DSNU-12-125-P-A – Long-Stroke Compact Cylinder for Light-Duty Actuation
The DSNU-12-125-P-A pneumatic cylinder offers a 125 mm stroke length, providing extended linear motion in a compact, ISO-standard body. It features a 12 mm piston diameter, M6 male thread piston rod, and operates in double-acting mode — suitable for precise push-and-pull applications. With elastic cushioning at both ends, the cylinder absorbs energy smoothly, minimizing mechanical stress and improving cycle life.
Designed to ISO 6432 and CETOP RP 52 P standards, this model includes proximity switch support for position feedback, making it suitable for sensor-based control systems. The materials used — anodised aluminium for the cover and high-alloy stainless steel for the piston rod and barrel — ensure resistance to corrosion and compliance with RoHS and VDMA cleanroom standards. With a pressure range of 1.5 to 10 bar, and operating temperature from –20°C to 80°C, it’s built to perform reliably even in fluctuating shop-floor environments.
Applications of the DSNU-12-70-P-A Cylinder – Simple Yet Essential Motion
The DSNU-12-70-P-A finds its strength in compact, repetitive-motion setups where reliability matters more than high force. A common use case is light material handling, such as pushing or indexing components on small conveyors or trays. Its size and stroke make it suitable for clamping fixtures, automated test benches, and part positioning units in electronics or plastics manufacturing.
In packaging units, it is often used for tasks like gently pushing pouches or aligning cartons for sealing. In lab automation, this cylinder handles controlled sample movements without excessive force, ensuring delicate parts aren't damaged. Engineers also use it for activating safety doors, guide rails, or marking tools, where precise linear motion is required.
The model’s compatibility with proximity sensors enables smart cycle tracking and seamless integration with PLCs. This makes it a solid choice for engineers looking to improve process consistency without adding bulk or complexity. In short, the DSNU-12-70-P-A brings together precision, reliability, and ease of integration — exactly what junior and senior engineers alike look for in a pneumatic actuator.
