W8 Inox

The W8 INOX is a miniature product family, especially for applications in harsh ambient conditions. The high-quality IP 69K stainless steel housing (1.4404/SUS316L) in combination with high-performance PPSU and PEEK plastics make these sensors suitable for a broad range of applications. In addition to a highly visible LED light spot, the W8 INOX includes M3 threaded mounting holes that reduce mounting time. These compact, lightweight sensors provide maximum resistance to harsh wash down environments in the food and beverage industry. The four models – through-beam, retro-reflective, energetic and background suppression (BGS) – provide reliable, high-performance solutions for harsh environments.
