In terms of performance, encoders are divided into two types: incremental and absolute.\r\n\r\n### Incremental encoder\r\n\r\nIn this type of encoders, a pair of transmitter and receiver LEDs and a calibrated disc (black and white or perforated) are used, and the calibrated disc is placed between the transmitter and receiver sensor. During the rotation of the graduated disc, the signal between the transmitter and the receiver is cut off and connected successively, and we will have a set of pulses at the output. By counting the number of pulses, the amount of rotation and displacement can be calculated.\r\n\r\nThe more the number of pulses, the more accurate the movement calculation will be.\r\n\r\n\r\n\r\n**[Click here to view Atonix products.](https://www.automation24.ir/product/list/search/?manufacturer_id=3&sort=order-desc)**\r\n\r\nBy counting the number of encoder pulses, the amount of movement or rotation of the shaft can be measured. But if we have a row of output pulses, it is not possible to detect the direction of rotation. Therefore, the encoders must have a second set of pulses, which is separate from the primary pulse.\r\n\r\nAlso, a single pulse that represents the rotation time of a complete cycle of the encoder shaft is also produced by the encoders. The first set of pulses is known as A, the second set is known as B pulse, and the third unit pulse is known as Z pulse. \r\n\r\nIf there is a set of pulse A before pulse B, the encoder rotates clockwise (clockwise), and if pulse B is earlier than pulse A, the shaft rotates counterclockwise (clockwise).\r\n\r\nEncoders are made to produce different number of signals according to usage needs. The most widely used rotary encoder is Atonix in 3 signal and 6 signal types. In the three-signal model, the supply voltage is 24V DC and the encoder has 3 wires. In model 6, the power supply voltage signal of the encoder is 5V DC and the encoder has three pulses *A, *B, and *C in addition to the pulses A, B, and Z, which are exactly the opposite of the primary pulses. That is, when the pulse A is at the logical 1 level, the *A signal is at the dotted zero level.\r\n\r\n\r\n### Absolute encoder\r\nA major problem in incremental encoders is that the count of pulses must be stored in a counter, and if there is a malfunction in the counter for any reason, the encoder loses its position. In the incremental encoder, the zero point of movement will not be clear. To solve this problem, absolute encoders were created that will always know the position they are in and the distance from the starting point (zero point). The disc used in these encoders consists of a number of equivalent grooves, which rotate certain codes.

The light sent by the transmitter is spread directly in the environment, and if it hits an obstacle, it is reflected and changed by the receiver. Using the coefficient table below, the performance interval will be determined. \r\n\r\n### Reflective:\r\n\r\nIn this type of sensors, the transmitter and receiver are installed next to each other and inside a case, the light sent by the transmitter is spread in the environment and is reflected directly to the receiver by hitting a reflector (mirror). If there is an obstacle in this path, the light does not reach the receiver and the sensor detects the obstacle.\r\n\r\n### Two-way:\r\n\r\nIn this type of sensors, the transmitter and receiver are located separately from each other and must be installed facing each other. The light sent by the transmitter is emitted in the environment and received by the receiver. If there is an obstacle in this path, the light does not reach the receiver and the sensor detects the presence of an obstacle in front of it.\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n**[Click here to view Atonix products.](https://www.automation24.ir/product/list/search?keywords=&in_description=1&category_id=0&inc_subs=1&manufacturer_id=3&pfrom=&pto=)**\r\n\r\n## Optical sensors are divided into two types, Light on and Dark on, in terms of operation.\r\n\r\n**Light on:** In the normal state where there is no obstacle in front of the sensor, the output of the sensor is inactive, and if the sensor works, the output changes from inactive to active (N.O output).\r\n\r\n**Dark on:** In the normal state where there is no obstacle in front of the sensor, the output of the sensor is active, and if the sensor works, the output changes from active to inactive.

There are many push buttons in the market with different models and different shapes and mechanisms. Push buttons actually perform a function when pressed by the operator. Push buttons can be momentary, that is, they act as soon as we press it and it returns to its original state if we let go of it, or it can act in such a way that it acts by pressing it and in It remains in the same position and returns to its first position by being compressed again.\r\n\r\n## Push buttons in terms of color:\r\n\r\nPush buttons are also made in different colors, each of these colors represents a type of function. For example, red color is used to step the system and green color is used to start or start the car. This feature prevents the operator from making mistakes while working with these keys.\r\n\r\nAlso, a series of push buttons in red color have bigger heads than other push buttons, which are called mushroom keys in the industry and are used as emergency chassis in the system. This type of mushroom push buttons is designed in two ways, with keys and simple, for use in different places. Depending on the limitations of the system, the push buttons are made of plastic or metal, which have a simple or waterproof function available in the market.\r\n\r\n## In terms of performance status:\r\n\r\nIn order to show the status of some of the push buttons to the operator, a light is also installed on them, which the operator will notice if the light turns on. \r\nThat this key has worked.\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n[**Click here to view Pars Fanal products.**](https://www.automation24.ir/product/list/search?keywords=&in_description=1&category_id=0&inc_subs=1&manufacturer_id=64&pfrom=&pto=)\r\n\r\n## Things to consider when buying push buttons:\r\n\r\n1.

Relays consist of two parts that are completely independent from each other. The first part, which is actually the relay coil, which can exist independently of the relay base or in a compact form, and the second part of the relay, which is the same as the relay base.\r\n\r\nToday, relays are widely used in the industry, relays are mostly used in control circuits, almost all devices used in the industry, either openly or covertly, use relays. is One of the advantages of the relay is that by using it, you can get a high power output with a very low power. In other words, it can be said that the relay is also considered as an amplifier because the input with low current and the output with high current can be received from it. Depending on the type of construction, relays have 2 bases for feeding the coil and one or more COM blades (common), one or more closed blades (NC) and one or more open blades (NO).\r\n\r\n One of the important applications of relays can be in using the PLC output path. Because the PLC outputs that exist as relays inside the CPU, it is possible that if they are directly connected to the consumer, they will be defective due to current draw. As a result, the output of the PLC is connected to the coil of an external relay and the consumer is stimulated by the blades of the external relay. The good thing about this is that if something happens to the consumer, the external relay is damaged, in which case the relay can be easily replaced, but if the PLC\'s internal relay is faulty, it cannot be repaired easily.\r\n\r\n## Parts of the relay:\r\n\r\nspring\r\nCoil to magnetize the blades\r\nContact blades\r\niron core\r\nNote) Relays used to be mostly made electromechanically, but today, with the advancement of technology, electronic relays, including SSR relays, etc., have also been made.\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n**[Click here to view Kaken products.](https://www.automation24.ir/product/list/search/?manufacturer_id=6&pageItems=120)**\r\n\r\n## Things to know when buying a relay:\r\n\r\nRelay coil excitation voltage and current\r\nTolerable voltage of contacts\r\nThe number of blades\r\nAppearance of the relay
