Description
The OMRON E3T Series Small Cylindrical Photoelectric Sensors are compact, high-precision sensors designed for space-constrained and high-reliability applications. Featuring multiple mounting styles (M2, M3, and small cylindrical), stainless-steel construction options, and a wide range of sensing methods, the E3T Series enables stable detection in demanding environments such as rechargeable battery manufacturing lines. The lineup supports through-beam, retro-reflective, diffuse-reflective, limited-reflective, and BGS-reflective sensing, with Red or Infrared light sources and Light-ON/Dark-ON operation. Extensive accessories allow flexible installation, precise alignment, and long-term reliability.
