使用场景 APPLICATIONS

1 Industrial automation lines: Detect position of moving parts (conveyor belts, robotic arms, machine tools) to trigger stop/start/reverse actions

2 Packaging machinery: Control position of packaging materials or finished products for accurate sealing/labeling

3 Textile equipment: Monitor yarn spool or fabric roll positions to prevent overfeeding/underfeeding

4 Printing machines: Detect paper alignment or roller positions to avoid misprints or paper jams

5 Food processing equipment: Position sensing of processing components (cutting blades, mixing bowls) complying with RoHS standards

6 Material handling systems: Limit travel of cranes, lifts, or hoists to ensure safe operation within defined limits

注意事项 PRECAUTIONS

1 Safety: Ensure proper grounding; do not touch charged terminals or disassemble while power is on; use protective gear; install fuse with1.5-2x breaking current; do not exceed rated load; avoid flammable/explosive environments; prevent foreign materials from entering; do not wire wrong terminals; avoid prolonged pressed state; do not drop; do not connect to two different power supplies

2 Environment: Indoor use only; avoid extreme temps, high humidity, vibration, sunlight, salty winds, cutting chips, corrosive gases; do not use in silicon gas environments; check stored switches over 1 year before use

3 Handling: Do not remove built-in switches; avoid excessive force on actuators/cables; follow correct adjustment procedures for actuators

4 Mounting: Follow recommended tightening torques (M4:0.8-1.2N·m; panel nut:2.94-4.92N·m); install in vibration-free locations

5 Wiring: Use AWG18 wire with M3.5 crimp terminals; wire with power off; install separately sold terminal cover for IP65; avoid direct wire connection to terminals

6 System Integration: Design dog/cam to avoid actuator shock; ensure sufficient ON time for relays; do not exceed actuator OT limit; align pin-plunger with dog movement

7 Maintenance: Periodic inspection/replacement; only certified professionals to install/maintain
