Overview
The Eaton Cutler-Hammer E57-12PAU04-AD is a compact 12mm inductive proximity sensor from Eaton’s Global Plus Prox series. This 2-wire AC model delivers reliable object detection without physical contact across industrial automation, manufacturing, and machinery control applications. The sensor operates at 20–250V AC, making it compatible with standard industrial AC power supplies.
Key Features
- 12mm cylindrical housing for tight mounting spaces
- 4mm sensing range for close-proximity detection applications
- 2-wire AC design reduces wiring complexity and cost
- Connector output type (PAU series designation) for quick disconnect
- Bright LED indicator shows output status in real time
- Rugged stainless-steel face resists abrasion and corrosion
Technical Specifications
The sensor is rated for 20–250V AC operation with a standard 100 mA load current capacity. Housing diameter is 12mm with an overall length of 60mm and sensing face diameter of 12mm. The sensing range is 4mm, suitable for metal detection at short distances. Wiring is provided via connector configuration for secure, repeatable connections. Operating temperature range is 0–60°C, with storage temperature to −20°C. The unit is RoHS compliant for environmental regulations.
