    Photoelectric Sensor With Built-in Small Amplifier [E3Z]

    OMRON

    [Features]· Photoelectric sensor standard, reliable assurance of 1 million units per year.· Industry's top class built-in amplifier: with detection range: Mutual interference prevention filter is available for transmission type (red light source type, detection distance 10 m) (sold separately).· Install mutual interference prevention function in various reflective type· Detection distance 30 m (response time 2ms) long distance transmission type is also available.· Guaranteed low-temperature operation that can be used in freezing warehouse: Enlarge the operating ambient temperature range to-40 to +55 °C (main model connector type).· Sensor I/O connector with high durability even in low temperature environment (PUR cable) was also made.· Improvement of coincidence between optical and mechanical axis: Since the deviation between the optical and the mechanical axis is kept within ±2.5° the optical axis aligns by simply fitting it to the mechanical axis (transmission type, regression reflection type).· Protection of sensor even if wiring mistake occurs output reverse protection function is carried (we add diode for reverse connection protection to output line).· In addition, we use burnable polyethylene wrapping paper.

                                FAQ Photoelectric Sensors

                                Question: What is the range of Detection Distance available for the sensors?
                                Answer: The range of photoelectric sensor detection distance available for the sensors depends on the type of photoelectric sensor and the object being detected.

                                Here are some examples of typical detection distances for different types of photoelectric sensors:

                                1. Retroreflective photoelectric sensors: Retroreflective photoelectric sensors have a detection distance of up to 30 meters or more.
                                2. Diffuse photoelectric sensors: Diffuse photoelectric sensors have a detection distance of up to 10 meters or more.
                                3.Through-beam photoelectric sensors: Through-beam photoelectric sensors have a detection distance of up to 100 meters or more.

                                However, it is important to note that the detection distance of a photoelectric sensor can be affected by a number of factors, such as the environment, the object being detected, and the sensor's settings.
                                Question: How do Photoelectric Sensors Work in Various Industrial Applications?
                                Answer: Photoelectric sensors are widely employed in various industrial applications to detect objects, monitor processes, and ensure safety. For example,
                                1. Object Detection: In automation, photoelectric sensors identify the presence or absence of objects on conveyor belts, enabling precise control of material or parts flow.
                                2. Distance Measurement: By measuring the time it takes for light to bounce back from an object (time-of-flight), these sensors provide distance data for robotics, positioning, or anti-collision systems.
                                3. Level Sensing: In tanks or hoppers, these sensors monitor fluid or material levels, ensuring timely refills or preventing overflows.
                                4. Label Detection: In packaging, they verify the presence and alignment of labels, ensuring accurate product labeling.
                                5. Edge Detection: Photoelectric sensors maintain alignment in printing and paper industries.
                                6. Counting: They tally products on assembly lines, helping manage inventory and quality control.
                                Question: What are the Different Types of Photoelectric Sensors and How to Choose the Right One?
                                Answer: Photoelectric sensors come in various types, and choosing the right one depends on your specific application. Here are the key types:
                                1. Through-Beam Sensors: These consist of a separate emitter and receiver, offering high accuracy over long distances. Ideal for precise object detection, such as conveyor systems.
                                2. Retro-Reflective Sensors: Use a reflector to bounce light back to the sensor. Suited for medium-range applications like door control systems and parking barriers.
                                3. Diffuse Reflective Sensors: Combine emitter and receiver in one housing. They are versatile for close-range object detection, suitable for packaging and assembly lines.
                                4. Polarized Sensors: Use polarized light to minimize glare and reflections, making them great for glossy or reflective surfaces, like label detection on shiny packages.
                                Question: What are the Key Features to Consider When Selecting a Photoelectric Sensor?
                                Answer: When selecting a photoelectric sensor, consider the following key features to ensure it suits your application:
                                1. Type of Sensor: Choose from through-beam, retro-reflective, diffuse reflective, polarized, depending on your specific needs.
                                2. Detection Range: Ensure the sensor's range covers the distance at which objects need to be detected within your application.
                                3. Environmental Conditions: Consider factors like temperature, humidity, and the presence of dust or contaminants. Select a sensor designed to withstand the environment it will operate in.
                                4. Output Type: Determine if the sensor's output (e.g., NPN, PNP, ) is compatible with your control system for seamless integration.
                                5. Shape and Size: Ensure the sensor's physical dimensions and shape fit within the available space in your application.
                                6. Object Characteristics: Consider the material, size, color, and surface characteristics of the objects you need to detect, as this can impact sensor performance.
                                7. Power Supply Compatibility: Ensure the sensor's voltage and power requirements match your machine's power supply.
                                Question: How to Install and Maintain Photoelectric Sensors for Optimal Performance?
                                Answer: Installation:
                                1. Mounting: Securely mount the sensor in a stable position, ensuring it aligns properly with the objects to be detected.
                                2. Alignment: Carefully align the emitter and receiver (for through-beam and retro-reflective sensors) to establish a clear line of sight.
                                3. Protection: Shield sensors from harsh environmental factors using protective enclosures or covers when necessary.
                                4. Cabling: Use high-quality, shielded cables to minimize interference and ensure reliable connections.

                                Maintenance:
                                1. Regular Cleaning: Periodically clean the sensor's emitter and receiver to remove dust or dirt that may affect performance.
                                2. Calibration: Perform routine calibration to maintain accuracy, especially in critical applications.
                                3. Cable Inspection: Check cable connections for tightness and any signs of wear or damage. Replace damaged cables promptly.
                                4. Environmental Checks: Monitor the operating environment for changes in temperature, humidity, or other factors that may affect the sensor.
                                5. Record Keeping: Maintain records of maintenance activities, including cleaning, calibration, and cable replacements.
                                6. Replacement Schedule: Consider implementing a schedule for periodic sensor replacement, as sensors may degrade over time.
