High-performance miniature sensor with blue light for all types of detection tasks

Thanks to its large switching distance and two switching outputs, the new BlueLight miniature sensor FT 10-BHD from SensoPart is suitable for a wide range of applications. And yet the sensor has extremely compact dimensions.

SensoPart has expanded its range of BlueLight sensors with the FT 10-BHD miniature diffuse photoelectric sensor with background suppression. With its compact size of only 21 x 14 x 8 mm, the sensor nevertheless has unique performance characteristics. Not only does it have the largest range on the market, 150 mm for white/grey and 120 mm for black, but also the scanning range is adjustable instead of a fixed focus. In addition, the miniature BlueLight sensor has two independently adjustable switching outputs

Use of second switching output

In other sensors, a second switching output is often used for cable break detection and permanently set to "antivalent". Although this option exists with the FT 10-BHD, it is possible to use the second output for other functions, for example to specify a second detection window. Thus, not only the presence of the object is detected, but also whether it is at an angle to the detection plane. In the case of two different objects, the sensor can distinguish whether both objects are present, just one, or none at all. As the second output is IO-Link compatible, it can also be used to set sensor parameters or retrieve diagnostic data, while the first output ensures fast data transfer.

Detect-All mode for stable object detection

"Detect-All" is a highly reliable operating mode for checking the presence of parts. The FT 10-BHD is taught in using a reference object (e.g. the background) around which a switching window is set. This eliminates a blind zone that would otherwise be several millimetres. The sensor can then detect changes in the distance to the taught-in reference and can, for example, distinguish objects of different heights.

The energy value is also evaluated, making it possible to detect larger deviations in contrast or colour. The sensor, which can detect any difference from the learned reference, thus still reliably switches when the emitted light is reflected by a difficult object, for example a metal point or a wavy object.

Red light vs. blue light

Thanks to the blue light spot, a stable and reliable detection process is possible, even with highly light-absorbing and shiny objects. Where conventional red light sensors reach their limit, the Blue Light sensor from SensoPart offers the solution. For example, a shiny black mobile phone screen is still reliably identified from angles of up to 40°, whereas a comparable red light sensor only allows a detection angle of 5-10°.

This high detection efficiency, combined with a detection range and functions that are exceptional for its class, make the FT 10-BHD a unique sensor. Ideal for a multitude of applications, for example when assembling and positioning objects. With its small dimensions, the sub-miniature sensor takes up little space and can be installed close to the process - even directly on a robot gripper.
