Many kinds of sensors can detect plastic bottles or glass...

Photoelectric sensors are a popular sensor type for solving many applications, but, depending on the application, using light can sometimes have its disadvantages.

Pepperl+Fuchs offers a wide variety of functional safety products that include photoelectric safety sensors. We offer single-beam safety sensors, light grids, and light curtains. It is important to know the difference as the cost varies and safety standards must be met.

Unique photoelectric sensors for edge monitoring

Moving machine parts, closing edges of doors and gates, and even automated guided vehicles (AGV) all have the potential to cause workplace injuries. Health and Safety regulations require that workers be protected from preventable injuries. But without the proper protection in place, worker safety can be at risk. One way to provide this protection is by machine safeguarding.

When it comes to determining which type of light grid is best for your application, there are a few questions to consider:

After a recent altercation with an older, legacy light grid, perhaps the better question is: How intelligent are you?

Automation light grids exist in many forms and offer solutions to applications from simple to complex. With sizes ranging from small to large, and with resolutions from fine to coarse, nearly every sensor manufacturer offers a light grid.  

Compared to single beam sensors, light grids offer more detection coverage over a defined area.
