The Telemecanique XUSL4E30H076L is a safety light curtain, classified under the Light Curtain sub-category. It's an optical guard that creates an invisible detection zone across an opening or hazard area — when any beam is blocked, the safety outputs switch off, stopping the machine. This is the kind of part you spec into a guarding circuit for a press, robot cell, or conveyor infeed where an operator needs access but the machine must stop before a hand reaches the pinch point.
What the sub-category tells you
The Light Curtain sub-category tells you this is a type-2 or type-4 safety device (the exact type depends on the specific model variant). It's designed to be wired into a safety relay or safety PLC input, not a standard digital input. The emitter and receiver must be aligned and the protective height and range matched to the hazard. The UPC 389119618451 is a 12-digit identifier for logistics — not a functional spec, but useful for cross-referencing in procurement systems.
