Schneider Electric 9001SKP1Y31 Indicator Light

Schneider Electric 9001SKP1Y31 Indicator Light is a 30 mm, panel-mount pilot light designed to provide a bright yellow status signal on control panels and automation enclosures. The SKP1 variant belongs to the Harmony 9001 family and carries the Y31 color code for a yellow indicator, suitable for signaling distinct machine or process conditions. It operates from 110–120 V AC at standard industrial frequencies (50–60 Hz), and uses a Fresnel-style yellow lens, with a polycarbonate lens material for clear visibility and durability in demanding environments. This 30 mm module is intended for installation in a 30 mm panel cutout, enabling straightforward integration with standard Schneider Electric field devices and compatible contact blocks when a visible status indicator is required on 120 V circuits. Common applications include signaling and status indication on motor controllers, PLC control panels, and other industrial equipment where a reliable yellow pilot light is used to denote operation, fault, or standby conditions.
