Eaton 12 mm Inductive Proximity Sensor
The Eaton E57G-12UPN4-C2 is a cylindrical inductive proximity sensor designed for industrial automation and machinery applications. It detects metal targets without physical contact in manufacturing or material handling environments. The unshielded design suits flush or non-flush mounting requirements. This sensor serves engineers and maintenance technicians needing reliable presence detection.
4 mm Sensing Range with 2 kHz Switching
The sensor offers a maximum detecting distance of 4 mm with an operating frequency of 2,000 Hz for rapid cycling applications. It operates on a 10 to 30V DC supply with a 3-wire PNP normally open output. The maximum current load is 100 mA, limiting use to low-power control circuits rather than direct actuator driving. Longer-range or higher-current needs require a different sensor class.
Stainless Steel IP67 Housing with 2 m Cable
The stainless steel case measures 64 mm in length and carries NEMA 4X and IP67 ratings for washdown and submersion resistance. It withstands operating temperatures from -13 to 158 degrees Fahrenheit. A fixed 2 m cable provides the electrical connection, simplifying installation but preventing quick-disconnect replacement. The unshielded body requires careful spacing from surrounding metal to avoid false triggers.

Questions about this item
Will this 12 mm unshielded sensor detect metal targets reliably when mounted flush in a steel bracket?
The unshielded design requires a clear zone around the sensing face; mounting flush in metal will reduce the 4 mm range or cause false triggers, so keep the face clear per Eaton guidelines.
How can I confirm the 3-wire PNP output is switching correctly after wiring it to a 10-30 V DC supply?
With power applied, the brown wire to positive and blue to negative, the black output wire should go high when a metal target enters the 4 mm field; a multimeter or PLC input LED will show the change.
Does the 2 m pre-wired cable include a connector, or must I buy a mating plug separately?
The sensor ships with a 2 m integral cable and no separate connector; the cable ends are stripped for direct termination, so no extra plug is required.
