The Autonics BJX3M-PDT is a high-performance Long Distance Photoelectric Sensor designed with retroreflective sensing and a polarizing filter for enhanced accuracy. Offering a 3m sensing distance, it detects opaque objects as small as Γ75mm. Powered by a red LED (660nm), it ensures stability under strong ambient lighting up to 11,000lx. With a rapid 1ms response, selectable Light ON/Dark ON modes, and adjustable sensitivity, it is tailored for precision-driven industrial automation.
This sensor operates on a 10β30VDC supply with just 30mA consumption, integrating smoothly with PLCs via NPN open collector output. Its IP65-rated polycarbonate housing and polymethyl methacrylate lens provide dust and moisture protection, while the wide operating temperature range of -25Β°C to 60Β°C ensures reliability in harsh environments. The Γ4mm, 2m cable connection and included reflector (MS-2A) support fast installation and alignment, making it convenient for engineers and maintenance teams.
Applications of the BJX3M-PDT include carton detection on conveyors, presence verification in packaging, gate position monitoring, and quality inspection in logistics and FMCG industries. Engineers value its long sensing range, durability, and stable operation, while students and trainers use it to understand the fundamentals of industrial sensors. Wholesalers, dealers, and distributors recommend it for industries requiring long-term stability and consistent performance.
The Autonics BJX3M-PDT strengthens the Photoelectric Sensors lineup with its balance of efficiency and rugged build. Whether for new automation projects or system upgrades, this sensor ensures accuracy and reduces downtime. For complete details, visit the Autonics Photoelectric Sensors page.
