The ULCH-09-525-S(M) is a panel mount piezoelectric buzzer from the Floyd Bell Inc AudioLarm II series. It features an internally driven indicator circuit and accepts DC input within a voltage range of 5 to 25 volts. The device operates at a frequency of 2.9 kHz with a sound pressure level of 70 dB at 5V measured at 61 cm. Power consumption ranges from 5 to 25 mA. It utilizes quick connect tabs for termination and is designed for top port location. The unit measures 1.410 inches in diameter and has a maximum installation height of 1.480 inches.
Verify that the specific suffix (M) corresponds to the required termination style, as variations exist within the ULCH-09-525 family. Confirm that the operating environment remains within the specified -20°C to 65°C temperature range. Ensure the application voltage stays within the 5V to 25V DC limits to maintain proper acoustic output and component longevity. Cross-reference the exact part number against official distributor catalogs to confirm current availability and active status.
Select this component when a compact, internally driven piezo buzzer with quick-connect terminals is required. It is suitable for applications needing a 2.9 kHz tone with moderate acoustic output. Consider alternative models if higher decibel levels or different mounting styles are necessary. Verify compatibility with existing panel cutouts given the 35.81 mm diameter specification.
This part belongs to the AudioLarm II series, which provides various panel mount solutions. It shares design characteristics with other ULCH-09-525 variants, differing primarily in termination methods such as wire leads or quick connect tabs. The series is engineered for durability in industrial environments.
The ULCH-09-525-Q(M) serves as a confirmed substitute within the same series, offering identical electrical and acoustic specifications but potentially differing in termination style.
