57005258

Overview

The WERMA USA Inc. model 57005258 is an electric loud signal horn belonging to the 570 series. It operates on a 230V DC supply and produces a continuous tone with a sound pressure level of 108 dB measured at a distance of one meter. The device features a gray ABS housing and provides IP55 ingress protection against dust and water jets. It utilizes screw terminals for electrical connection and functions within an operating temperature range of -20°C to 60°C.

Feature Summary

• Produces a continuous acoustic signal using electromechanical technology
• Constructed with a durable gray ABS housing material
• Designed for panel mounting applications

Applications

• Industrial machinery status indication
• Factory floor safety warnings
• Process control alarm signaling

Procurement Notes

Verify that the installed power supply provides stable 230V DC output, as this unit is not compatible with AC voltages. Confirm that the mounting location allows for adequate sound propagation without obstruction. Ensure the ambient temperature remains within the specified -20°C to 60°C operational limits to maintain performance integrity and component longevity during continuous use.

Selection Notes

Select this specific model when a high-decibel continuous tone is required for long-distance auditory alerts in industrial environments. The 230V DC specification distinguishes it from standard 24V or AC variants. Consider the IP55 rating for areas exposed to splashing water or dust, though it is not suitable for high-pressure washdowns requiring higher IP ratings.

Part Context

This component is part of the Werma 570 series of signallers, which are designed for industrial automation and process monitoring. The series offers various acoustic options including horns and sirens. This particular item represents the membrane siren variant within the lineup, providing robust audible notification capabilities for critical system alerts.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. When replacing, ensure the new unit matches the 230V DC voltage requirement and maintains equivalent decibel output levels. Verify that the physical dimensions and terminal types are compatible with existing mounting panels and wiring configurations.

FAQ

Is the 57005258 compatible with AC power supplies?

No, this unit is strictly designed for 230V DC operation and will not function correctly with AC voltage.

What type of electrical connection does this signal horn use?
