Series 28

Intelligent sensor technology for the entire world of automation

The 28 series sensors are reliable, powerful photoelectric sensors that are predestined for many standard detection tasks in materials handling, packaging technology and machines for special applications. They feature high operating ranges and many technical highlights such as the brightVision® light spot for easy alignment and are available at an incredibly price/performance ratio.

Advantages and benefits at a glance:

  • Best service - Convenient online product selector for easy comparison and selection of the right product using technical features; Global production concept guarantees worldwide availability of products, even on short notice; Global price guarantee increases planning security in worldwide markets; Competent customer service center and technical support aid in the selection of suitable products and the right implementation;
  • Very simple operation - Large brightVision®  light spot without blind area for easy alignment and reliable detection of even the smallest objects; Bright yellow/green LED status display for easy function state check; A2LS active suppression of extraneous light for reliable detection and low susceptibility to ambient and stray light for easy and convenient sensitivity adjustment;
  • Fexible integration options - Sturdy, warp-resistant, plastic housing in IP 67 for sensor use even in rough industrial onments; Two complementary switching outputs for either light or dark switching operation; Inovative fastening concepts for flexible mounting and easy alignment; Large temperature range from -40 to +60 °C makes possible a broad range of applications.

Mounting and handling just the way you want them

This series features three mounting options and can there- fore be used very flexibly in all installation situations. Choose between simple, universal mounting via an M18 thread on the front or bottom of the device or very robust screw fitting on the through holes. The pockets for the mounting nuts integrated in the housing also serve as anti-rotation protec- tion and considerably simplify mounting.
