57300066

Overview

The WERMA USA Inc. model 57300066 is an internally driven magnetic horn designed for industrial signaling applications. It operates on a continuous tone at a rated voltage of 42 V AC and draws a current of 250 mA. The device produces a sound pressure level of 105 dB measured at the specified voltage. It features screw terminals for electrical connection and includes a 100 cm cable length for installation flexibility. The housing utilizes black and grey coloration, consistent with standard industrial aesthetic requirements.

Feature Summary

• Internally driven magnetic technology for reliable acoustic output
• Continuous tone signal generation capability
• Screw terminal interface for secure wiring connections

Applications

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

Procurement Notes

Verify that the operational environment supports the 42 V AC rating and 250 mA current draw. Confirm compatibility with existing mounting infrastructure for the included 100 cm cable assembly. Ensure the 105 dB acoustic output meets site-specific noise regulations. Cross-reference the black and grey housing finish against facility standards to ensure visual consistency with other installed signaling devices.

Selection Notes

Select this component when a high-decibel continuous tone is required for critical area warnings. The internal drive mechanism simplifies integration by eliminating the need for external drivers. Verify that the 42 V AC supply is available at the installation point. Consider the 100 cm lead length as a constraint or advantage depending on proximity to the control panel relative to alternative models with different cable specifications.

Part Context

This unit belongs to the WERMA USA Inc. range of audible signaling devices. It complements visual indicators by providing distinct auditory feedback for operational states. The product line emphasizes durability and clear signal transmission in noisy industrial environments. Integration with broader automation systems relies on standard electrical interfaces compatible with common PLC outputs.
