The Omron E3ZM-B66 is a precision-engineered retroreflective photoelectric sensor featuring an integrated mutual interference prevention (MSR) function. With a sensing range of 100 to 500 mm, it is optimized for the reliable detection of transparent materials like PET bottles. Powered by a 10 to 30 VDC supply, it uses a red LED (650 nm) light source and supports NPN output configuration with a 4-pin M8 connector, making it suitable for integration into compact automation systems.
This stainless steel photoelectric sensor is equipped with a teaching-based sensitivity adjustment, delivering fast 1 ms response time and excellent stability under varying lighting conditions. Three status indicators (operation, stability, and teaching) ensure accurate feedback and minimize commissioning time. Advanced protection featuresโsuch as short-circuit, reversed polarity, and reversed output polarity safeguardsโenhance overall reliability. It is specifically designed for sectors like food processing automation, where fast, accurate, and sanitary detection is critical.
Encased in a SUS316L stainless steel body with components made of PMMA, PES, and fluoro rubber, the E3ZM-B66 boasts IP67 and IP69K protection ratings, providing superior resistance to washdowns, dust, and mechanical stress. As part of the Omron industrial sensor series, this model combines durability with precise detection, making it a reliable choice for high-hygiene and high-speed applications.
