The XUSL4E14F166N is a Type 4 safety light curtain from the XUSL series, configured as a receiver-transmitter pair with 165 beams across a 1.66m protective height. The 14mm detection capability means it catches fingers reaching into the hazard zone — finger-protection class per IEC 61496-1, not just hand or body detection. That resolution paired with the 1.66m height suits it for guarding large access openings on assembly lines, packaging machines, or robotic cells where an operator might reach through. Operating range runs 0 to 6.0m, so the emitter and receiver can be spaced up to 6 meters apart while maintaining reliable detection. The IP65/IP67 rating means the sensor housings and optics withstand washdown environments — suitable for food-and-bev lines or outdoor installations where hosed cleaning is routine. Supply is 24VDC, standard for safety circuits in industrial control panels. The 14mm resolution and Type 4 safety category (highest per IEC 61496-1) make this a direct fit for guarding applications that require SIL 3 / PL e compliance.
That means factory support, replacement availability, and consistent spec conformance for new designs and existing BOM lines.
