Omron EE-SPX403N Infrared Photoelectric Sensor

The Omron EE-SPX403N Infrared Photoelectric Sensor is a compact optical sensing device that detects objects within a 13 mm range using infrared light, offering a precise, small-footprint option for tight spaces in automation and packaging equipment. It provides an NPN output and operates from a 12-24 VDC power supply with a current draw of 80 mA, enabling straightforward connection to standard PLCs, controllers, and control circuits without requiring unusual voltage rails. Made by Omron, a longstanding leader in industrial sensing, the EE-SPX403N combines reliable performance with a simple electrical interface, making it suitable for short-range detection tasks where space is at a premium and quick, repeatable switching is required in compact machinery and line-side equipment, and its compact footprint helps installation in recessed or limited-space locations. This sensor's infrared technology and fixed 13 mm sensing distance help reduce alignment concerns and simplify sensor replacement in small-footprint layouts.
