Proximity Sensor Test Bench

Proximity Sensor Test Bench

Proximity Sensor Test Bench used to Perform Frequency Test of Various Proximity Sensor Specified from Manufacturer Under Standard Test Procedures to determine frequency of test samples.

Proximity Sensor

“Proximity Sensor” includes all sensors that perform non-contact detection in comparison to sensors, such as limit switches, that detect objects by physically contacting them. Proximity Sensors convert information on the movement or presence of an object into an electrical signal. There are three types of detection systems that do this conversion: systems that use the eddy currents that are generated in metallic sensing objects by electromagnetic induction, systems that detect changes in electrical capacity when approaching the sensing object, and systems that use magnets and reed switches.

Inductive: This type of sensor is used to detect nearby metallic objects. The sensor creates an electromagnetic field around itself or on a sensing surface.

Capacitive: This type of sensor is used for detection of metallic objects and nonmetallic objects.

Photoelectric: This type of sensor is used to detect objects. A light source and receiver are the main components of such sensors.

Magnetic: This type of sensor uses an electrical switch that is operated based on the presence of permanent magnets in a sensing area.
