Fargo Controls proximity sensors are of the highest quality, durability & repeatability to meet today's tough industrial requirements. We provide a wide range of proximity sensors to meet all types of applications.

Proximity sensors detect the presence of an object without physical contact. Typical applications include the control, detection, position, inspection and automation of machine tools and manufacturing systems. They are also used in the following machinery: packaging, production, printing, plastic molding, metal working, food processing, etc.

OPERATING PRINCIPLES
How do proximity sensors work?

Inductive & Capacitive
Their operating principle is based on a high frequency oscillator that creates a field in the close surroundings of the sensing surface. The presence of a metallic object (inductive) or any material (capacitive) in the operating area causes a change of the oscillation amplitude. The rise or fall of such oscillation is identified by a threshold circuit that changes the output state of the sensor. The operating distance of the sensor depends on the actuator's shape and size and is strictly linked to the nature of the material (Table 1 & Table 2.). A screw placed on the back of the capacitive sensor allows regulation of the operating distance. This sensitivity regulation is useful in applications, such as detection of full containers and non-detection of empty containers.
