Omron continues to lead the global industrial automation sector with its advanced sensor technologies, delivering high-performance solutions that ensure precision and reliability. The Omron E3Z series is widely trusted for applications in packaging, automotive, electronics, and conveyor systems where space-saving, robust sensing devices are essential.
The Omron E3Z-B61 2M is a reliable retro-reflective photo sensor that operates without MSR (mirror surface rejection) functionality, making it ideal for detecting standard opaque objects. It uses a 660 nm red LED light source and offers a stable detection range of 80 mm to 500 mm when used with the E39-R1S reflector. Designed for DC operation at 12–24 VDC, this model features NPN output and comes pre-wired with a 2-meter cable. It includes a one-turn adjuster for fine sensitivity control and built-in protection circuits against polarity reversal, output short-circuits, and mutual interference. With an IP67 protection rating and rugged PBT body, it withstands dust, water, shock, and vibration, ensuring long-term reliability in demanding environments.
The E3Z-B61 2M is best suited for detecting objects on fast conveyor belts, in packaging lines, or in assembly equipment where reliable mid-range sensing is required. Its narrow beam and fast 1 ms response make it ideal for detecting small to medium-sized components. The sensor simplifies installation and calibration, especially in compact machinery or tight enclosures.
