EATON E57G-12SPN2-Q Inductive Proximity Sensor 12 mm

SKU CH-PKXX-Q4R5Y

Detects metal objects within 2 mm using a 12 mm shielded stainless-steel barrel operating on 10 to 30 V DC with a 3-wire PNP output and IP67 rating

  • Detects metal at 2 mm with 2 000 Hz switching speed
  • Operates on 10 to 30 V DC with 100 mA max load
  • IP67 and NEMA 4X ratings resist water and dust
  • Stainless-steel housing endures -13 °F to 158 °F
  • 4-pin micro DC connector enables quick shielded installation

12 mm Inductive Proximity Sensor

The Eaton E57G-12SPN2-Q is a cylindrical inductive proximity sensor with a 12 mm diameter stainless steel body. It operates on 10 to 30V DC supply voltage and provides a 3-wire PNP normally open output. The sensor detects metal targets at a maximum distance of 2 mm with a 2,000 Hz switching frequency.

Shielded 4-Pin Micro DC Connector

The shielded design allows flush mounting in metal without interference from surrounding material. Electrical connection uses a 4-pin Micro DC connector for quick wiring. The 69 mm overall length fits standard 12 mm sensor mounting holes. IP67 and NEMA 4X ratings protect against dust and water ingress during installation.

Sustained Operation in Harsh Environments

The sensor maintains consistent detection performance across an operating temperature range of -13 to 158 degrees F. Stainless steel construction resists corrosion in washdown and chemical exposure scenarios. The 100 mA maximum current load supports continuous signalling to PLC inputs or relay coils without thermal derating. Not suited for applications requiring longer sensing ranges or non-metallic target detection.

Questions about this item

How do I verify the 12 mm sensor is detecting correctly after wiring the 4 pin micro DC connector?

Apply 10 to 30V DC power, bring a metal target within the 2 mm max detecting distance, and confirm the 3 wire PNP NO output switches at up to 2,000 Hz with a load not exceeding 100 mA.

What comes in the box with the E57G-12SPN2-Q and what must I source separately?

The sensor ships with its stainless steel cylindrical body, shielded 12 mm face, and integral 4 pin micro DC connector; you must supply a compatible 4 pin cable, a 10 to 30V DC power source, and mounting hardware for the 69 mm length.

Which output and connection version should I choose for a 10 to 30V DC system needing a normally open signal?

Select the 3 wire PNP normally open version with the 4 pin micro DC connector, rated for 100 mA max current load and 2,000 Hz operating frequency, matching your supply voltage and wiring scheme.
