The XUSL4E30H181L is a Type 4 safety light curtain from the XUSL series, rated for hand and arm protection with a 30mm detection capability. That 30mm resolution means it catches fingers and hands reaching into the hazard zone — finger-protection class per IEC 61496-1 — so it suits guarding around press brakes, assembly stations, and robotic cells where a 14mm finger curtain would be overkill but a 50mm body curtain insufficient. The 1.81m protective height covers a full standing operator's reach, and the 20m operating range lets you mount the emitter and receiver across a wide machine opening. IP65/IP67 ingress protection means the sensor housings and optics withstand washdown and temporary submersion — suitable for food-and-bev lines, wet machining areas, or outdoor conveyor gantries where dust and water jets are routine. The 24VDC supply is standard for safety circuits, and the 91 beams across the 1.81m height give a dense detection field with no blind zones between the emitter and receiver.
Deployment context
Mounts with the standard XUSL brackets and alignment hardware — the emitter and receiver align optically via the visible LED indicators. In a typical safety circuit, the outputs connect to a safety relay or safety PLC input module (SIL 3 / PL e rated). The IP65/IP67 rating means no additional enclosure is needed for washdown zones, but the M12 connectors must be properly torqued to maintain the seal.
