OMCH Brand proximity sensor switch is a displacement sensor with switching output, output mode have NPN, PNP, NO, NC and relay etc, it can be detect metal (such as iron, steel, copper) object, plastic, glass, wooden, water, paper, magnetic etc. transparent or opaque objects, can be connect with PLC, servo controller, frequency inverter, counter, controllers to achieve the purpose of automatic signal input control. It is widely used in the field of machinery, textile, light industry, papermaking, printing, packing industries. Meanwhile as per to market demand, we developed C series high class proximity sensor and normal class proximity sensor.
Inductive type Proximity Sensor can detect a metal object ( such as Iron, Steel, Copper etc)
Capacitive type proximity sensor can detect any object (such as glass, metal,water, oil, paper etc.)
The Proximity sensor is a kind of position switch that can be operated without direct mechanical contact with moving parts. When the object is close to the sensing surface of the switch to the action distance, it does not need mechanical contact and exerts any pressure to make the switch act, which will drive the DC electric apparatus or provide control instructions to the computer (plc) device.
The proximity sensor is a switch type sensor (i.e. non-contact switch), which has the characteristics of travel switch, micro switch and sensing performance at the same time, reliable operation, stable performance, fast frequency response, long application life, strong anti-interference ability, and has the characteristics of waterproof, shockproof, corrosion-resistant. The products are inductive proximity sensor, capacitive proximity sensor, Hall sensor, AC and DC type and magnetic switch.
The proximity sensor, also known as non-contact proximity switch, is an ideal electronic switching sensor. When the metal detector is close to the sensing area of the switch, the switch will be able to send out electrical instructions without contact, pressure and spark, and accurately respond to the position and travel of the moving mechanism. It is widely used in machine tools, metallurgy, chemical industry, textile and printing industries. In the automatic control system can be used as limit, counting, positioning control and automatic protection link

The Inductive proximity sensors consist of three main parts: an oscillator, a switching circuit and an amplified output circuit. The oscillator generates an alternating magnetic field. When the metal target is close to this magnetic field and reaches the induction distance, eddy currents are generated in the metal target, resulting in oscillation attenuation and even stopping. The oscillation of the oscillator and the change of the stopping of the vibration are processed by the post amplification circuit and converted into a switching signal, which triggers the driving control device, thus achieving the purpose of non-contact detection.
How to connect the proximity sensor to the equipment:
The wiring of the 3-wire proximity sensor: the red (brown) wire is connected to the positive terminal of the power supply; the blue wire is connected to the 0V terminal of the power supply; the yellow (black) wire is the signal and should be connected to the load. The other end of the load is connected in this way: for NPN type proximity switch, it should be connected to the positive side of the power supply; for PNP type proximity switch, it should be connected to the 0V side of the power supply.
The three-wire proximity sensor has an additional feedback wire, and the general proximity switch is DC with an operating voltage of 6V to 36V, or AC with an operating voltage of 36V to 220V.
The inductive proximity sensor wiring diagram:
The Proximity sensors are very wide range of switches that we can see it often in both industrial or life applications. In different applications, we use different types, so there are various types of proximity switches such as eddy current proximity sensors, capacitive proximity sensor, Hall proximity sensor, and photoelectric proximity sensor.
The Proximity sensors are widely used in aviation, aerospace, technology and industrial production. In everyday life, such as hotels, restaurants, garage doors, automatic hot air machines, etc. In safety and security, such as data files, accounting, finance, museums, warehouses, etc., they are usually equipped with various proximity switches and anti-theft devices. In measuring technology, such as length and position measurement; in control technology, such as displacement, velocity, acceleration measurement and control, a large number of proximity switches are also used.
