The Omron EE-SPW311 is a long-distance through-beam photomicrosensor designed for precise object detection up to 1 meter. Featuring a compact design and modulated light source, it ensures stable performance in challenging environments.
This model operates in Dark-ON mode and delivers an NPN open collector output with a residual voltage of 0.8 V at 100 mA. It supports connector-type wiring and includes a red LED indicator for clear status feedback. With a low 20 mA current draw per unit and a 100 mA max load, it fits seamlessly into power-sensitive applications.
EE-SPW311 is built with a durable PBT case and polycarbonate lens, offering IP60 protection. It withstands vibrations, shock, and a wide temperature range (-10°C to 55°C). Ideal for packaging lines, sensing automation, and component positioning, this sensor is a reliable part of Omron’s industrial detection range.
