The Patlite LR4 Series Ø40mm LED signal tower is designed for machine status indication, andon systems, and process alerts in space-constrained installations. The series provides a modular, twist-and-lock build that lets LED and sound modules be configured or replaced in the field without tools, and supports both 24V DC and 100-240V AC power. Its IP65-rated housing helps the tower hold up to dust and washdown in everyday industrial environments.
