When a metal object enters the 4mm sensing range, the output switches LOW (pulls to GND), completing the circuit. This is a standard NPN configuration compatible with most PLCs and microcontrollers.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What materials can the WTB11-2N2461 inductive sensor detect?\u003c\/h4\u003e\n\u003cp\u003eA: As an inductive proximity sensor, the WTB11-2N2461 is designed to detect ferrous and non-ferrous metals, including steel, iron, aluminum, copper, and brass. The rated 4mm sensing distance applies to standard mild steel targets; non-ferrous metals may have a slightly reduced effective sensing range.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is this sensor compatible with Arduino, Raspberry Pi, or PLCs?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The NPN output is widely compatible with PLCs, Arduino (with a suitable voltage divider or level shifter if using 5V logic), and other industrial controllers. Ensure your control system's input accepts NPN (current-sinking) signals and that the supply voltage falls within the 6–36V DC operating range.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the IP rating or environmental protection of this sensor?\u003c\/h4\u003e\n\u003cp\u003eA: While a specific IP rating is not listed in the product data, inductive proximity sensors of this type are generally housed in a rugged metal barrel suitable for typical industrial environments. For use in wet or high-dust environments, please verify the datasheet specifications or contact us for additional details.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What does NPN Normally Open (NO) mean for this proximity sensor?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"NPN Normally Open (NO) means the output signal wire is at an open (HIGH-impedance \/ disconnected) state when no metal target is detected.
