Why Choose the WAGO 750-635 Digital Impulse Interface Module?
The WAGO 750-635 is a specialised digital impulse interface module designed for the WAGO I/O System 750 and 753. It connects magnetostrictive linear position sensors that use a start/stop measurement interface, enabling accurate position detection in industrial automation and motion control applications.
After the controller sends a read pulse to the sensor, the sensor returns a time-delayed impulse. The delay time is proportional to the measured distance, allowing the controller to determine the exact position of the magnet along the sensor rod. The module processes this signal and stores the measured position data directly in the process image of the fieldbus controller. :contentReference
The interface uses RS-422 differential signalling to ensure reliable communication between the sensor and the controller even in electrically noisy industrial environments. This makes the module suitable for precision position measurement in automation systems such as robotics, production lines and hydraulic positioning equipment. :contentReference

High-Precision Position Measurement for Automation Systems
Magnetostrictive position sensors are widely used in industrial machinery to measure linear movement with high precision. These sensors provide non-contact measurement of piston or actuator position in hydraulic cylinders, production equipment and process automation systems.
The WAGO 750-635 integrates these sensors directly into distributed PLC architectures. By converting start/stop impulse signals into precise digital position data, the module enables real-time monitoring and control of linear positioning systems across industrial automation networks. :contentReference
