Laser sensors are used for detecting presence based on position or light intensity. Benefits include long range, a visible beam spot, and precise detection. These devices have a small footprint and have options to withstand the most demanding environments.
Self-contained Photoelectric Sensors
Conventional miniature photoelectric sensors typically do not provide long term reliability due to weak structural design and unstable operation. In order to solve these issues, operation stability features including background suppression and automatic cross talk prevention have been combined with a heavy duty metal housing to create a better miniature photoelectric sensor.
In industrial automation, the large majority of general purpose photoelectric sensors are made of plastic. While this design is adequate for certain environments, harsher industrial environments require that these sensors be frequently replaced due to damage. By combining a metal housing with reliable detection capabilities, KEYENCE has developed a durable photoelectric sensor that will provide lasting detection in the harshest of environments.
The PZ2 series micro-optical sensors with built-in amplifiers are small, waterproof, and have the ability to detect transparent objects.
