Overview
The ifm Electronic OGH500 is a diffuse reflection photoelectric sensor with integrated background suppression, designed for precise object detection in industrial automation environments. Operating at 10-36 VDC with a 15-300 mm sensing distance and 1000 Hz switching frequency, the OGH500 delivers reliable, non-contact detection without the cost and complexity of through-beam transmitter/receiver pairs.
Key Features
- Diffuse-type sensing with background suppression eliminates false triggers from reflective surfaces
- M18 threaded barrel housing fits standard sensor mounting brackets
- M12 connector for quick disconnect and reliable field replacement
- PNP output with selectable Light-ON or Dark-ON switching logic
- IP67 protection rating for wet and contaminated industrial environments
- Red LED indicator for visual status feedback during operation
- Wide supply voltage range (10-36 VDC) simplifies integration into mixed-voltage systems

Typical Applications
The OGH500 excels in parts handling, packaging line object detection, material separation, and conveyor-based sorting applications. Its background suppression capability makes it ideal for detecting parts on reflective surfaces or within confined spaces where through-beam sensors are impractical. Common uses include bottle detection, label verification, carton orientation sensing, and parts presence confirmation in assembly lines.
