The Banner Q20PDXL: 78151 delivers long-range sensing performance using a diffuse mode that reaches up to 1500 mm, making it one of the most capable sensors in its class. It uses a visible red LED beam for enhanced target detection and stability, especially when reflective surfaces are not available. The sensor is housed in a rugged thermoplastic rectangular body, built to withstand industrial stress and maintain accuracy in dusty, wet, or chemically exposed environments. Rated for both IP67 and NEMA 4X, the Q20PDXL is protected against water ingress and corrosion, making it suitable for food-grade facilities, outdoor automation, and heavy machinery setups. This model includes a 2-meter cable connection and operates on a 10β30 V DC power supply with PNP discrete outputs. A potentiometer allows local adjustment of sensing sensitivity, helping engineers fine-tune performance on-site based on surface reflectivity or object material. With a response time of 0.8 ms and repeatability of 155 Β΅s, it ensures precision triggering even in fast-paced automation lines. The acrylic lens and built-in LED indicators simplify maintenance and setup, while a 100 ms power-up delay helps prevent false signals during startup. Operating effectively between -20Β°C and 60Β°C and up to 95% relative humidity, the Q20PDXL sensor is trusted by OEMs and integrators across diverse industrial sectors. For complete specifications, consult the official Banner Q20PDXL datasheet.
Applications of Q20PDXL: 78151 - Banner 1500 mm Long Range Diffuse Sensor
The Q20PDXL: 78151 is ideal for automation scenarios where extended sensing distance is a must. In automotive plants, it helps detect car body panels or large components moving along conveyors. In palletizing and logistics systems, the sensor accurately senses cartons or totes from a distance without the need for reflectors. For material handling and sorting, its ability to detect over 1.5 meters makes it a reliable choice for triggering gates, actuators, or alert systems. Maintenance teams prefer the Q20PDXL for its easy setup, durable construction, and ability to perform consistently in fluctuating temperatures and high-humidity zones common in Indian manufacturing environments. Its long range and adaptability also make it suitable for replacing multiple short-range sensors, simplifying system design while improving reliability.
