The Omron EE-SPZ401-A is a compact retroreflective photomicrosensor with an integrated lens and a sensing range of up to 200 mm when used with the E39-R1 reflector. It uses infrared light for stable object detection, especially in environments with reflective surfaces or low contrast targets.
This model features a Light-ON mode and delivers a NPN voltage output with low residual voltage—making it ideal for PLC-based automation systems. The sensor’s efficient design consumes only 15 mA on average and peaks at 50 mA, providing energy-efficient operation. A red LED indicator on the body offers real-time visibility into sensing status.
Built with a polycarbonate case and lens, the EE-SPZ401-A provides IP50 protection and reliable operation in temperatures from -10°C to 55°C. Its compact build and connector-free wiring make it suitable for use in packaging lines, material handling, and automated inspection systems.
