Functions

Emergency equipment stop – by pulling the rope from any direction, the switch activates instantly and interrupts the electrical circuit or sends a signal to the control system.
Rope deviation detection – the integrated mechanism allows detection of rope tension or deviation changes, enabling early identification of a dangerous situation.
Explosion-proof construction – due to its special design, the switch can be used in hazardous industrial zones where flammable gases or dust may be present.
Resistance to harsh conditions – IP67 protection and a robust metal housing ensure reliable operation in dusty, humid, or vibrating environments.
Long service life – designed for more than 100,000 operating cycles, making the switch suitable for continuously operating industrial systems.

Applications

For industrial equipment and production lines: The switch is often used on conveyor belts, transport lines, warehouse automation systems, and factory equipment where the ability to quickly stop equipment is required.
For storage and logistics systems: In large warehouses or logistics centers, a safety rope can be installed along the transport line so that workers can activate emergency stop from any point.
For electricians and automation specialists: The device can be easily integrated into control panels, PLC systems, or safety circuits, making it suitable for industrial automation projects.
For engineers and designers: Used when designing safety systems for industrial facilities where a reliable mechanical emergency stop system is required.
For maintenance technicians: An excellent solution for upgrading old conveyor systems or increasing the safety level of existing equipment.

Advantages

IP67 protection – resistant to water and dust
Explosion-proof construction – suitable for hazardous areas
Robust aluminum and stainless steel housing
Long service life – more than 100,000 cycles
Fast emergency response when the rope is pulled
Wide operating temperature range (-40°C to +50°C)
Reliable solution for industrial safety systems

Disadvantages

Requires correct rope installation and tensioning
Usually used in industrial facilities, therefore it may be too complex for household users
Maximum current is 5A, therefore it is often used together with contactors or control relays
