Cylindrical stainless steel inductive proximity sensor 12 mm diameter 64 mm length 2 m cable

Eaton

EATON E57G-12UNN4-C2 Inductive Proximity Sensor 12 mm

SKU CH-2BJ8-Z5ZZ7

Inductive proximity sensor detects metal at 4 mm with 10-30 V DC NPN output and IP67 stainless-steel housing

  • 12 mm cylindrical sensor fits tight machine spaces
  • 4 mm unshielded range detects metal targets reliably
  • 10 to 30 V DC supply works with standard controls
  • IP67 and NEMA 4X rating resists water and dust
  • Stainless steel body withstands -13 to 158 °F operating temperatures

Eaton 12 mm Inductive Proximity Sensor

The Eaton E57G-12UNN4-C2 is a cylindrical inductive proximity sensor designed for industrial automation and machinery applications. It detects metal targets without physical contact at a maximum range of 4 mm. The sensor operates on a 10 to 30V DC power supply with a 3-wire NPN output circuit. It suits engineers and maintenance teams needing reliable presence detection in harsh environments.

Stainless Steel IP67 Housing with 2 m Cable

The sensor body is constructed from stainless steel with a 12 mm diameter and 64 mm length, providing robust resistance to corrosion and impact. An IP67 and NEMA 4X rating ensures protection against dust ingress and temporary water immersion. The unshielded design allows for wider sensing fields. A fixed 2-meter cable simplifies wiring in control cabinets or junction boxes.

Replaces Worn Limit Switches or Older Sensors

This unit upgrades mechanical limit switches that suffer from physical wear and contact bounce over time. It also replaces older proximity sensors with lower ingress protection or slower 2000 Hz switching frequency. The jump is worthwhile when applications demand non-contact sensing, high cycle life, and reliable operation across a -13 to 158 degrees F temperature range with 100 mA load capacity.

Questions about this item

What voltage range does the 10 to 30V DC sensor actually accept in practice?

The sensor accepts any DC supply from 10 to 30 volts, matching common industrial control buses.

What mounting clearance does the 12 mm unshielded cylindrical body need?

The 12 mm diameter stainless-steel barrel is 64 mm long and requires a standard M12 mounting hole with space for the unshielded sensing face.

How is the 3-wire NPN cable connected, and which wire is commonly miswired?

Connect brown to positive, blue to negative, and black to the load; the black output wire is often mistaken for a ground connection.
