3RG4023-3AG01 M18 Inductive Sensor with PNP Normally Open Output

The 3RG4023-3AG01-PF is a compact inductive proximity sensor developed for short-range, non-contact metal detection in industrial automation. The publicly available Pepperl+Fuchs datasheet for this connector version identifies it as a cylindrical M18, non-embeddable sensor with M12 connector, 3-wire DC PNP output, and normally open switching behavior. For machine builders and maintenance engineers, that combination is a practical fit for PLC-based 24 V DC control systems.

This model is well suited to applications where stable close-range detection matters more than long sensing distance. Its official data shows an 8.0 mm rated operating distance, 15 to 34 V DC supply range, and 200 mA rated current up to 50 °C. In practical industrial use, that means it can be applied to bracket sensing, indexing, gate position monitoring, machine sequence confirmation, and part presence detection in compact automation assemblies.

From a durability standpoint, the sensor is built for real production environments rather than bench-top duty. The datasheet specifies IP67 protection, brass housing, built-in short-circuit, overload, and reverse-polarity protection, plus operation from -25 to +85 °C. Pepperl+Fuchs conformity documents also identify the model as an inductive sensor under EN IEC 60947-5-2 and EN IEC 63000, which is helpful for engineering review and procurement approval.

FAQ

Q1: What kind of applications is 3RG4023-3AG01 best suited for?
It is best suited for short-range metal detection in compact automation systems. Typical uses include part presence sensing, position confirmation, indexing control, gate or stopper monitoring, and sequence feedback in machines that use standard 24 V DC PLC architecture.

Q2: What does PNP normally open mean in practice?
A PNP normally open output means the sensor provides a positive output signal when a metal target is detected. In practical terms, this matches many PLC digital input designs used in industrial automation and makes the device easy to integrate into sourcing-input control logic.

Q3: Is the sensing distance 6 mm or 8 mm?
The publicly accessible Pepperl+Fuchs datasheet for 3RG4023-3AG01-PF shows a rated operating distance of 8.0 mm. So for a product page based on the verifiable datasheet, 8.0 mm is the safer and more accurate figure to use.

Q4: Is this sensor robust enough for industrial service?
Yes. The datasheet lists IP67 protection, brass housing, operation from -25 to +85 °C, and built-in electrical protection functions such as short-circuit and overload resistance. Those features support reliable use in factory environments where moisture, vibration, and routine machine duty are expected.

Q5: Does this model meet recognized industrial standards?
Yes. Pepperl+Fuchs conformity documents list 3RG4023-3AG01-PF as an inductive sensor covered by EN IEC 60947-5-2 and EN IEC 63000. That is valuable for buyers who need traceable compliance information during technical review, procurement approval, or machine documentation work.
