EE-SPX741 Photoelectric Proximity Sensor Introduction (English Version)
The EE-SPX741 series is an advanced non-contact photoelectric detection device utilizing infrared lightwave technology for reliable object presence sensing. Based on optical triangulation principle, this compact sensor (30×15×10mm) combines engineering plastics and metal composite housing, offering both structural durability and environmental resistance. Its modular design enables easy integration into various automation systems.
With millimeter-level detection accuracy, the sensor provides adjustable effective sensing range from 5mm to 300mm. The built-in temperature compensation module ensures stable performance across -25℃ to +70℃, while specialized optical filters effectively suppress ambient light interference. The dual NPN/PNP output configuration supports seamless integration with mainstream PLC systems, delivering maximum load current of 200mA. Three-color LED indicators provide real-time operational status and error code visualization.
This sensor excels in industrial automation applications including assembly line positioning, robotic arm motion verification, and conveyor belt material counting. Its fast response time (<1ms) meets high-speed production requirements, with IP67 protection rating ensuring reliable operation in dusty or oily environments. The optimized optical path design minimizes false triggers from specular reflections, making it particularly suitable for precision detection tasks in metal processing and packaging machinery.
Featuring a modular architecture, the EE-SPX741 allows maintenance operations like optical window cleaning or circuit board replacement without full disassembly. The wide voltage input (10-30VDC) with reverse polarity protection and overload protection enhances system reliability. Three optical modes (through-beam, retro-reflective, polarized retro-reflective) are available to accommodate diverse surface materials, ensuring consistent detection performance across various industrial applications.
