The GFS series ultra-small laser sensors are compact, high-precision devices ideal for industrial automation. They feature detection distances of 2-50mm (diffuse) and 2000mm (through-beam), with a fast response frequency of 1ms. These sensors utilize a red LED light source (650nm) and diffuse type offer a stable light spot size of Φ4mm. Constructed from stainless steel SUS316L, they provide IP65 protection and operate within -20°C to +60°C. With reverse connection and load short circuit protection, these sensors ensure reliable performance in various applications, including detecting small objects and high-speed moving targets. Their small size and easy installation using standard M3 screws make them perfect for space-constrained environments.
