Pizzato Rope Pull Limit/Position Switch Mechanical Interlock (Industrial Switches)
Overview of Pizzato Rope Pull and Limit/Position Switches
Pizzato Elettrica is a renowned manufacturer of industrial safety switches, offering a broad selection of rope pull switches, limit switches, and mechanical interlocks designed for use in hazardous and automated environments. With durable metal housing and high ingress protection ratings, Pizzato switches are built for performance in the most demanding industrial settings.
Their rope pull switches and position switches are ideal for applications such as conveyor systems, automated machinery, and emergency stop installations. Designed to comply with EN ISO 13850 and EN 60947-5-1, these switches help safeguard personnel while maintaining operational efficiency. Pizzato’s rope safety switches provide fast shutdown capabilities over long spans, increasing reaction time and worker safety.
Key Features and Technologies
Mechanical Interlock Design
Pizzato’s mechanical interlock systems ensure safety by physically preventing unsafe operations. The use of separate actuators allows for flexibility in positioning, while robust contact mechanisms guarantee reliable actuation.
Contact Block and Switching System
Each switch features a precision-engineered contact block that offers consistent response under various loads. These blocks are available with silver contacts and can be configured with multiple contact options, including closer contacts, to suit your control circuit requirements.
Metal Housing Durability
Pizzato switches are encased in rugged metal housings, ensuring resistance to impact, vibration, dust, and moisture. Most models meet IP67 standards or higher, making them suitable for harsh industrial environments.
Rope Pull Emergency Operation
The rope pull safety switches act as emergency stop systems across long conveyor belts. A simple pull of the rope triggers the internal contact system, immediately disconnecting power and initiating safe shutdown procedures. Some models include a push lock turn reset or switch with reset mechanism, requiring a deliberate operator action to resume machine operation, enhancing safety.
Foot Switch Compatibility
Several models integrate with foot switches for hands-free emergency stop functionality, enhancing operator convenience without sacrificing safety.
Wall Mount Flexibility
Pizzato offers wall mount options for easy integration into control panels, guard rails, or production line structures, ensuring secure and accessible switch installation.
Sensor Integration and Reflective Technology
In addition to mechanical solutions, Pizzato provides sensor-based technologies such as retroreflective sensors and reflective sensors for object detection, positioning, and automation safety applications.
Electrical Characteristics
Power Supply Options
Pizzato switches are available in a variety of configurations compatible with 24-240VAC/DC power supply systems. Whether you’re working with DC power supply setups, 50/60Hz power supply grids, or high-voltage AC configurations, Pizzato devices ensure consistent electrical performance.
Power Relay Integration
These switches are frequently paired with 24VDC power relays for seamless integration into safety circuits and PLCs, offering enhanced control and diagnostic capabilities.
Operating Voltage and Maximum Ratings
With a broad operating voltage range and clearly defined maximum voltage limits, Pizzato safety devices are engineered to perform reliably in diverse industrial power environments.
Disconnect Switch Functionality
Certain models incorporate disconnect switch capabilities, enabling mechanical isolation of power during service or in the event of a fault. Some versions are built as polycarbonate enclosed motor disconnect switches, providing additional electrical insulation and protection for motor circuits, further improving safety and compliance.
Thermal Magnetic Protection
Select devices include thermal magnetic miniature protection features, helping to guard against overcurrent and short-circuit faults in low-voltage control systems.
Industrial Applications
Pizzato’s rope pull switches, position limit switches, and mechanical interlocks are used extensively in:
- Conveyor systems
- Packaging machinery
- Food and beverage lines
- Material handling
- Automated manufacturing equipment
Whether used as part of an emergency stop system or for precise position detection, these safety switches provide reliability and compliance in safety-critical environments.
With modular design, configurable contact blocks, and options for separate actuator installation, Pizzato offers one of the most comprehensive solutions for industrial machine safety. Their offerings also include accessories such as direct handles and grey covers to suit various installation preferences and visual safety indicators.
