Selection example: K037 B-16-20 means K037B series, the number of optical axes is
16, the distance between optical axes is 20mm, and NPN output. K037B-16-20P
means K037 B series, the number of optical axes is 16, the distance between optical axes is 20mm, and PNP output.
Note: When ordering the bracket separately, the order model is: K037B-L1, K037B-L2

D:Optical axis distance
Optical axis distance D | 10 | 20 | 40 |
