Industrial SF120A-3608 Solid State Flasher

Industrial SF120A-3608 Solid State Flasher is a 120 VAC solid‑state flasher designed for continuous‑duty signaling and indicator circuits in industrial control environments. It delivers a factory‑fixed flash rate of 75 FPM (±20%) when powered from a 50/60 Hz supply, and specifies a 1 A load current at 120 VAC. Implemented with AC full‑wave output, this unit is compatible with incandescent or resistive loads (Load Type A) and is commonly used in panels and beacons to provide a clear, eye‑catching flash for warnings or status indicators. The model is listed as discontinued by the manufacturer, reflecting its status in legacy equipment and older OEM signaling assemblies, yet it remains a reference point in SSAC flashers’ design and specifications. In practice, these flashers were designed for compact panel mounting and straightforward wiring in industrial environments where a reliable, constant flash cadence was required, and the 120 VAC input and 75 FPM rate were among the defining characteristics for selecting a compatible device.
