The Siemens 3RA9012-5CL63 is a five-color LED stack light kit — red, green, yellow, blue, and clear — running on 24 VDC and terminated via cage clamp connections. It ships as a complete assembly: base, riser, and all five light modules in one order code, so there is no piecemeal sourcing across multiple line items.
What the cage clamp means on the line
Cage clamp termination means you land solid or ferruled stranded wire directly into the light base without screwing down a terminal — quicker install, no torque check, and it holds under vibration on a conveyor or machine tool. The 24 VDC supply is standard for most PLC digital outputs, so this stack light can be driven straight from a 24 VDC control card without an interposing relay.
