Sensor

For automation systems in industrial and commercial facilities, sensors are among the most critical components for monitoring conditions, detecting changes, and enabling intelligent control decisions. Sensors convert physical parameters such as temperature, pressure, proximity, position, and flow into electrical signals that automation systems can process and act upon. Electrical.com carries an extensive selection of automation sensors from all major manufacturers, including new, used, surplus, and re-certified options. These components are designed to meet the diverse needs of manufacturing automation, process control systems, material handling operations, and building management applications.
