High-precision mechanical stopper with integrated shock absorption, featuring dual-position magnetic sensor slots (G1/8 thread) for position feedback. The hardened piston rod (HRC 45-50) withstands lateral forces up to 250N. Optimized flow channels reduce air consumption by 15% compared to standard models.
- Workpiece positioning in automotive assembly lines
- Pallet stop mechanisms in conveyor systems
- Precision alignment in semiconductor handling
- Safety interlocks for robotic workcells
- Component retention in automated packaging
Installation guidelines:
Ensure perpendicular mounting surface (flatness ≤0.1mm) and use M6x1 mounting screws (torque 5.4-6.6N·m).
Maintain 0.5mm clearance between stopper face and target surface. Lubricate every 500km of cumulative travel.
Critical notes:
Not suitable for rotational applications. Maximum lateral offset tolerance: 0.3mm.
Requires 5μm filtered air with oil mist (ISO VG32 recommended). Avoid rapid pressure changes exceeding 0.5MPa/s.
