Eaton Inductive Proximity Sensor, Unshielded, Stainless Steel

Eaton E57 Inductive Proximity Sensor, Unshielded, Stainless Steel

The Eaton E57 Inductive Proximity Sensor is a straight-body, unshielded mini sensor built in 303 stainless steel with a 360° viewable LED indicator for fast status checks from any angle. Rated for 20-250 V input with a 250 mA at 250 V contact rating (2-wire AC, NO), this E57 series sensor is engineered for demanding automation and machine-control environments where reliable, non-contact target detection is required. With a compact .71 in width/height and 3.39 in length/depth, it fits tight mounting locations while maintaining sensing accuracy of less than 3% of sensing range across a -13°F to 122°F operating temperature window.

Key Features
