Important model reminder
FS-N series model difference (per KEYENCE official specs):
- FS-N11N / FS-N11P: main unit, 1 output, cable type - works independently
- FS-N12N / FS-N12P: expansion unit, 1 output, cable type (this product) - must connect to a main unit such as FS-N11N
- FS-N11CN / FS-N11CP: main unit, 1 output, M8 connector type
- FS-N12CN / FS-N12CP: expansion unit, 1 output, M8 connector type
- FS-N13N / FS-N13P: main unit, 2 outputs, cable type
- FS-N14N / FS-N14P: expansion unit, 2 outputs, cable type
Can FS-N12N work alone? No - it is an expansion unit. It shares the display and settings of the FS-N main unit it is connected to, so order it only when you already have (or are also ordering) a main unit.
FAQ
Q: Can the FS-N12N work as a stand-alone amplifier?
A: No. The FS-N12N is an expansion unit - it must be connected to an FS-N series main unit (such as the FS-N11N). If you need an amplifier that works alone, see our FS-N11N listing.
Q: What is the difference between FS-N12N and FS-N11N?
A: FS-N11N is the main unit with its own display and can work independently; FS-N12N is a matching expansion unit with 1 output that links to the main unit. Both are cable type, NPN, 12-24 VDC.
Q: What is the lead time for the FS-N12N?
A: This is a genuine unit sourced to order. Lead time is confirmed at quotation, typically 1-3 weeks, and every unit is inspected before shipment.
Typical applications
- Adding detection points to an existing FS-N main unit, multi-point centralized monitoring, line expansion without replacing the main amplifier
