The detection of transparent, reflective and dark objects has always been an issue for your average infrared and vision-based process control sensor. To help alleviate this problem the clever people at SensoPart developed a solution.
BlueLight Photoelectric Sensors!
Transparent, glossy, curved, sloping and deep black products have always been difficult to detect, especially if you have budgetary constraints. Sensors would suffer instability during detection and fail to detect properly leading to their eventual upgrade with a far more expensive product, OK if you can afford it!
Into the Blue
Blue light process control sensors offer much greater process stability than the usual red-light proximity sensors in challenging applications and are very cost-efficient. Difficult product detection scenarios can include a combination of several critical factors, such as black objects with a high gloss curved sloping surface and a wide detection angle, but even when faced with situations like this, the Sensopart Bluelight sensor range succeeds.
Why so Blue?
Increased detection efficiency is achieved with a higher intensity of blue light and the interaction of different light colours with the surface of the target object. The blue light emitted by these sensors is short-wave and doesn’t penetrate as deeply as a red-light sensor would, meaning that more light is reflected, a decisive feature when detecting poorly reflective and transparent objects.
Bluelight Photoelectric Sensor Features:
- Reliable detection of highly transparent or strongly light-absorbing objects
- Reliable detection at angles up to 90° (model dependent)
- World’s first blue light sensor with background suppression in subminiature format
- Absolute background suppression using SensoPart BGS technology critical background situations are no longer an issue
F10 Subminiature BlueLight Photoelectric Fixed Focus Sensor with Background Suppression
The ideal subminiature sensor, with precise fixed background suppression and a maximum scanning distance of 50 mm and an easy mount clamp. Dependable operation without a reflector even when faced with difficult surfaces and has a tamper-proof anti-misalignment design.
F25 Miniature BlueLight Photoelectric Fixed Focus Sensor with Background Suppression
Miniature in size but with a maximum scanning distance of 80 mm, with precise fixed ground suppression, fixed focus and an easy mount clamp. Features reliable switching behaviour when detecting light-absorbing and transparent objects.
F50 BlueLight Photoelectric Sensor with Background Suppression
A versatile photoelectric diffuse sensor with a large adjustable scanning distance of between 40 to 300 mm, that is easy to set using the indicator scale and features adjustable background suppression. Impressive performance on reflective and glossy backgrounds and connectivity is via a rotatable M12 plug with 4-pins.
F55 BlueLight Photoelectric Diffuse Sensor with Background Suppression
A power photoelectric diffuse sensor with very large adjustable scanning distance of between 3 to 1200 mm and adjustable background suppression. Exceptional performance on reflective and glossy backgrounds with reliable detection on angles up to 90 degrees. Connectivity is via an M12 plug with 4-pins.

(Blue)Lighting the Way
SensoPart’s BlueLight Photoelectric sensors are successfully being used in thousands of applications involving light-absorbing objects. Examples include detecting carbon fibre components in the automotive industry, or black, round plastic caps and metallic reflective components on a conveyor. The sensor achieves high process stability with transparent objects thanks to its instantaneous response at the respective maximum scanning range and the low hysteresis between the switch on/off point.
Photoelectric sensors like that SensoPart’s BlueLight range are certainly causing a stir in industrial automation and control world as a cost-efficient solution for replacing standard retro-reflective photoelectric sensors in challenging applications.
