Rotary Limit Switches

Rotary limit switches are electromechanical devices used to control movement in construction and industrial equipment. Installed on winches or gearboxes, these devices monitor and precisely manage rotations and positions of various systems, ensuring safety, reliability and steady operation.

How rotary limit switches work

The operation of a Ravioli rotary limit switch is based on an internal mechanical system composed of cams and electrical contacts. Through its drive shaft, the device is connected to the motor or system to be controlled. Once a preset number of rotations is reached, the cams actuate the internal contacts causing the equipment movement stop or change.

Applications of rotary limit switches

Limit switches are used wherever precise control of movement and position of rotating mechanical components is required. Thanks to their flexibility, Ravioli limit switches are widely used in construction and industrial lifting systems, in automatic roll up door control, ventilation and feeding systems in farming, logistics and industrial handling systems, and in renewable energy production sites, both wind and solar.

Features, advantages and customised solutions

The Ravioli rotary limit switch range offers a high level of customisation, making these products suitable for multiple industrial sectors. Key advantages include easy installation, simple configuration, high precision of actuation, wide range of gear ratios extensive mounting accessories. These products ensure protection degree up to IP66, high resistance to mechanical stress, resistance to acids, oils and UV radiation. The range consists of 4 series of limit switches and allows to apply 2 to 12 safety contacts and adjustment cams with different profiles ranging from 20 to 180 degrees of intervention. Each limit switch allows safe control of multiple analogue positions and integration of sensors such as incremental or absolute encoders with outputs in voltage, current or digital signals which help in optimising space and reducing wiring costs.

The design flexibility and features that limit switches are equipped with allow them to respond precisely to the application needs of each customer, ensuring optimal integration within existing systems.
