The Telemecanique XUSL4E30H091NS1 is a Light Curtain — a safety-rated optoelectronic guard used to detect personnel or objects entering a hazardous zone. Its sub-category is Light Curtain, meaning it creates an invisible detection plane across an opening; when any beam is blocked, the machine's safety circuit receives a stop signal. This is the kind of part a controls integrator specifies for press brakes, robotic cells, or automated assembly lines where a physical barrier isn't practical but a Category 4 / SIL 3 safety function is required.
What the Light Curtain Rating Means for Fit
The XUSL4E30H091NS1 is a Light Curtain, which means the key selection parameters are detection resolution, protected height, and range — not raw current or voltage. The 30 in the model string typically indicates 30 mm resolution (finger detection), and the 091 suggests a 910 mm protected height, though the exact values should be confirmed against the datasheet for your specific guarding application. The UPC 389119620102 is a fixed identifier for this variant, useful for traceability in procurement systems and for matching against incoming goods.
