Fargo Controls, Inc.
Proximity Sensors for Metal Detection Fargo Controls offers inductive proximity sensors for detecting the presence of metallic objects. Inductive proximity sensors detect the presence of metallic objects. Their operating principle is based on a coil and high frequency oscillator that creates a field in the close surroundings of the sensing surface. The presence of metal in the operating area causes a change in the oscillation amplitude. This change is identified by a threshold circuit, which changes the output of the sensor...

Fargo Controls, Inc.
Capacitive Proximity Sensors Fargo Controls - Capacitive sensors are used for non-contact detection of metallic objects & nonmetallic objects (liquid, plastic, wooden materials and so on). Capacitive proximity sensors use the variation of capacitance between the sensor and the object being detected. When the object is at a preset distance from the sensitive side of the sensor, an electronic circuit inside the sensor begins to oscillate. The rise or fall of such oscillation is identified by a threshold circuit that drives... (read more)Browse Capacitive Proximity Sensors Datasheets for Fargo Controls, Inc. -
