Key Automation is a dominant matrix keyboard manufacturers and suppliers in India. Our matrix keyboards are made with new advanced technological aspects and used in various applications, such as consumer goods and industrial processes, due to their higher durability.

Usually, the keyboard matrix in a membrane switch is connected under the conductive layer of the keyboard, and switches are separated by a spacer. When the key is pressed, it completes the circuit and gives accurate output. Let’s delve into the multiple types of our matrix keyboard, applications, features and various benefits.

All keys are connected in a row and column form and arranged in a grid pattern. When a specific key is pressed, it scans the overall corresponding row and column and completes the circuit. This method helps reduce the number of input/output (I/O) pins required and can be applied where there is a limited number of I/O availability.

Being one of the best matrix keyboard manufacturers in India, we are offering numerous types of keyboards that are used in various applications. Here we have listed down some types:

• 4/3 matrix keyboard: It consists of 4 rows and 3 columns and forms a grid of 12 keys. Due to their compact design, these are usually used where a limited number of keys is required, such as in calculators, simple user interference and basic control systems. The 4 rows are connected to the input, and 3 columns are connected to the output level in the microcontroller and scan the overall process when the key is pressed. A 3.3V to 5V voltage is required for operating.
• 4×4 Matrix 16 Keypad Keyboard: These keypads have the structure of 4 rows and 4 columns and form a grid of 16 keys. These are largely used in microcontroller processes, security systems and handled devices for fast processing and more input options. It is similar to 4x3 matrixes, but only one additional column has been added for more keys. A 3.3V to 5V voltage is required for operating.
• Standard Matrix Keyboards: These keyboards have a large interface and configuration, such as 8x8, depending upon the applications. The multiple membranes are attached for more efficient workflow, and an advanced mechanism microcontroller is attached for accurate output. These keyboards are used for multiple purposes, such as computer keyboards, gaming consoles and industrial control panels.
• Alphanumeric Matrix Keyboard: This keyboard has a grid of keys that contains alphabets, numbers and also some symbol keys such as! @, #, $, etc. These are specially used where multiple functions or tasks are required, such as industrial control panels, medical devices, kiosks and point-of-sale (POS) systems. It is more user-friendly for operating due to all required keys being present on the panel.

As leading matrix keyboard manufacturers in India, we have added various new technological configurations to our matrix keyboard, such as:

• Scalability and Expansion: This is the primary feature of our matrix keyboard due to more flexibility for connecting multiple applications such as industrial control panels and complex user expansion. The additional rows and columns can be easily added without any complex wiring and are also able to create large arrays.
• Advanced Programmability: We have added advanced programming to all types of matrix keyboards, which helps for quick responses, even the micro commands. This feature allows for more customization in multiple applications, such as industrial machines and special control systems.
• Multi-Layer PCB Integration: Our all-matrix keyboards can also be compatible with PCBs (Printed Circuit Boards) for more flexibility and more complex circuit designs without increasing the physical size of the keyboard. The PCB design helps give more accurate feedback to matrix keyboards due to its advanced algorithms and is used in multiple functionalities such as backlighting, touch sensors and embedded microcontrollers.
• Touch Sensitive Options: Our matrix keyboards also come in touch or capacitive keyboards for reducing any physical intervention and helping to speed up the operations. These keyboards are used where more durability is required, such as in outer conditions, medical equipment, cleanroom environments and commercial sectors.

Due to its advanced technological features and quick response without any failure, our matrix keyboards are used in numerous applications, such as:

• Telecommunications: These are highly used in telecommunication systems due to their customizability and are applied in telephone keypads; switch pads and communications control systems.
• Military and Defense: Out matrix keypads are also used in rugged conditions such as military operations and employed in conditions such as communication devices, vehicle control systems and secure control systems.
• Smart Home and IoT Devices: Due to the rise in technological evolution, the integration of IoT is increasing. Our matrix keyboard contributes more to improving performance and is used in smart home control panels, security systems, and home automation interfaces.
• Banking and Financial System: For security and efficient workflow in the financial systems, our keyboards are used in certain applications such as ATMs, secure transaction devices and customer service terminals. These are more durable and give a long-lasting performance.

Being one of the best matrix keyboard manufacturers and suppliers in India, we, Key Automation, are providing new technological matrix keyboards that are essential for improving productivity and performance in every application. The advanced programming systems and algorithms help speed up the performance and give a quick response. These are also safely used in outer conditions. Contact us today for more information!
