18 mm Inductive Proximity Sensor
The Eaton E57G-18SPN5-Q is a cylindrical inductive proximity sensor with an 18 mm diameter stainless steel body. It detects metal targets up to 5 mm away using a shielded sensing face. The unit operates on 10 to 30 V DC and provides a 3 wire PNP normally open output through a 4 pin micro DC connector. It is rated IP67 and NEMA 4X for harsh environments.
Suits Automated Machine Detection
This sensor suits automation engineers who need reliable metal detection on conveyors, packaging lines or machine tooling. The shielded design allows flush mounting in metal brackets without interference. The 1,200 Hz switching frequency supports fast cycle rates. Buyers who need non-metallic detection, longer sensing ranges or analog output should look at other technologies.
Simple 4 Pin Wiring Install
Installation uses a standard 4 pin micro DC connector for quick wiring. The 10 to 30 V DC supply range matches common industrial power supplies. The 100 mA maximum load suits most PLC inputs directly. Ensure the target material and size match the 5 mm rated distance; exceeding the 158 °F temperature limit or mechanical impact on the sensing face are common causes of failure.

Questions about this item
What power supply range is required for the 10 to 30V DC sensor?
The sensor operates on 10 to 30V DC; provide a supply within that range with at least 100 mA available for the load.
Will the 4-pin micro DC connector fit my existing M12 cable?
Yes, the 4-pin micro DC connector is the standard M12 interface used on most industrial cables.
How can I verify the 1,200 Hz switching frequency after installation?
Use an oscilloscope on the output wire; a clean square wave at 1.2 kHz confirms the sensor is switching at its rated speed.
