Overview
The SMC CDG1TA50-65 is a compact, reliable double-acting pneumatic cylinder from SMC’s proven CG1 series. With a 50mm bore and 65mm stroke, this actuator delivers consistent force and control for automated motion applications. The integrated auto-switch (magnetic piston detection) enables position sensing without external sensors, reducing wiring and component count in motion control systems.
Key Features
- Double-acting cylinder design with bidirectional pressure control
- Integrated auto-switch for reliable position detection and feedback
- 50mm bore diameter for smooth, controlled linear motion
- 65mm stroke length — compact form factor suitable for space-constrained installations
- Stainless steel rod and durable aluminum body construction
- ISO/CETOP ported — direct compatibility with standard pneumatic manifolds and valve blocks
- Female rod end available as standard; bracket and pivot options available separately
- Fine-adjustable auto-switch position for precise stop detection
