Frequently Asked Questions
Q: What type of output does the SN08-N proximity switch use?
A: The SN08-N uses an NPN, 3-wire, Normally Open (NO) output. This is a standard output type that is compatible with most PLCs, Arduino boards, and industrial automation controllers operating on DC 10V to 30V.
Q: What materials can the SN08-N proximity switch detect?
A: 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.
Q: What is the maximum sensing distance of the SN08-N?
A: 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.
Q: Is this proximity switch suitable for outdoor or harsh environments?
A: 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.
