About Inductive Proximity Sensors

Inductive proximity sensors are noncontact proximity devices that set up a radio frequency field with an oscillator and a coil. The presence of an object alters this field and the sensor is able to detect this alteration. An inductive proximity sensor comprises an LC oscillating circuit, a signal evaluator, and a switching amplifier.  The coil of this oscillating circuit generates a high-frequency electromagnetic alternating field. This field is emitted at the sensing face of the sensor. If a metallic object (switching trigger) nears the sensing face, eddy currents are generated. The resultant losses draw energy from the oscillating circuit and reduce the oscillations. The signal evaluator behind the LC oscillating circuit converts this information into a clear signal.  The measurement of proximity, position and displacement of objects is essential in many different applications: valve position, level detection, process control, machine control, security, etc.


Products & Services Related to Inductive Proximity Sensors

Capacitive Proximity Sensors
Capacitive proximity sensors detect the presence or proximity of a target using capacitive technology.
Eddy Current Proximity Sensors
Eddy current proximity sensors and switches detect the proximity or presence of a target by sensing the magnetic fields generated by a reference coil.
Hall Effect Position Sensors
Hall effect position sensors are non-contact devices that convert energy from a magnetic field into an electrical signal. They use the Hall effect, a voltage caused by current-flow in the presence of a magnetic field.
Hall Effect Proximity Sensors
Hall effect proximity sensors are used to detect the proximity, presence or absence of a magnetic object using a critical distance.
Magnetoresistive Linear Position Sensors and Switches
Magnetoresistive linear position sensors and switches have a linear resistance output signal representing the distance an object is from a reference point.
Photoelectric Sensors
Photoelectric sensors use emitters and receivers to detect the presence, absence, or distance of target objects.
Ultrasonic Proximity Sensors
Ultrasonic proximity sensors use reflected or transmitted ultrasonic waves to detect the presence or absence of a target component.
