SICK  announced the launch of the C4000 Palletizer Advanced and the M4000 Standard in IP 69K housings for washdown applications. In addition, the C4000 Micro in an IP 69K housing is now available in lengths up to 1800 mm and has an increased scanning range of up to 14.5 m. Designed for use in washdown applications, corrosive and other moist environments, these safety light curtains offer a reliable safeguarding solution that reduces customers’ cost of ownership. A smooth plastic PMMA housing and corrosion-resistant, stainless steel end caps and mounting brackets eliminate bacteria growth when food accumulates in grooves. Due to the rugged IP 69K housing, these safety light curtains are resistant to various chemicals, such as acetic acid, hydrochloric acid and sulfuric acid. The C4000 Micro and M4000 Standard are ideal for washdown applications in dairy, chemical and meat processing industries. The M4000 Standard IP 69K features two 4-beam versions and one active/passive version with a scanning range from 0.5-4 m. The C4000 Palletizer Advanced IP 69K, which features a 30 mm resolution with a protective height of 1,050 mm, provides access protection in applications requiring transportation of goods and materials.
