Conventional safety light curtain selection core parameter guide
The following 5 key data are required when purchasing
Protection height or total height
Provide us with the protection height. If the location is narrow and the total height of the light curtain needs to be limited, please tell us and we will select the right model for you.
Formula: number of beams × optical axis spacing - 1 optical axis spacing
Example: If the optical axis spacing is 14mm and the number of beams is 20, then the protection height = 14×20-14=266mm
01
Optical axis spacing selection
Finger protection: 10/14mm (precision operation scenario)
Palm protection: 30/40mm (machining/assembly line)
Human body detection: 80/200mm (large area protection)
02
Distance of the beam (detection range)
The maximum installation distance between the transmitter and the receiver (unit: meter) must be greater than the actual distance between the equipment
03
Output type
NPN: NC (normally closed)/NO (normally open)
PNP: NC (normally closed)/NO (normally open) (NC is the mainstream choice in industry)
Relay: 1NC/1NO (NPN or PNP scenario is not confirmed)
04
Light curtain controller QCA: AC 110~220V, single channel automatic reset
Safety relay SRC106: DC24V, supports manual/automatic reset dual mode
