The OMORN E3T-ST13 is a compact photoelectric sensor designed for reliable object detection in industrial automation. Using a through-beam configuration with a 1m sensing range, it accurately identifies objects as small as 2mm in diameter, making it ideal for high-precision applications. The sensor operates with a fast 1ms response time and features PNP open collector output, ensuring seamless integration with PLC systems. Its red LED light source (650nm) offers stable performance in ambient light up to 10,000 lux, while dual indicators (orange for operation, green for stability) simplify setup and troubleshooting. Technical specs include a 12-24V DC power supply, 50mA load capacity, and multiple protection circuits (short-circuit, reverse polarity).
Built with a durable PBT housing and IP67-rated construction, the E3T-ST13 withstands dust, water immersion, and vibrations (10-2000Hz at 300m/s²). Its M2 threaded mounting allows flush installation in confined spaces, while the compact 18.5x9.5x7mm design minimizes space requirements. The sensor maintains performance across extreme temperatures (-25°C to +55°C) and humidity (35-85% RH), ensuring reliability in automotive manufacturing, logistics, and food processing. OMORN’s rigorous testing includes 1 million+ cycle durability and EMI shielding for interference-free operation.
Designed for flexibility, the E3T-ST13 excels in AGV navigation, conveyor sorting, and robotic positioning. Its light-on operation mode triggers outputs when a signal is detected, while pre-wired 2m/5m cables (with optional M12 connectors) streamline installation. OMORN offers customization options like infrared light sources and dark-on configurations to meet unique needs. Factory-direct pricing and a 2-year warranty make it cost-effective for large-scale projects. Backed by ISO 9001 certification, this sensor combines advanced technology with ease of use, empowering industries to optimize efficiency and safety in automated workflows.
