11906815

Overview

The Werma 11906815 is an electrical buzzer designed for continuous or slow pulse acoustic signaling. It operates on both 24V AC and 24V DC supply voltages, producing a sound pressure level of 90dB at a distance of 1 meter. The device features a grey housing constructed from PC/ABS materials and measures 49 mm in height with a weight of 45 g. It offers panel mounting capabilities and carries an IP30 protection rating.

Feature Summary

• Supports dual voltage operation for 24V AC and 24V DC systems
• Provides continuous or slow pulse acoustic output modes
• Constructed from durable PC/ABS housing materials

Applications

• Industrial machine status indication
• Control panel alarm signaling
• Factory automation safety alerts

Procurement Notes

Verify the specific acoustic mode requirement (continuous vs. slow pulse) against application needs. Confirm that the IP30 rating meets environmental exposure standards. Ensure the 24V AC/DC input matches existing control circuitry. Check physical dimensions for panel cutout compatibility.

Selection Notes

Select this model when low-profile acoustic signaling is required within control enclosures. The 49 mm height allows for compact installation. Verify that ambient noise levels do not exceed the 90dB output capability. Consider the PC/ABS material properties for chemical resistance if used in harsh industrial environments.

Part Context

This component belongs to the Werma EM series of electrical buzzers. It serves as an audible indicator complementing visual signal towers. The design focuses on reliable performance in standard industrial control panels where space is limited but clear auditory feedback is necessary for operator awareness.
