The XUSL4E30H031N is a Type 4 safety light curtain from the Schneider Electric XUSL series, combining a receiver and transmitter in one orderable pair. Its 30 mm detection capability means it catches fingers and hands reaching into a hazard zone — that is finger-protection class per IEC 61496-1, not just presence detection. The 310 mm protective height and 12 m operating range cover access openings on a typical assembly line or machine cell.
16 beams spaced across the 310 mm protective height give a 30 mm resolution — that is the smallest object the curtain reliably detects. A 24 VDC supply is standard for safety circuits; the IP65/IP67 rating means the sensor body and optics withstand washdown and temporary immersion, suitable for food-and-bev or outdoor deployment. The -30°C to 55°C operating temperature range covers cold storage and hot factory environments without derating.
