The Festo SIE-Q-PS-K=LED is an inductive proximity switch with a cable connection and a built‑in LED indicator. It provides non‑contact sensing of metal targets for position or presence feedback in automation, conveyors, and machinery without moving parts subject to wear. The LED status offers immediate visual confirmation of the sensing state, and the SIE-Q-PS-K=LED designation specifies this LED‑enabled, cable‑lead variant from Festo.
