10900075

Overview

The Werma 10900075 is an internally driven electromagnetic buzzer designed for audible signaling. It operates on a rated voltage of 24 V AC/DC with a current consumption of 25 mA and an inrush current of 200 mA. The device produces a continuous tone at a frequency of 2.1 kHz, achieving a sound pressure level of 80 dB at a distance of 1 meter. It features a compact 22 mm diameter housing constructed from ABS/polycarbonate materials in black. The unit provides IP65 protection against dust and water jets and utilizes screw terminals for connection, supporting a maximum wire cross-section of 1.50 mm² (16 AWG).

Feature Summary

• Internally driven electromagnetic mechanism for reliable audible alerts.
• Continuous tone output optimized for industrial alarm environments.
• Robust IP65-rated enclosure suitable for demanding operational conditions.

Applications

• Industrial machinery status indication.
• Control panel audible alarms.
• Safety system warning signals.

Procurement Notes

Verify the specific acoustic requirements, ensuring the 80 dB output at 1 meter meets the ambient noise levels of the installation site. Confirm that the 24 V AC/DC operating voltage aligns with the existing control circuitry. Check that the screw terminal connections are compatible with the available wiring gauge, noting the maximum support of 1.50 mm². Ensure the IP65 rating satisfies the environmental exposure standards of the intended mounting location.

Selection Notes

Select this model when a compact, internally driven audible signal is required within a 24 V system. The 22 mm form factor allows for integration into space-constrained panels. Consider the continuous tone characteristic for persistent alert scenarios. Evaluate the IP65 rating against potential exposure to dust or washdown procedures. Compare the 80 dB output capability against background noise levels to ensure adequate audibility without requiring higher-decibel alternatives.
