Photoelectric sensor with background suppression | 250mm | 32,5x20x12mm | 10-30VDC | NO/NC | NPN | 2m cable | ABS | Red light beam | IP67
Code: PSE-YC25DNBRPhotoelectric sensor with background suppression technology – a reliable and versatile device designed for object detection in various automation systems where high precision and resistance to external interference are required.
Thanks to its adjustable detection distance, compact square housing, and IP67 protection rating, it is suitable for both industrial production lines and home automation projects.Made of PC+ABS plastic with a PMMA lens, the sensor is durable, moisture-resistant, and highly protected against mechanical damage.
Its operation is based on the background suppression principle – the sensor accurately detects an object even when the background is bright or reflective.-

The sensor operates on the background suppression principle, allowing accurate detection of objects regardless of background or color.
It can distinguish an object from surrounding surfaces, making it ideal for detecting light, glossy, or semi-transparent objects.
The 5-turn adjustment knob allows easy sensitivity setting, while the LED indicators help monitor sensor status and signal strength.Applications
For home users or hobbyists: Suitable for object detection in workshops or personal automation projects.
For engineers / automation specialists: Ideal for robotics, production lines, conveyors, counting, or positioning systems.
For electricians / technicians: Compact design enables easy installation; clear LED indicators simplify diagnostics and maintenance.Advantages
Accurate background suppression
Adjustable detection distance
Fast response time
IP67 protection – dust and moisture resistant
Clear LED indicators – easy monitoring
Disadvantages
May require calibration when used with very transparent or black objects
