Eaton E51 Series Inductive Proximity Sensor, NEMA Rated
The Eaton E51 Series Inductive Proximity Sensor is an inductive proximity sensor built for demanding industrial sensing applications where reliable, non-contact detection is required. Housed in a compact plastic enclosure measuring 1.51 in wide, 1.51 in deep, and 1.38 in high, this sensor delivers accuracy of less than 0.3% and is rated NEMA 3, NEMA 3S, NEMA 4, NEMA 4X, NEMA 6, NEMA 6P, NEMA 12, NEMA 13, and IP67 for use in harsh, wet, and washdown environments. It carries UL Listed certification and is CE Marked, making it a dependable choice for professional automation and machine control installations.
Key Features
- Compact Footprint: Product Width of 1.51 in and Product Length/Depth of 1.51 in for space-constrained mounting.
- Low-Profile Height: Product Height of 1.38 in suits panel and machine-frame installation.
- Durable Construction: Plastic enclosure resists corrosion while supporting demanding NEMA-rated environments.
- Sensor Type: Inductive proximity sensing technology for reliable non-contact target detection.
- High Accuracy: Rated accuracy of < 0.3% for precise, repeatable switching performance.
- Wide Operating Temperature Range: Rated from -13 °F minimum to 158 °F maximum for indoor and outdoor use.
