Omron is a globally recognized automation leader, offering innovative sensing technologies that improve reliability and productivity in industrial environments. Their E3T sensor family is designed for compact machinery where precision and size matter. Trusted across sectors like electronics, packaging, and pharmaceutical industries, Omron sensors deliver consistent performance in space-constrained automation systems.
The Omron E3T-SL24 2M is a square-type limited reflective photoelectric sensor with a detection range of 5 to 30 mm. It uses a visible red LED light source and operates on 12 to 24 VDC, consuming only 20 mA. The sensor provides PNP output and functions in Dark-ON mode. With a compact form factor, a pre-wired 2-meter cable, and a fast response time of 1 ms, it ensures high-speed detection in precise automation setups. The housing is made of polybutylene terephthalate (PBT) with a durable denatured polyarylate lens, giving the unit an IP67 rating for protection against dust and moisture.
This sensor is particularly suited for detecting small parts or labels in confined spaces, such as robotic pick-and-place machines, PCB handling systems, and high-speed inspection lines. Its limited reflective sensing method minimizes background interference, making it perfect for detecting low-profile or dark-colored objects close to the sensor.
