Balluff Inc., the US subsidiary of Germany-based Balluff GmbH, has introduced new 2X extended range SteelFace sensors suitable for harsh sensing environments. The offering includes PNP N/O and NPN N/O versions in M8, M12 and M18 sizes. All sensors are also available with PTFE coated housings that repel slag buildup in welding applications. The SteelFace sensors’ features include one-piece gun drilled stainless steel 316L housings for corrosion and impact protection. The M12 double range version exhibits no loss of range when flush mounted in steel, while more expensive triple range models have noticeable reductions. Their long range characteristics, combined with PTFE coatings, give them long term survivability in tough weld cell applications. These new 2X extended range sensors further expand Balluff’s broad SteelFace line, which also includes ferrous, non-ferrous and long range 3X models. The sensors are suitable for a variety of jobs in machining, metal forming, welding, food preparation, or other harsh duty applications.
