High-precision magnetic proximity sensor with reinforced anti-vibration design, featuring gold-plated reed contacts for stable signal transmission. The compact cylindrical body enables installation in confined spaces while maintaining 360° magnetic field detection capability. Shielded cable prevents EMI interference in industrial environments.
- Pneumatic cylinder position feedback (ISO cylinder compatible)
- Automatic door position verification systems
- Injection molding machine mold clamping detection
- Conveyor belt object presence sensing
- Hydraulic press stroke limit control
Installation guidelines:
Mount parallel to cylinder axis with ≤2mm air gap between sensor and magnet.
For optimal performance, maintain 5mm clearance from ferrous materials.
Use M3×0.5 mounting screws with 0.3-0.5N·m torque. Cable bending radius ≥15mm.
