Diffuse sensors with background suppression

Product selector

These sensors are suited for the reliable detection of objects against a background. Available in a variety of special designs, the series offers robust and efficient solutions, even for tricky applications such as the detection of extremely dark objects or objects with colored structure as well as objects with openings.

HRT 25B / HT 25C - Standard models (LED and laser)

Product selector

The diffuse sensor with background suppression in red light, laser or infrared reliably detects very dark or structured surfaces. It combines large ranges with an above-average function reserve and short response time. An especially powerful long-range model, e.g., for intralogistics applications with operating range greater than 2 m is also available.

  • Universal application with M4 threaded sleeves and degree of protection IP69K
  • Reliable with materials/surfaces having low reflectance
  • Mechanical adjustment of range
  • Background suppression with very small black/white error in a lot of light spot variants
  • Additional status LEDs on the front side of the sensor

HRTR 25B / HT 25C - Extra large and small light spots

Product selector

The diffuse reflection sensor with background suppression and large light spot (model XL) is well suited for the reliable detection of containers with openings, such as meshed containers. The S model with focused light spot is particularly well suited for the reliable detection of objects with glossy surfaces and surfaces with colored structure. This makes it the sensor of choice for complex applications, such as in packaging technology.

  • Optimized light spot for reliable detection of meshed containers (model XL)
  • Reliable positioning on glossy, metallic surfaces with openings (e. g. slide bolts)
  • Focused light spot for the reliable detection of objects with glossy and inconsistently structured surfaces (model S)
  • High switching frequency and short response time for detection of fast events
