What are the applications of Limit Switch?

Image
This is a switch that is operated by the motion of a machine part. They are used to detect the presence of an object when it reaches a selected or desired point.  It is an electromechanical device that consists of an actuator which is mechanically linked to a set of contacts. The limit switch regulates the electrical circuit that controls the machines moving parts by preventing the travel of an object past a predetermined point in the mechanism. The switch activates when an object makes contact with the actuator and by doing so either breaks or forms an electoral connection. Most limit switches fall under two categories: 1- Maintained Contact Switch It means that when it is switched on, it stays on until you push it off (labeled On-Off-On). 2- Momentary Contact Switch It means that when you push on, it stays on while still pressing/holding on it but upon releasing its springs back to its maintained position (labeled On (or Off). How does a limit switch work? The swi...

What are the different types and components of PLC?

Image
PLCs stand for Programmable logic controllers and are digital computers for automating electromechanical processes such as lighting fixtures, control of machinery at the factory assembly lines or amusement rides. They are used in many machines and automotive and other industries. They are majorly designed for multiple outputs and input arrangements, elevated temperature range, noise immunity and vibration, and impact immunity. They are lightweight, rugged devices functioning without air conditioning, fans or electrical filtering. Different Components of Programmable Logic Controller There are three major PLC components , these are: 1. Processor 2. Power Supply 3. Input/output (I/O) section 1- The Processor The processor acts as the intellect of the PLC system. It’s a solid-state device designed to perform many functions in machine tool, process control function and machine tool. Formerly, relays, convectional electromechanically devices and associated wiring executed...

Five things to know before buying Encoder Online

Image
Have you considered buying an encoder for the automation processes in your industry? Are you confused because you do not know which encoder to choose? Well, cheer up; you are reading just what you need. You will learn the essentials on the subject matter, “how to buy an encoder.” For the sake of context, there may be a need to clarify which encoder is being referred to in order for the writer and reader to be on the same page. Basically, an encoder is anything that converts data from one format to another. Bearing this definition in mind, an encoder can be a program, transducer, an appliance, or even a human. The transducer kind of encoder is the focus here. So, take your mind off the other examples of encoders. Why is an encoder important? It is essential because, in systems where machines are in constant motion, and machine components are constantly changing positions, there is a need for standardization and accuracy. An encoder can help you achieve this. But, which encoder do...

Things to know before buying Electrical Switches Online

Image
Purchasing electrical equipment online is said to be more efficient than buying directly from the stores. When purchasing online, the buyer can have adequate time to look at the ratings and reviews that the product has already earned from other customers. The customer is also able to evaluate the comments made by other customers concerning the equipment, who have purchased or bought it before. Moreover, they can determine whether the dealer is genuine or not, by interacting with other customers on the business platform. It is imperative to take a quick review of the available comments and ratings on the product before rushing into buying the product. This paper looks into the various considerations that customers should look into when purchasing electrical switches online. What are the things to know before buying Electrical Switches Online?  One of the questions that a customer should ask themselves is whether the switch is the original product that has been manufactured b...
