- Electromechanical Switches – Electromechanical switches are often used as components within control systems to start, stop, or change the operation of machinery. They can be integrated into control panels or directly onto equipment to initiate specific actions or sequences.
- Limit Switches – An Electromechanical Switch that acts as a Sensor to detect the physical movement and position of machinery parts, typically initiating or stopping an action by opening or closing an electrical circuit when a specified limit is reached.
- Hall Effect Controls – Hall effect controls utilize the Hall effect, which is the production of a voltage difference (the Hall voltage) across an electrical conductor when a magnetic field perpendicular to the conductor’s surface is applied while current is flowing through it. These controls typically consist of Hall effect sensors, magnets, and associated electronics. Otto Controls’ Hall effect controls leverage this principle to provide precise and reliable sensing solutions for industrial equipment applications
Other CAN Solutions – Controller Area Network Solutions facilitate the seamless transmission of data between various components of industrial equipment
