Item A - Long Range Photo-electric Beams

Long range photo-electric beams have a range up to 500 feet.



What Is a Photoelectric Sensor?
Photoelectric Sensors detect objects, changes in surface conditions, and other items through a variety of optical properties.
A Photoelectric Sensor consists primarily of an Emitter for emitting light and a Receiver for receiving light. When emitted light is interrupted or reflected by the sensing object, it changes the amount of light that arrives at the Receiver. The Receiver detects this change and converts it to an electrical output. The light source for the majority of Photoelectric Sensors is infrared or visible light (generally red, or green/blue for identifying colors).

Fast Response Time
The response time is extremely fast because light travels at high speed and the Sensor performs no mechanical operations because all circuits are comprised of electronic components.
High Resolution
The incredibly high resolution achieved with these Sensors derives from advanced design technologies that yielded a very small spot beam and a unique optical system for receiving light. These developments enable detecting very small objects, as well as precise position detection.
Non-contact Sensing
There is little chance of damaging sensing objects or Sensors because objects can be detected without physical contact.
This ensures years of Sensor service.
Easy Adjustment
Positioning the beam on an object is simple with models that emit visible light because the beam is visible.




Item B - Short Range Photo-electric Beams

Short range photo-electric beams have a range up 100 feet.
