The PSN17-5DN has a detection distance of approximately 4 mm, while the PSN17-8DN offers an extended detection distance of approximately 8 mm. Both share the same NPN 3-wire normally-open output, 10–30 V DC operating range, and 18 × 18 × 36 mm housing dimensions.\u003c\/p\u003e\n\u003ch4\u003eQ: Is this proximity sensor compatible with a PLC or automation controller?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The NPN normally-open (NO) 3-wire output is the most widely used configuration for PLCs, relay modules, and automation controllers. Simply connect the brown wire to positive supply (10–30 V DC), the blue wire to negative\/ground, and the black output wire to your PLC input terminal.\u003c\/p\u003e\n\u003ch4\u003eQ: Can this sensor detect all types of metal?\u003c\/h4\u003e\n\u003cp\u003eA: As an inductive proximity sensor, it detects ferrous and non-ferrous metallic objects. Detection range may vary slightly depending on the target metal type (e.g., the rated distance applies to standard mild steel targets; aluminium or copper may have a reduced effective range).\u003c\/p\u003e\n\u003ch4\u003eQ: What certifications does the PSN17-5DN \/ PSN17-8DN carry?\u003c\/h4\u003e\n\u003cp\u003eA: This proximity sensor is CCC (China Compulsory Certificate) and CE certified, confirming it meets both Chinese national safety standards and European electromagnetic compatibility requirements for industrial use.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What is the difference between the PSN17-5DN and PSN17-8DN proximity sensor models?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The main difference is the sensing distance.
