Frequently Asked Questions
Q: What is the difference between the PSN17-5DN and PSN17-8DN proximity sensor models?
A: The main difference is the sensing distance. 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.
Q: Is this proximity sensor compatible with a PLC or automation controller?
A: 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.
Q: Can this sensor detect all types of metal?
A: 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).
Q: What certifications does the PSN17-5DN / PSN17-8DN carry?
A: 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.
