North American Signal DFS1250-ACR Heavy-Duty Industrial Strobe Beacon, 120 VAC, 60 FPM (Double Flash), 18-Joule Output, Stainless Base, Inner Fresnel Lens with Smooth Outer Dome — Permanent Through-Bolt Mount

Condition: Used, working. Typical cosmetic wear from prior service; no additional accessories or hardware beyond what’s pictured or stated.

Built for demanding industrial and off-road environments, the North American Signal DFS1250-ACR is a high-energy 120-volt strobe beacon with a stainless-steel base, an inner Fresnel lens for efficient light shaping, and a smooth outer dome for durability and easy cleaning. Its double-flash (60 FPM) pattern and 18-joule energy deliver attention-grabbing visibility on machinery, loading docks, gates, and plant safety stations.

Features

• 120 VAC, 60 Hz power — ideal for fixed equipment and facility use

• High-output xenon strobe: 18 J energy, approx. 900 candela-seconds light output

• 60 flashes per minute (DF) double-flash pattern for enhanced conspicuity

• Stainless-steel base resists corrosion in harsh settings

• Inner Fresnel + smooth outer dome: efficient optics with an easy-to-wipe exterior

• Permanent through-bolt mount (standard) for secure installation

• Rugged, serviceable design common to heavy-duty equipment

Part of Larger Systems / Integration Notes

• Wire to a 120 VAC switched circuit or control relay from your machine/PLC.

• Use appropriate gasket, hardware, and strain relief for the mounting surface.

• For outdoor use, confirm dome color, IP/weather rating, and provide a drip loop and sealant as needed.

• Always follow site electrical codes and lockout/tagout during installation.
