The Omron EE-SPX301 is a compact grooved-type reflective photomicrosensor designed for accurate detection in tight industrial spaces. It features a 3.6 mm slot width and uses a modulated light source for stable sensing with reduced ambient interference.
This sensor operates in Dark-ON mode and provides an NPN voltage output with a maximum load current of 80 mA. Its connector-type design ensures quick installation and easy maintenance. A red LED indicator on the body helps users monitor sensor status in real time. The power supply requirement ranges from 5 to 24 VDC, with peak current draw up to 50 mA.
Encased in a durable polycarbonate housing and rated IP50, the EE-SPX301 performs reliably in operating temperatures from -10°C to 55°C. It is ideal for use in precision automation tasks such as object presence detection, sorting systems, and compact machinery integration.
