Overview
The Eaton Cutler-Hammer E51SCL /B2 is an assembled inductive proximity sensor from the E51 modular limit switch series. This NEMA 3–rated unit delivers 1.0 Amp solid state output at 120 VAC input, making it suitable for machine control, automation, and industrial equipment applications. The die-cast zinc enclosure provides durability in factory and stationary equipment environments.
