Product Description

About selection

Ultra-thin Light Curtain (Side Detection) Series	K033E
Number of optical axes	4: 4 axes, 6: 6 axes, 8: 8 axes (For other axis quantities, refer to the selection table)
Optical Axis Pitch	10：10mm 20：20mm 40：40mm
Output Mode	Blank: NPN Output P: PNP Output NP: NPN + PNP Output
Operating Status	Blank: Normally Closed (NC)NO: Normally Open (NO)
Synchronization Mode	Blank: Line Synchronization G: Optical Synchronization
Protection Distance	D1:0~1m D3:1~3m D5:1~5m D7:1~7m

Model Selection Example:

K033E-8-10(D1) refers to the K033E series, with 8 optical axes, 10 mm optical axis pitch, NPN output, normally closed state, line synchronization, and a protection distance of 1 meter.

K033E-8-10NP-NO-G(D7) refers to the K033E series, with 8 optical axes, 10 mm optical axis pitch, NPN+PNP dual output, normally open state, optical synchronization, and a protection distance of 7 meters.

Note:

For line synchronization, either NPN or PNP output is optional; optical synchronization only supports NPN+PNP dual output.
When purchasing brackets separately, the ordering models are: K033E-L1, K033E-L2.
