This is a standard output type that is compatible with most PLCs, Arduino boards, and industrial automation controllers operating on DC 10V to 30V.\u003c\/p\u003e\n\u003ch4\u003eQ: What materials can the SN08-N proximity switch detect?\u003c\/h4\u003e\n\u003cp\u003eA: As an inductive proximity switch, the SN08-N is designed to detect metallic objects. It works best with ferrous metals (such as iron and steel) and can also detect non-ferrous metals (such as aluminum and copper), though detection distance may vary by material.\u003c\/p\u003e\n\u003ch4\u003eQ: What is the maximum sensing distance of the SN08-N?\u003c\/h4\u003e\n\u003cp\u003eA: The SN08-N inductive proximity switch has a rated detection distance of 8 mm. For optimal and consistent performance, it is recommended to position the target metal object within this range.\u003c\/p\u003e\n\u003ch4\u003eQ: Is this proximity switch suitable for outdoor or harsh environments?\u003c\/h4\u003e\n\u003cp\u003eA: The SN08-N features a plastic casing and is best suited for indoor industrial and workshop environments. For outdoor or high-moisture applications, consider housing the sensor in an appropriate enclosure to protect it from environmental exposure.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What type of output does the SN08-N proximity switch use?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The SN08-N uses an NPN, 3-wire, Normally Open (NO) output.
