The OMORN EE-SX771 is a compact photoelectric sensor designed for precise object detection in industrial automation. With an L-shaped form factor and 5mm slot width, it offers accurate through-beam sensing of small parts and moving components, making it ideal for encoder wheels, conveyor systems, and robotic assembly lines. The sensor operates on a 5–24V DC power supply, features NPN dark-on output (activates when light is blocked), and provides a fast 0.17ms response time for high-speed operations. Its infrared LED (940nm) ensures reliable performance in ambient light up to 1,000 lux, while dual indicators (red for output, green for stability) simplify setup. Technical specs include a 2m pre-wired cable, IP64 dust/water resistance, and short-circuit protection.
Built with a durable PBT housing, the EE-SX771 withstands vibrations (10–2000Hz at 100m/s²) and shocks (500m/s²), ensuring long-term reliability in harsh conditions. Its IP64 rating protects against dust and water jets, while a wide operating temperature range (-25°C to +55°C) supports use in extreme climates. The sensor’s slim 18x13x21mm dimensions enable flush mounting in confined spaces, and M6 threaded holes allow secure installation. OMORN’s ISO 9001 certification guarantees quality, with CE and RoHS compliance for global use. A 2-year warranty covers defects, reflecting confidence in its 100,000+ cycle lifespan.
The EE-SX771 excels in AGV navigation, part counting, and safety interlocks, leveraging its 5mm detection range to identify objects as small as 2x0.8mm. Its pre-wired 2m cable and 3-pin connector streamline integration with PLC systems, reducing installation time. Customization options include cable extensions and output configurations, tailoring it to specific automation needs. Factory-direct pricing and technical support make it cost-effective for large-scale projects. Common use cases include material handling, packaging machinery, and semiconductor manufacturing, where its compact design and high precision optimize workflow efficiency.
