Optoelectronic distance sensors from Balluff support you in positioning, material flow control or fill level detection as well as in many other applications. Whether in the automotive industry, factory automation and logistics or in steel construction, you can achieve noticeable increases in productivity and specifically avoid errors through reliable distance measurement. Different, partly adjustable measuring ranges from 20 mm to 20 m and versions with and without background suppression are available for this purpose. Our sensors, which work non-contact and therefore wear-free according to the triangulation principle or time-of-flight technology (TOF), use red light or laser. They are housed in durable plastic or metal housings and have analog current and voltage outputs as well as digital serial or IO-Link interfaces. Our optoelectronic distance sensors are available in protection classes IP65/67 and IP69K, making them suitable even for harsh environments.
