Important model reminder
FS-N series model difference:
- FS-N11N / FS-N11P: main unit, works independently, cable-out version (this product)
- FS-N11CN / FS-N11CP: M8 connector type, NOT a direct swap for cable-out FS-N11N
- FS-N12N / FS-N12P: expansion unit, 1 output, cable type - must connect to a main unit such as FS-N11N
- FS-N13N / FS-N13P: main unit, 2 outputs, cable type; FS-N14N / FS-N14P: expansion unit, 2 outputs, cable type
- FS-N11 fiber amplifier is NOT the same as PS-N11 photoelectric amplifier - they cannot be interchanged

FAQ
Q: Can I directly replace the original Keyence FS-N11N with this unit?
A: Yes - pin-to-pin compatible for the cable-out FS-N11N / FS-N11P. Same dimensions, DIN rail mounting and pin definition. You can reuse your existing FU fiber optic cables without rewiring.
Q: What is MEGA mode for?
A: MEGA mode improves anti-interference performance and suits dusty, oily or electrically noisy production lines - common in electronic assembly factories across Southeast Asia.
Q: Can the FS-N13N expansion unit be used alone?
A: No. FS-N13N / FS-N14N are expansion units and must be connected behind an FS-N11 main unit.
Q: Can I use this amplifier with other brands of fiber heads?
A: It is designed for the FU series fiber heads (Keyence standard fiber interface). We recommend matching FU fiber heads for best performance.
Q: What are your shipping and warranty terms?
A: 12-month warranty; every unit is tested before shipment. We ship worldwide to factory maintenance teams, automation integrators and trading companies.
