Triangulation Sensors from Pepperl + Fuchs – the Accurate Advantage

What are Triangulation Sensors?

Triangulation lasers or laser displacement sensors utilise a light source, typically a laser, a measured surface and a sensor to form a triangle. Triangulation sensors are typically used to measure the distance to an object quickly and accurately.

Using a laser or LED diode a concentrated light beam is projected on to an object and that light is deflected in all directions by the objects surface. Some of this deflected light is captured by the triangulation sensors receiver and any displacement of the object causes a displacement of the light captured. Displacement of an object can be accurately translated to a distance allowing these sensors to determine the position of both transparent or reflective objects.

High Speed, High Accuracy

Triangulation sensors are used for very accurate distance measurements and have high measurement speeds. Objects are detected independently of their surface structure, brightness and colour, as well as the brightness of the background.

Pepperl + Fuchs are worlds renowned for their outstanding range of sensor products, and their photoelectric triangulation sensor are no exception. These sensors are designed to function in demanding conditions and provide years of service.  We take a quick look at the Triangulation Sensor range from Pepperl + Fuchs extensive sensor range that you can buy today from Kempston Controls.

OBT15 and OBT 30 Sensors (BGS)

These capable triangulation sensors with background suppression are ideal for standard applications. A unique flat design for direct or bracket mounting, and 15 mm (OBT15) and 30 mm (OBT30) sensing ranges provide precision object detection almost irrespective of the objects colour. A highly visible light spot, even on dark materials, and a high degree of immunity to extraneous light and the ability to detect objects as small as 0.1mm means these sensors are suitable for a wide range of tasks.
