Selection Tips for Light Curtain Machine Guarding

For optimal performance and correct application, please consider the following selection criteria:

1. Choose Beam Spacing (Resolution):

• 10mm Spacing: For finger protection or detection of objects larger than 10mm.
• 20mm Spacing: For hand/palm protection or detection of objects larger than 20mm.
• 40mm Spacing: For arm/elbow protection or detection of objects larger than 40mm.

2. Determine Protection Height:

Protection Height is the vertical distance between the highest and lowest light beams – the effective detection zone. It is calculated by the formula:
Protection Height = Beam Spacing × (Number of Beams – 1).

3. Select Output Signal:
Choose the transistor output signal that matches your control system's requirements:

• NC (NPN Normally Closed): Outputs 0V when the beam is clear; no output when blocked.
• NO (NPN Normally Open): No output when clear; outputs 0V when blocked.
• PC (PNP Normally Closed): Outputs 24V when the beam is clear; no output when blocked.
• PO (PNP Normally Open): No output when clear; outputs 24V when blocked.

4. Choose Mounting Style:

The ultra-slim design allows for side mounting on machinery.
