Series 3

Sensor solutions for nearly any application – Series 3B

Compact, versatile, user-friendly, robust

Series 3B from Leuze electronic offers a range of unique features and the largest variety of functions in this performance class of all competitors on the market.
In addition to large operating ranges and improved performance reserves for reliable object detection, even in dusty environments or with high align- ment tolerances, technologies such as Active Ambient Light Suppression (A²LS) or “brightVision®” for easy handling and fast commissioning or device models with homogenous pin-point light spot are characteristic of Series 3B.
The diverse range of models make these sensors ideal for a wide variety of applications, for example in mounting and handling technologies, in the conveyance of extremely small containers as well as in printing and pack- aging  technologies.
