Compact magnetic proximity switch designed for precise cylinder piston position detection in pneumatic systems. Features shock-resistant construction with glass fiber-reinforced housing and gold-plated reed contacts for reliable switching. The reverse polarity protection and surge suppression ensure stable operation in electrically noisy environments.
- Position feedback in ISO cylinder automation systems
- Tooling machine safety interlocks
- Packaging equipment cycle counting
- Injection molding machine mold position detection
- Automated conveyor belt sorting systems
Installation guidelines:
Mount sensor parallel to cylinder axis with 0.5-1mm gap from magnet carrier.
Use M5 mounting screws (max torque 0.8N·m). Maintain 10mm clearance from
ferrous materials to prevent magnetic interference. Test LED indication
during commissioning.
Do NOT use in strong magnetic fields
(>80kA/m) or near welding equipment. For tandem cylinder applications,
maintain ≥30mm spacing between adjacent sensors.
