Schneider Electric Telemecanique XCKML121 Limit Switch

The Schneider Electric Telemecanique XCKML121 is a heavy‑duty electromechanical limit switch from the XC Standard family, built with a fixed body and a plunger head for robust end‑of‑travel sensing. It uses a spring‑return thermoplastic roller lever plunger and dual snap‑action contact blocks (2 × (1 NC + 1 NO)), with screw‑clamp terminals and three Pg 13.5 cable entries for rugged, field‑wired installation. Ideal for conveyors, packaging machinery, machine tools, automated production equipment, and material handling systems, it provides reliable mechanical position detection and end‑of‑travel switching; common replacements include XCKML121H7 and XCKML102.
