11948315

Overview

The Werma 11948315 is an internally driven magnetic buzzer designed for panel mounting. It operates on a 24 V DC supply with a current consumption of 20 mA. The device produces a continuous tone at a frequency of 2.4 kHz and achieves a sound pressure level of 90 dB when measured at a distance of 24 inches (100 cm). It features a protection category of IP65, ensuring resistance to dust and water jets. The unit utilizes a connector interface for electrical connection.

Feature Summary

• Internally driven magnetic sounder mechanism
• Continuous tone generation capability
• IP65 rated enclosure for environmental protection

Applications

• Industrial alarm systems
• Machine status signaling
• Safety warning devices

Procurement Notes

Verify the specific acoustic output requirements against the 90 dB specification at 100 cm distance. Confirm that the 24 V DC operating voltage matches the control circuit. Ensure the panel mounting hole dimensions accommodate the physical diameter of the unit. Check that the connector type aligns with existing wiring harnesses.

Selection Notes

Select this model where a compact, high-decibel audible signal is required in protected environments. The internal drive simplifies wiring by eliminating external drivers. Consider the IP65 rating for areas exposed to washdown or dusty conditions. Verify compatibility with 24 V DC control panels.
