The text symbols and project codes in electrical technology are no longer needed to find them everywhere!
An electrical system or an electrical device usually consists of various basic components, components, components, etc. In order to represent these basic components, components, and components on electrical drawings or other technical documents, in addition to various graphic symbols, Some text symbols and project codes must also be marked to distinguish the different functions, states, and features of these devices and lines.
Text symbols usually consist of basic text symbols, auxiliary text symbols, and numbers. Letter code and function letter code for the type of electrical equipment, devices and components provided.
Basic text symbols can be divided into two-letter symbols and two-letter symbols.
(1) One-letter symbol One-letter symbol is an English letter that divides various electrical equipment, devices and components into 23 categories, each of which is represented by a special letter symbol, such as "R" for resistance class, "Q" Indicates the switching devices of the power circuit, etc., as shown in Table 1-6-. Among them, "I" and "O" are easily confused with the Arabic numerals "1" and "0", and are not allowed to be used, and the letter "J" is not used.
Table 1-1 Single-letter symbols commonly used in electrical equipment
(2) Two-letter symbol Two-letter symbol is composed of one-letter symbol indicating one kind in Table 1-7 and another letter, and the combination form is: single-letter symbol first and another letter after. The two-letter symbol can convey the names of electrical devices, devices, and components in greater detail and more specifically. The other letter in the two-letter symbol usually uses the first letter of the English noun of the device, device, and component, or a common abbreviation, or a conventional custom letter. For example, "G" is the English name of the synchronous generator, and the two-letter symbol of the synchronous generator is "GS". The two-letter symbols commonly used in electrical diagrams are shown in Table 1-7.
Table 1-2 two-letter symbols commonly used in electrical diagrams
Auxiliary text symbols are used to indicate the function, status, and characteristics of electrical equipment, devices, and components, as well as wiring. For example, "ACC" means acceleration, and "BRK" means braking. Auxiliary text symbols can also be placed after a one-letter symbol representing a category to form a two-letter symbol, such as "SP" for a pressure sensor. If the auxiliary text symbol consists of more than two letters, in order to simplify the text symbol, only the first letter is allowed to be combined, such as "MS" for the synchronous motor. Auxiliary text symbols can also be used separately, such as "OFF" for disconnection and "DC" for DC. Auxiliary text symbols generally cannot exceed three letters. The auxiliary text symbols commonly used in electrical diagrams are shown in Table 1-8.
Table 1-3 Auxiliary text symbols commonly used in electrical diagrams
The combination of text symbols is generally: basic symbol + auxiliary symbol + digital serial number.
For example, the first motor has the text symbol M1; the first contactor has the text symbol KM1.
In the electrical diagram, some special-purpose terminals, wires, etc. usually use some special text symbols. For example, the three-phase AC system power supply is represented by "L1, L2, L3", and the three-phase AC system equipment is represented by "U, V, W", respectively.

Battery Holders
Antenk battery holders rely on continuous innovation.
Every year we continue to innovate and create not only new types holders for new kinds of batteries, but also new types of holders for common batteries. Our award-winning designs have been used in all types of projects around the world, and they have been everywhere from under the sea to outer space. No matter what size and shape battery holder is needed, we can provide a solution. Our standard line includes over 250 different battery holders, with enough variations to suit most applications. We also have a long history of delivering custom battery holder solutions, which we optimize to perfectly suit the the needs of our clients.
Specialized Knowledge
Designing the best battery holders requires the best industry knowledge. At Antenk, we have over 15 years of battery holder design experience. We know what works and what doesn't, and we thoroughly test our newest designs to ensure they meet our rigorous quality standards. Understanding batteries and how they vary among brands, the requirements of modern electronics manufacturing practices, and how electronics consumers operate battery holders are all examples of the specific knowledge we apply during our battery holder design process.

Coin Cell Battery Holders
We have created a wide variety of coin cell battery holders for use in all types of devices, and from handheld medical devices to server motherboards we have solutions for any application. The ever increasing types, sizes, and sheer number of devices which use coin cell battery holders have been keeping us busy, and we have a similarly increasing selection of coin cell battery holder designs. After all, the perfect coin cell battery holder for a handheld medical device is going to be vastly different from the one for a server motherboard.
Unique Coin Cell Battery Holders
Antenk has pioneered a large number of new styles of coin cell battery holders to suit the various needs of the electronics industry. Our Verticals are an excellent way to save space on a crowded board, while our Minis can save almost 3 mm in height above the PCB over traditional coin cell battery holders. Gliders are an excellent upgrade over coin cell retainers, offering more reliable connections while also having simple, tool-less battery replacements. Our newest technology is Snap Dragon, which adds a snapping cover to the traditional style of coin cell battery holders for increased reliability.

Coin Cell Retainers
Coin cell retainers are simple metal contacts that both electrically connect coin cells and hold them in place, while taking up minimal additional space on the PCB. They feature nickel-plating, and since most coin cells have nickel shells this helps to prevent galvanic corrosion, an electrochemical process that can damage dissimilar metals that are in electrical contact. Our retainers are always designed with automation in mind, and can be easily picked and placed, with both through hole and surface mount retainers available for most coin cell sizes. Combining the ease of automation with the low cost of Antenk's retainers, it is no wonder they are such a popular product.
