How Rotary Encoder Works

 

What is Rotary Encoder?

A rotary encoder also called a shaft encoder is a position sensor that is used to detect the angular position and speed of electrical signals. They process the signals based on the rotational movements i.e clockwise or anti-clockwise movements.

Angular position: As the shaft rotates around the center axis, an angular position exists for each location along the path of travel.

Classification of Rotary Encoder

There are many types of rotary encoders that can be classified based on output signal or sensing technology.

 

The most common type:

Absolute: In this current position will be known as soon as the power is applied.

Incremental: This encoder immediately reports change in the position without reporting track of the absolute position.

How Rotary Encoder Works?

The inside of the encoder consists of an evenly spaced disk. And a series of electrically charged pads are placed around the outer portion of the disc. On top of these pads there are 3 contact pins – A, B, and C as given below:

                    Diagram to understand how rotary encoder works

 

Pin A and B are set of fixed position contacts called the clock and data line which are 90 degrees out of phase.

When the disk starts rotating, pin A (clock) and pin B (data lines) make contact with pin C (the electrically charged pad). This further creates square wave output signals as shown in the above figure.

These output waves can also be used to find the angular position by counting the number of pulses of the signal.

The positioning of pin A and pin B is in such a way that it makes the shaft turn clockwise or anti-clockwise and based on the direction of the shaft the travel direction is determined.

Check out the diagram for a simplified explanation of the working and classification of the rotary encoder:

Types of Terminal Blocks

 

What is a Terminal Block?

Terminal Block is a connector used to wind up a single wire and connect it to another system or circuit. There are wide range of terminal blocks are available in different sizes, shapes, and ratings but they always terminate a single wire only. Terminal blocks are very suitable for semi-permanent connections. And they are commonly used in domestic wiring and industrial wiring.

Types of Terminal Blocks

1. Screw Terminals:

Screw terminals are the most used connection methods in this method wires will be inserted into the terminal and clamped with the use of a screw. These terminals are commonly used in domestic as well as commercial wiring where voltage and current demands will be moderate. Over-tightening the wire while fixing can damage the inserted wire/cable which further may cause unreliable and dangerous connection.

2. Barrier Terminals:

Barrier terminals are similar to screw terminals and use screws to hold the cables although they have more than one termination point for multiple cables and have small barriers between every terminal. Some Barrier terminals also have a small lid and an enclosure to protect the cabling. These are commonly used in domestic wiring and also in high voltage applications which requires arcing and short circuits prevention.

3. Push-fit terminal blocks:

Small spring-loaded shafts in Push-fit terminal blocks allow the cable to enter the terminal block in one direction and hold it in place without allowing it to leave. This technology depends on a spring having enough force to keep the wire in contact with the conductive body. The disadvantage of these terminals is it’s not designed to be reused and do not have removing shaft. This makes repairing work a difficult task and sometimes the whole terminal needs replacing.

4. Pluggable terminal blocks:

Pluggable terminal blocks have a cable entry to allow the connection of a wire or cable and also a plug output that can be connected to a socket. This is very useful for connections which are expected to be removable for inspection purpose or for servicing purpose.

 

These are the 4 primary types of terminal blocks although there is the number of terminal blocks are available in the market with different technologies and mounting options. Analyze your application area and future requirements thoroughly before deciding on which to buy.

Customized cable assemblies need cables with metallic electrodes that can efficiently transmit an electrical load during a product’s lifespan. If you choose the wrong type of conductor, rust or corrosion may occur. Cable conductors made of the wrong materials can also break or otherwise fail in the field.

That is the reason it’s essential to choose a perfect conductor material that can meet your application prerequisites, the natural conditions, and your electrical boundaries. Cost is a thought, as well. You’ll likewise need to pick solid or strong connectors and indicate the quantity and their sizes. NS Engineers are the best customized cable assembly manufacturers in Bangalore.

MATERIALS FOR CONDUCTORS

Silver, copper, and gold are more electrically conductive than aluminum, zinc, nickel, metal, and bronze. Uncovered copper is additionally more electrically conductive than tinned copper. However, conductivity alone is infrequently the main prerequisite. Links utilized in high-stickiness conditions or close to saltwater are powerless to erosion. Exposed copper isn’t the most ideal decision here, so tinned copper is frequently utilized all things considered. In conditions with high help temperatures, nickel-plated copper gives more noteworthy oxidation obstruction than uncovered copper. Silver is the most conductive metal of all, but at the same time, it’s more costly than other expected decisions.

SOLID CONDUCTORS VS. STRANDED CONDUCTORS

Stranded conductors comprise of more slender wires that are curved together to go about as a bigger director. Solid conductors have a solitary metallic center all things being equal.

Stranded conductors are generally more costly than solid connectors; notwithstanding, Stranded conductors are additionally more adaptable, simpler to introduce, and typically have a more drawn out life expectancy.

Solid conductors commonly cost less and are more tough and solid than Stranded conductors. Solid conductors are better at forestalling electronic impedance, but on the other hand, they’re more unbending. In the event that the links in your custom link get together are liable to visit movement, untimely wearing can happen.

CONDUCTOR SIZES relationship with NUMBER OF CONDUCTORS

Cables can have one conductor, a couple of conductors, or a few hundred conductors. Generally, the number of conductors required determined by the function of the number of circuits required to connect and whether extra wires are required.

Conductor sizes are chosen based on the application’s capacity load and actual necessities.
