使用场景 APPLICATIONS

1 Industrial conveyor belt systems: Detect goods position or stop belt at specific points

2 Machine tools(lathes, milling machines): Control moving part stroke to prevent overtravel

3 Packaging machinery: Position packaging materials or finished products for accurate sealing/labeling

4 Textile machinery: Limit movement range of yarn guides or fabric rollers

5 Printing equipment: Detect paper presence or adjust printing plate position

6 Automated assembly lines: Check component presence or confirm assembly step completion

7 High-temperature industrial environments: Suitable for areas up to150°C(e.g., heat treatment peripherals, high-temperature drying lines) leveraging phenolic enclosure heat resistance

注意事项 PRECAUTIONS

1 Must properly ground the switch to avoid electric shock

2 Do not touch charged terminals during operation

3 Do not disassemble or touch internal components when powered on

4 Wear appropriate protective gear during installation/maintenance

5 Connect a fuse with1.5-2 times the product's breaking current(or10A IEC60269 type gG/gL for EN/IEC/GB rated use)

6 Ensure load current does not exceed rated value to prevent damage or burnout

7 Do not use alone in flammable/explosive gas environments

8 Prevent foreign materials(cable scraps) from entering during wiring

9 Avoid long-term pressed state to prevent component deterioration

10 Do not store/use in extreme temp fluctuations, high humidity(condensation-prone), strong vibration, direct sunlight, salty winds, cutting powder, oil, chemicals, or corrosive gases(H2S, SO2, NH3, HNO3, Cl2)

11 For outdoor use, add protective equipment

12 If silicon products are nearby, use surge suppressors to prevent contact interference

13 Follow wiring guidelines: Use AWG18 wires with M3.5 nylon insulation crimp terminals

14 Adhere to specified mounting torque values

15 Only certified professionals perform installation/maintenance

16 Conduct periodic inspections and replace as needed
