Cylindrical stainless steel inductive proximity sensor 18 mm diameter 66 mm length 2 m cable

Eaton

Eaton E57G-18UPN8-C2 inductive proximity sensor 18 mm

SKU CH-B095-X6F73

18 mm unshielded inductive sensor detects metal at 8 mm, runs on 10 to 30 V DC with a 3-wire PNP output, IP67 stainless steel body, 2 m cable, -13 to 158 °F range

  • Detects metal at 8 mm with 1200 Hz switching
  • 10 to 30 V DC supply fits standard control voltages
  • PNP normally-open output simplifies PLC wiring
  • IP67 and NEMA 4X stainless body resists wash-down
  • Operates from -13 °F to 158 °F for harsh environments

Eaton 18 mm Inductive Proximity Sensor

The Eaton E57G-18UPN8-C2 is a cylindrical inductive proximity sensor designed for industrial automation and machine-shop equipment. It detects metal targets at distances up to 8 mm using a 3-wire PNP output that switches normally open. The 10 to 30 V DC supply range suits standard control-voltage systems.

Sensing Limits and Electrical Interface

The unshielded sensing face operates at 1,200 Hz, which sets the practical speed limit for repetitive detection tasks. A maximum load of 100 mA restricts the sensor to driving PLC inputs, small relays or indicator circuits directly. The 2 m cable provides a fixed connection length that cannot be adjusted in the field.

Stainless-Steel Build and Sealed Mounting

A stainless-steel housing rated IP67 and NEMA 4X resists water jets, coolant splash and dust ingress in harsh environments. The 66 mm body length and 18 mm diameter fit standard M18 mounting holes without adapters. Operating temperatures from -13 to 158 °F allow use in unheated shops and outdoor machinery year-round.

Highlights

  • Detects metal at 8 mm with 1200 Hz switching
  • 10 to 30 V DC supply fits standard control voltages
  • PNP normally-open output simplifies PLC wiring
  • IP67 and NEMA 4X stainless body resists wash-down
  • Operates from -13 °F to 158 °F for harsh environments

Questions about this item

Should I choose the 18 mm model with 8 mm sensing range or a different diameter?

The 18 mm diameter sensor detects metal targets up to 8 mm away, unshielded mounting means you need clearance around the face, and the 2 m cable suits panel wiring without extra connectors.

What does the 1,200 Hz operating frequency mean on a production line?

The sensor updates its output 1,200 times per second, so it can reliably detect parts moving at high speed on conveyors or indexing tables without missing cycles.

How does the 10–30 V DC supply and PNP output work with my PLC?

It accepts any DC supply between 10 and 30 V, the PNP output sources up to 100 mA to the PLC input, and the normally-open logic closes the circuit only when metal enters the 8 mm zone.
