The CSL-RD mini pneumatic actuator from Aventics Corp., Lexington, Ky., was designed with hygiene in mind. For example, its tube/cover was made using roll-in geometry, which reduced the width of gaps between housing components and eliminated sharp edge and grooves. There’s also a new scraper without an undercut. All of these prevent accumulation of dirt.
The stainless-steel housing, plastic slide bearing, and other components are built with materials that resist corrosion and harsh chemicals, an advantage for parts exposed to frequent washdowns. The cylinders also meet ISO 6432 standards. These characteristics make the cylinder well-suited for the food and drink companies, as well as the chemical industry.
The cylinders also come with sensor holders that are easy to assemble and attach. Designed to fit ST4 and ST6 series sensors, they are made of light, high-strength plastic that resists all common industrial cleaners. The cylinder also has pneumatic cushioning that can be adjusted using a hex-headed screw designed to minimize dirt accumulation.
The cylinder can withstand temperatures from –20° to 80°C with PUR seals or –10° to 150°C with FKM seals. The cylinder’s pressure range is 1.5 to 10 bar. Bore sizes are 16, 20, and 25 mm, and strokes can be up to 1,200 mm.
