VAZ-BUZZER/LT-RD

Overview

The VAZ-BUZZER/LT-RD is an acoustic signaling device from the Pepperl+Fuchs VAS series, designed for industrial automation environments. It features a red LED status indicator and generates audible alerts to signal machine states or faults. The unit operates on a DC voltage supply of 24 V with a current consumption of approximately 100 mA. It provides a sound pressure level of 85 dB at a distance of one meter. The housing is constructed from polycarbonate, offering protection ratings of IP67 and IP69K to withstand harsh conditions including high-pressure washdowns. The device includes a mounting bracket for secure installation.

Feature Summary

• Integrated red LED visual indicator for immediate status visibility
• Acoustic alarm generation with defined sound pressure output
• Robust polycarbonate housing resistant to industrial chemicals
• High ingress protection rating suitable for hygienic and washdown areas

Applications

• Machine fault signaling in automated production lines
• Status indication for packaging and filling machinery
• Safety alert systems in food and beverage processing plants
• Warning signals in cleanroom environments requiring frequent washing

Procurement Notes

Verify that the specific order suffix matches the required voltage and connector configuration. Confirm that the IP67/IP69K rating aligns with the cleaning protocols of the target application environment. Ensure the mounting hardware is compatible with the installation surface. Check for any regional certification requirements such as UL or CE marking if applicable to the facility standards. Validate the operating temperature range against the ambient conditions of the deployment site.

Selection Notes

Select this model when both visual and audible signaling are required within a single compact unit. The red LED color is standard for warning or fault states. Consider the 85 dB output level relative to background noise levels in the installation area. The polycarbonate material offers good resistance to common industrial cleaners but should be checked against specific aggressive solvents used in the process. The 24 V DC supply is typical for standard PLC I/O outputs.

Part Context

This component belongs to the VAS series of acoustic and optical signaling devices by Pepperl+Fuchs. These devices are engineered for integration into industrial control panels and machine frames. The series emphasizes durability and clear signaling in demanding environments. The VAZ-BUZZER/LT-RD specifically combines buzzer functionality with a red light, providing a dual-mode alert system for operators.

Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Cross-reference with other models in the VAS series for similar form factors or signaling capabilities. Verify electrical compatibility before substituting with generic industrial buzzers.
