Eaton M22-LH-Y Alarm Light Indicator, 250 V, Yellow

The Eaton M22-LH-Y is a professional-grade alarm light indicator engineered for integration into industrial control panels, automation systems, and electrical distribution boards. This component provides a reliable visual signal through its bright yellow illumination, allowing operators to monitor machine status, safety alerts, or process conditions effectively. Designed for durability, it maintains consistent performance in challenging industrial environments, ensuring that critical information is communicated clearly to personnel.

Advantages

The primary benefit of this indicator is its robust construction, which allows it to withstand significant temperature fluctuations ranging from -25 to 70 °C. Its standardized design ensures seamless compatibility with common 22 mm mounting holes found in most industrial enclosures. By utilizing a 250 V AC input, it integrates easily into standard control circuits without the need for complex voltage conversion, providing a straightforward and dependable solution for status signaling in demanding operational settings.

Suitable for

• Industrial control panels and automation cabinets
• Machine status monitoring and diagnostic systems
• Safety alert signaling in electrical installations
• Process control environments requiring clear visual feedback

This indicator may not be suitable for low-voltage DC applications unless the specific electrical circuit is compatible with the rated voltage requirements. Furthermore, it is not intended for outdoor use without an appropriate protective enclosure that meets the necessary ingress protection standards for the specific environment.

Key specifications

• Illumination color: Yellow
• Rated operating voltage: 250 V AC
• Mounting diameter: 22 mm
• Operating temperature range: -25 to 70 °C

To install the Eaton M22-LH-Y, ensure the control panel is de-energized to maintain safety. Insert the indicator into a standard 22 mm mounting hole and secure it firmly using the provided locking mechanism. Connect the electrical leads to the terminals according to the wiring diagram of your control system, ensuring that the voltage supply matches the 250 V AC rating. Once installed, verify the connection and perform a functional test to ensure the light illuminates correctly when the signal is triggered.

What to consider before purchase

• Verify that your control system provides the required 250 V AC power supply
• Ensure the mounting panel has a standard 22 mm aperture
• Confirm that the yellow color meets your specific safety or signaling standards
• Check the environmental conditions to ensure they fall within the specified temperature range

For optimal longevity and performance, ensure that the indicator is installed in a location protected from direct mechanical impact and excessive vibration. Regularly inspect the lens for cleanliness to maintain maximum visibility of the light signal.
