The Omron Broad Slot-type Photomicrosensor EE-SPX303N offers reliable object detection with a wide 13 mm slot. It is designed to sense opaque objects as small as 2.2 × 0.5 mm, making it suitable for counting, edge detection, and part positioning in automated machinery. The infrared LED (940 nm) minimizes external light interference, supporting stable performance in factory lighting.
With its Dark-ON mode and NPN voltage output, the sensor operates at 12–24 VDC and supports load currents up to 80 mA. A red LED indicator confirms active detection, while protective circuits guard against polarity errors. Its minimum 100 Hz response frequency ensures fast and accurate readings during high-speed operations. Installation is simplified through a special connector, eliminating the need for soldering in compact control systems.
Housed in a lightweight polycarbonate shell and rated IP50, the EE-SPX303N endures harsh environments with vibration and shock resistance. It operates between -10°C and 55°C, ensuring durability in dynamic industrial settings. The EE-SPX303N is a precise, high-frequency sensor ideal for automation zones needing broad-slot detection.
