Optical Sensors are important components of electronic control systems in modern equipment and industrial automation applications. In particular, photoelectric sensors display efficient performance in fields requiring the detection of liquid, solid or gas and shapes and distances. Among them, the E3S-5LE41 Optical Sensor is a two-tones, polarized retro-reflective photoelectric sensor with a sensing spot diameter of 2mm and a detection distance of 1 m. This product offers robust performance with an IP67-rated protective enclosure and three-layer reverse shielding.

The core of the E3S-5LE41 Optical Sensor is a photoelectric diode. When light from the built-in light source illuminates an object, which is reflected by the target and enters the receiver, the photoelectric diode is turned off and a light-off signal is triggered. The cavity lenses of the light source and receiver are adjusted to 90 degrees, and only the light reflected by the target is detected. This makes the detection of the target more accurate.

The application field of the E3S-5LE41 Optical Sensor ranges from automotive components to food packaging. For instance, it is used in these industries as a photoelectric switch, pulse stop device, line following device, and edge detector. In the circuit, the output is connected to a microcontroller, connected to an amplifier circuit for driving, and connected to the external system for control.

The working principle of the E3S-5LE41 Optical Sensor starts when it sends out beam light. When the light spot of the emitter is reflected by the object, it is re-emitted back to the receiver. At this time, the receiver generates electric signals according to the intensity of the light. If the light intensity reaches the set level, the photo-electric switch is turned on, the output changes from off to on, and the response is short and reliable. Otherwise, the intensity of the light decreases and the output turns off.

Furthermore, the E3S-5LE41 Optical Sensor is designed with a high sensing accuracy, temperature and vibration compensation capability and optical polarization technology, so that it can easily detect the position of the target without being affected by environmental changes. It also has a reliable structure, low power consumption, and wide voltage range to ensure long usage.

To conclude, the E3S-5LE41 Optical Sensor is a versatile photoelectric switch for industrial and automotive use. It is designed to detect objects in a wide range of conditions with precision and robustness. Its working principle leverages a simple design; where it emits and receives light in a retro-reflective setting that triggers a signal when an object breaks the light spot. This makes it reliable for use in a range of applications from food packaging and automotive components to line following and edge detection.
