Connecting an NPN sensor to a PNP PLC input will result in no signal. Refer to your wiring diagram every time.
Can support up to 16 expansion units (17 total units including the main unit). Power Supply: 10 to 30 VDC, Class 2 or LPS. fs-n41p manual
When you are working with industrial automation, precision fiber optic sensors are the unsung heroes of the assembly line. Among these, the (often grouped with the FS-N40 series by Keyence) stands out as a high-performance, energy-efficient fiber optic amplifier. However, like any sophisticated piece of equipment, unlocking its full potential requires more than just a quick glance at a spec sheet. It demands a deep dive into the FS-n41p manual .

The most common cause of sensor failure is incorrect wiring. Page 12 of the provides a clear pinout. Here is the breakdown:
The KEYENCE is a high-performance, digital fiber optic sensor belonging to the advanced FS-N40 series . As a PNP main unit with a cable connection, it is designed for precision detection in industrial automation, offering high power, an easy-to-read OLED display, and a streamlined setup process. Core Specifications of the FS-N41P
If you have two FS-N41P sensors mounted side-by-side, they can cross-talk. Sync them:
