First, determine the optical axis spacing of the safety light curtain (resolution of the safety light curtain)

Because the safety light curtain has finger protection, palm protection, arm protection and human body protection. The selected optical axis spacing will also be different for different protection types.

Finger protection: the optical axis spacing is generally about 10mm

Palm protection: The distance between optical axes is generally around 20-30mm.

Arm protection: the optical axis spacing is generally about 40mm

Protection of the human body: the distance between the optical axes is generally about 80mm.

Second, determine the protection height of the safety light curtain

To distinguish between the height of the safety light curtain and the protective height of the safety light curtain (the height of the safety light curtain: the overall height of the safety light curtain; the protective height of the safety light curtain: simply the distance between the beams) can also be based on the safety light The number of curtain beams to determine the protection height of the light curtain

Third, determine the distance of the safety light curtain

Through-beam distance: The distance from the emitter to the receiver of the safety light curtain. The shooting distance of KT safety light curtain can reach 24m, and the shooting distance can be determined according to the actual situation.

Fourth, to determine the output type of the light curtain

Output types are: E: digital signal output; none: PNP/NPN signal output P: dual-channel PNP signal output N: dual-channel NPN signal output M: relay signal output
