What this Type 4 light curtain does on the line
The XUSL4E2BB051NS1 is a Type 4 safety light curtain from the XUSL series, configured as a receiver and transmitter pair with 2 beams and a 510 mm protective height. Its 0 to 12.0 m operating range covers long access zones on a conveyor or press line — enough to guard a wide opening without stacking multiple units. Rated IP65/IP67, the body and optics hold up to washdown and outdoor moisture, so it fits food-processing or tire-curing environments where steam and high-pressure cleaning are routine. The -30°C to 55°C operating temperature means it can sit near a curing press without thermal drift. Powered by 24 VDC, the pair draws from a standard safety relay or safety PLC output. Two beams at 510 mm protective height means it catches a hand or torso reaching into the hazard zone — finger detection requires a higher-resolution model, but for body and limb guarding this is the right density.
