An analog proximity sensor is a sensing device that detects an object and provides a continuous output signal based on how close the object is to the sensor. Unlike a standard proximity sensor, which only gives ON or OFF signals, an analog proximity sensor outputs a variable voltage or current that changes smoothly with the distance of the target. This allows the sensor not just to detect presence but also to measure position or displacement with high accuracy.
Analog proximity sensors are widely used in applications where precise distance measurement or positioning is needed. For example, in assembly and automation systems, they help measure the exact position of metal parts. In material-handling and packaging lines, they ensure accurate spacing between components. They are also used in robotics, machining centers, and inspection systems where continuous distance feedback is required for smooth operation.
Omron analog proximity sensors are designed for reliable performance and excellent linearity, offering stable analog outputs such as 0–5V, 0–10V, or 4–20mA. These sensors can measure small changes in distance with high precision, even in dusty, oily, or high-vibration environments. Omron’s designs make them ideal for industrial automation systems where accuracy, repeatability, and durability are important.
An analog proximity sensor is especially useful when gradual control or feedback is needed instead of simple detection. It helps maintain consistent quality, improves machine accuracy, and enables smarter automation by converting position changes into measurable electrical signals.
