10901075

Overview

The WERMA USA Inc. model 10901075 is an internally driven magnetic audible alarm buzzer designed for panel mounting applications. It operates on a 24 VAC/VDC supply and features a pulse tone output with a sound pressure level of 80 dB at 1 meter. The unit has a compact diameter of 22 mm, consumes 25 mA of current, and weighs 59 grams. Constructed with an ABS/polycarbonate housing in black, it provides IP65 protection against dust and water jets. Operating temperatures range from -20°C to +50°C.

Feature Summary

• Internally driven magnetic technology for reliable pulse tone generation
• Compact 22 mm diameter design suitable for space-constrained panels
• High sound pressure level of 80 dB ensures audibility in noisy environments
• Dual voltage compatibility supporting both AC and DC power sources

Applications

• Industrial machinery status indication
• Factory automation safety alerts
• Control panel warning systems
• Transportation vehicle signaling

Procurement Notes

Verify the specific ordering suffix matches the required voltage rating (24VAC/DC) and tone type (pulse). Confirm that the panel cutout dimension aligns with the 22 mm diameter specification. Ensure the installation environment meets the IP65 protection requirements and temperature limits of -20°C to +50°C. Cross-reference the manufacturer part number 109.010.75 with distributor listings to confirm availability and authenticity.

Selection Notes

Select this component when a low-profile, high-decibel audible signal is required for panel-mounted installations. The dual-voltage capability simplifies integration into systems using either AC or DC control circuits. Consider the 22 mm footprint for tight enclosure layouts. Verify that the pulse tone frequency of 2.1 kHz meets the specific auditory alert requirements of the application compared to continuous tone alternatives.

Part Context

This buzzer belongs to the Werma EM series of electric buzzers, which are engineered for industrial signaling tasks. The series offers various voltage options and tone configurations to suit different operational needs. The 10901075 variant specifically addresses the need for a robust, compact alarm device compatible with standard 24V control systems commonly found in modern industrial automation setups.

Replacement Considerations

Direct substitutes within the Werma portfolio include other EM series buzzers with identical mechanical dimensions but differing electrical characteristics. Verify that any replacement maintains the 22 mm mounting diameter and IP65 rating. Check if the alternative part supports the same 24VAC/DC input and pulse tone requirement to ensure functional equivalence without redesigning the panel cutout.
