Product features
Durability in extreme environments
Shock resistance: 50G mechanical shock resistance (in accordance with IEC 60068-2-27).
Corrosion resistance: salt spray test 500 hours (ISO 9227), suitable for harsh environments such as ships and mines.
Flexible installation
Provides M20 cable entry and standard bracket holes to support horizontal/vertical multi-directional installation.
The swing arm angle is adjustable (±90°) to adapt to different mechanical trajectories.
High load capacity
Directly control small motors and solenoid valves (no intermediate relay required).
Safety redundancy
Double contact design (NO+NC) can be used for safety circuit interlocking.
Visual status
Red/green mechanical indicator window for quick identification of switch status.
Typical applications
Construction machinery: Excavator arm limit position protection
Automated production line: Conveyor belt travel control
Lifting equipment: Crown crane end limit
Iron and steel metallurgy: Roller positioning of rolling mill
