conditions before finalizing the component choice.

Part Context

This unit belongs to the Werma 574 series of electronic sounders. The series includes various horn and siren configurations designed for visual and auditory signaling systems. These components are engineered for durability and reliability in demanding manufacturing and automation sectors, offering standardized mounting and connection interfaces.

Replacement Considerations

Check for compatible Werma series replacements if the exact part is unavailable. Ensure any substitute maintains the same voltage range, sound output characteristics, and mounting specifications to guarantee seamless integration into existing infrastructure without requiring structural modifications.
