The Omron EE-SPX743 is a compact grooved-type photomicrosensor designed for reliable object detection using a 3.6 mm slot-width through-beam configuration. It uses modulated infrared light to enhance detection accuracy and minimize interference from ambient light sources.
This sensor operates in Dark-ON mode and features an NPN voltage output with low residual voltage—just 1.0 V max. at 50 mA. It includes a red LED light indicator for quick visual status checks. With a current consumption of 15 mA (average) and peak up to 50 mA, it supports efficient operation in compact systems.
Built with a rugged polycarbonate body and connector-type design, the EE-SPX743 is rated IP50 and operates between -10°C to 55°C. It’s suitable for tight industrial environments, such as precision positioning, part presence detection, and small-scale automation tasks.
