Proximity Photoelectric Switch

Product Details:

Through Beam Sensor with Built-in Amplifier
 
 WORKING PRINCIPLE  :
This consists of two devices, a light emitter and a light receiver. The light receiver device contains amplifier circuit which gives transistorised output. These two devices are kept apart facing each other. The transmitter sends pulses of light in the infra red range which are invisible to the human eye. The receiver device opposite to the transmitter receives these rays. On interruption of these rays by the target object, receiver gives a signal which is amplified and fed to output transistor.
·  ADVANTAGES
- Large sensing distance is possible as emitter and receiver are kept opposite to each other.
- Suitable for precise detection of large as well as small objects. Repeatability and indexing precision are not
    impaired even if the object surface or background is reflecting.
- Can be coupled directly to PLC.

Working Principle
This is a system which consist of one device and a reflector. The device contains emitter and receiver The rays emitted by the emitter are reflected by the reflector to the receiver. The electronic sensing of the object occurs when these rays are interrupted.

Advantages

• Easy assembly compared to the through beam type.
• Large active sensing range compared to diffused beam type.

Field of Application
This electronic sensors can be used where it is difficult to install Through Beam Sensors due to space constraint. Further, simple wiring makes it suitable where sensing objects are bigger in size. Thus these sensors are used for loop control in decoiler, edge detection in paper/sheet metal etc.

   WORKING PRINCIPLE

2. This device consist of a transmitter and a receiver together. This look alike Inductive Proximity Sensor and hence is also known as IR Proximity Sensor. The emitter emits Infra red rays which are reflected on the receiver through the object to be registered. In the use of these sensors, it is important to bear in mind the colour of the object. Light colour corresponds to the maximum distance and vice versa. In case of shiny object; the effect of surface of object is more important than the colour.

3. ADVANTAGES

   - Transmitter and receiver are housed in the same housing.
   - As the self reflection of an object is used for detection; Dark & Light marks can be distinguished.

4. FIELD OF APPLICATION

   These Sensors are particularly used for position sensing and counting of non metallic objects. It is also used for Bottle sensing, Label sensing, Level sensing, Height sensing, Plastic film sensing, Edge detection of paper or sheet metal etc.

Product Details:

These are photoelectric sensors having slot type construction with slot gap 20mm/50mm/120mm/220mm.

The transmitter & receiver are mounted on two limbs of sensor opposite to each other.

The transmitter sends pulses of light in the infrared range which are invisible to the human eye. The receiver opposite to the transmitter receives these rays. On interruption of these rays by the target object, receiver gives a signal which is amplified and fed to output transistor.
