A sensor is a detection device that can convert non electric changes in physical parameters such as temperature, humidity, light, etc. into another physical parameter, such as current, voltage, etc. Sensors are widely used in science and technology, from space exploration to deep-sea exploration, and are used everywhere.
Inductive sensor
Inductive sensors can detect metal objects and are mainly composed of three parts: 1 Oscillator 2 Trigger circuit 3 Output circuit.
After the power is turned on, the oscillator begins to oscillate and generate a specific current. The electromagnetic field generated by the oscillating coil is concentrated on the sensing surface of the sensor. When a target object made of conductive material approaches the sensing surface, eddy currents are generated inside the target object, consuming the energy of the oscillator and causing attenuation of the oscillating circuit. The amplitude of the oscillator decreases, and once it reaches a certain amplitude, the subsequent trigger circuit activates, generating a switch output. The characteristics of the inductive sensors produced by our company are:
- The variety is complete and can reach thousands.
- Excellent quality, designed and produced according to European standards.
- The sensing range is from 0.6-150mm.
- The protection function is complete, and in special circumstances, it will not cause damage to the sensor.
- The highest protection level can reach IP69K.
- Sensors can be customized according to the user's usage requirements and environment.
