Omron is a global leader in sensing and automation technologies, offering reliable and innovative solutions for factory automation. Known for their precision engineering and quality, Omronβs photoelectric sensors are widely used across manufacturing, food packaging, and electronics industries. Compact designs like the E3T series are especially trusted for space-constrained environments where reliability and consistent performance are essential.
The Omron E3T-SL12 2M is a limited reflective photoelectric sensor designed for short-range object detection. It features a red LED light source with a sensing range of 5 to 15 mm, making it ideal for precise detection in tight spaces. The unit comes with a pre-wired 2-meter cable and operates on 12 to 24 VDC. Its NPN output and Dark-ON mode ensure easy integration with existing control systems. The sensor consumes only 20 mA and responds in just 1 ms, allowing for fast and accurate object detection. Built with a durable polybutylene terephthalate body and denatured polyarylate lens, it carries an IP67 rating for protection against water and dust.
The E3T-SL12 2M is best suited for detecting small parts, edges, or objects on assembly lines, especially where installation space is limited. It performs well in compact jigs, automated stations, and miniature machinery. Its precise and stable sensing ensures reduced false detections and reliable operation even in demanding conditions.
