Integrated mounting slots enable tool-free stroke limiter adjustment. Compatible with auto switches (e.g., SME/SMT series) for position feedback.

Ideal for:
  • Precision material handling in SMT equipment
  • Jig positioning systems for PCB assembly
  • Labeling machine actuation with variable product sizes
  • Semiconductor wafer transfer mechanisms
  • Pharmaceutical blister packaging machines
Operation tip: For optimal performance, maintain lubrication with ISO VG32 hydraulic oil mist in the air supply (1-2 drops/m³). Avoid side load exceeding 15N. Stroke adjustment should be performed at 0.3MPa or lower pressure.
