What the Specs Mean for Your Panel
The SMTO-4-NS-K-LED-24 is a Festo T-slot proximity switch, designed to slide into the groove of a pneumatic cylinder. The LED indicator gives you a quick visual on switching state — useful during commissioning when you're walking the line with a laptop. No separate bracket or mounting kit needed if the cylinder has the slot; it's a direct-fit part that saves panel space because the sensing happens at the actuator, not back in the cabinet.
