DSNU-20-100-PPS-A – Technical Specifications
The DSNU-20-100-PPS-A is a double-acting pneumatic round cylinder built to ISO 6432 standards, with a 20 mm piston diameter and 100 mm stroke length. Its key feature is self-adjusting pneumatic end-position cushioning, which automatically regulates deceleration at stroke ends, reducing wear and extending cylinder life—especially in fast-cycle applications. The unit operates at 1–10 bar, using clean compressed air per ISO 8573-1:2010 [7:4:4], and delivers 188.5 N of force on the advance stroke and 158.3 N on the return at 6 bar. It features a G1/8 pneumatic connection, M8 male-thread piston rod, and proximity switch compatibility for stroke position sensing. The materials used—high-alloy stainless steel for the piston rod and anodised aluminium for the cover—ensure moderate corrosion resistance (CRC Class 2) and make it RoHS-compliant and suitable for cleanroom Class 6 environments.
Applications of DSNU-12-70-P-A in Indian Industrial Systems
The DSNU-12-70-P-A is commonly used in machines that need precise, smooth motion with limited shock, such as product handling arms, sorting equipment, and inspection stations. Its self-adjusting cushioning makes it ideal for variable-speed operations, where manual tuning would slow down maintenance or reduce reliability. In Indian plants, this model helps improve efficiency by reducing vibration and preventing end-stroke impact. For engineering students, it offers an excellent hands-on learning experience in understanding how intelligent cushioning enhances pneumatic motion. Whether you're retrofitting an old system or designing a new one, the DSNU-12-70-P-A provides the right mix of performance, durability, and ease of use for real-world automation.
