Cylindrical stainless steel inductive sensor 18 mm diameter 45 mm length 4 pin micro connector

Eaton

Eaton E57PS-18SPN5-Q Inductive Proximity Sensor 18 mm

SKU CH-EDRN-Y1EMT

An 18 mm shielded inductive sensor detects metal up to 5 mm away with a 10 to 48 V DC supply and 300 mA PNP output

  • Reliable detection up to 5 mm range
  • 10–48 V DC supply fits many control systems
  • 3-wire PNP NO output simplifies PLC wiring
  • IP69K and NEMA 4X ratings resist high-pressure washdown
  • Stainless-steel body operates from -13 °F to 158 °F

18 mm Inductive Sensor for Industrial Detection

The Eaton E57PS-18SPN5-Q is an 18 mm cylindrical inductive proximity sensor built for industrial automation. It detects metal targets at close range in harsh environments. The shielded stainless steel housing resists mechanical damage and corrosion. It suits machine builders and maintenance teams needing reliable presence sensing.

5 mm Sensing Range with 10 to 48 V DC Supply

The sensor offers a maximum detecting distance of 5 mm, providing a narrow, precise detection zone for small parts. It operates on a 10 to 48 V DC supply, compatible with common industrial control voltages. A 300 mA maximum current load drives typical PLC inputs or relays directly. The 1 200 Hz switching frequency supports fast cycling applications.

4-Pin Micro Connector with IP69K Protection

Electrical connection uses a 4-pin micro connector for quick installation and replacement. The PNP normally open output simplifies wiring to positive-logic controllers. NEMA 4X and IP69K ratings withstand high-pressure washdown and aggressive chemicals. The operating temperature range spans -13 to 158 degrees F for extreme ambient conditions.

Questions about this item

Will the 18 mm threaded barrel fit the existing mounting holes on my older machine frame?

The sensor has an 18 mm diameter cylindrical body with a 45 mm overall length, so it matches standard 18 mm mounting cut-outs used on many legacy frames.

How can I verify the PNP output is switching correctly after wiring the 4-pin micro connector?

Apply 10 to 48V DC, bring a metal target within the 5 mm sensing range, and measure for a high signal on the output wire; the 1,200 Hz operating frequency allows rapid on-off testing.

Does the package include a mating 4-pin cable or must I source one separately?

Only the sensor with its integral 4-pin micro connector is supplied; a compatible 4-pin cordset must be purchased separately to complete the electrical connection.
