Type of Sensor should I use

What type of sensor triggers actions when sensor and its target are directly looking at each other.

“Directly looking at each other” condition (sensor and it’s target) is for preventing sensors from reacting to other targets that will be in close proximity (about 70mm (3 inches) apart).

There are 3 or 4 pairs of sensor-target sets operating at about 70mm (3 inches) between sets.

Distance between each sensor and its target is about 600mm (24 inches).

There are many metal and non-metal parts that are not to be considered target (sensor should not react to them). Each sensor should respond to its designated target only.

Many thanks in advance for help.

You can use Infrared (IR) Sensors (Active or Reflective). Active IR sensors emit infrared light and measure the reflection of that light when it strikes a target. Reflective sensors are designed to detect the presence of a specific target when it’s within the sensor’s range and line-of-sight.

Many many thanks.

This sounds to be a solid step forward. I will buy a few pieces, get started, and reach out again along the way.

Thanks again.
