Product information

Description

The PATLITE LR4-E-B is a fixed blue LED alarm light designed for 24V DC operation, offering a compact form factor with a width of 40 mm. Its bright blue LED provides distinct visual signalling for industrial and commercial environments where clear, non-flashing indication is needed. RoHS certification confirms compliance with restrictions on hazardous substances, making the unit suitable for installations that require environmental standards adherence.

Advantages

The unit combines low power consumption with high luminous efficiency typical of LED technology, delivering reliable, long-lasting visual alerts without the heat and maintenance requirements of incandescent lamps. Its compact 40 mm width allows flexible mounting in confined panels or equipment housings. Designed for 24V DC systems, the LR4-E-B integrates smoothly into existing control circuits and signalling lines. RoHS compliance reduces environmental and disposal concerns for regulated installations.

Suitable for

Machine status indication on factory equipment and control panels
Visual alarms in production lines and process control systems
Notification lights in cabinets, enclosures, or compact assemblies
Signal marking in laboratories, testing benches, and service areas

Key specifications

Light colour: blue
Light source: LED
Rated voltage: 24V DC
Mounting width: 40 mm (compact profile)
Compliance: RoHS certified
Operation mode: fixed (non-flashing) indication

How to use

Install the LR4-E-B in a suitable panel cut-out or mounting location that supports its 40 mm width. Connect the positive and negative leads to a stable 24V DC supply following standard electrical safety practices and local wiring regulations. Verify polarity and secure wiring to prevent vibration-related loosening. After power-up, the blue LED provides continuous visual indication; no configuration is required for fixed-operation models.

Usage recommendations

For optimal visibility, mount the indicator at eye level relative to the operator work area and avoid obstructions that can block the light. Ensure the supply voltage is regulated and within the specified 24V DC range to maintain LED longevity. Use the LR4-E-B in environments consistent with its protection and installation specifications, and combine with audible alarms where multilayered alerting is required.
