1140157

Overview

The SICK model 1140157 is a VL18-4N3140 photoelectric retro-reflective sensor designed for industrial automation. It features an M18 cylindrical housing with axial optical axis and visible red LED light source. The sensing range reaches up to 3.7 meters when used with the C110A reflector, or 3 meters without specific reflector constraints. Dimensions are 18mm x 18mm x 78mm. The device operates with a dispersion angle of approximately 2.8 degrees and a light spot size of Ø150mm at 3m distance. Average service life is 100,000 hours at +25°C ambient temperature.
