Since its establishment in 1995, Shenzhen Keyu Co., Ltd has been dedicated to the research and production of metal keyboards, encrypted password keyboards, and trackball integrated devices. It has its own 4,000-square-meter standardized production base, equipped with AMADA CNC punching machines, precision etching, and electroplating blackening production lines. The products have passed multiple authoritative certifications such as CE, FCC, RoHS, IP65 waterproof and dustproof, explosion-proof, and PCI financial security. They are exported to global markets including Europe, Southeast Asia, and the Middle East. It is a long-term supplier for self-service terminals, financial equipment, industrial control cabinets, and other leading equipment in the industry. The newly launched KY-PC-NT3-LED and KY-PC-F4-LED-BL backlight series models have completed comprehensive technical upgrades to address the industry's pain points such as the lack of light on traditional metal keyboards, difficulties in night operation, and poor environmental adaptability.
1. High-quality stainless steel substrate, ensuring both explosion-proof and anti-corrosion properties as well as smooth backlight and light transmission.
The entire backlit keyboard panel and keys are uniformly made of SUS304 brushed stainless steel through one-piece stamping. A 3mm thick aluminum alloy base plate is added for reinforcement. The entire machine reaches the IK08 explosion-proof level. It is resistant to impact, scratch, acid and alkali corrosion, and can be used stably for a long time in humid, dusty, and oily complex working conditions.
In terms of technology, it breaks through the limitations of traditional etching. The key characters adopt a dual process of hollow light transmission and laser etching: the characters of the plain color stainless steel model have soft light transmission; the key surface of the electrostatic blackening model is matte pure black, with uniform character gaps that emit LED cold light, providing a visually superior effect without reflecting light, completely solving the industry problem of unclear key readings in dim light environments. The keyboard as a whole has IP65 sealing protection. It is pressure-free to be rinsed with clean water or wiped with disinfectant solution, and is suitable for high-cleaning demand scenarios such as medical, food processing, and outdoor self-service equipment.
II. Intelligent and controllable LED backlight system, with multiple specifications for customization to fit various scenarios
The Kowei backlit metal keyboard is equipped with a low-power LED backlight module, with a working current of less than 100mA and a DC5V standard wide-voltage power supply. It does not cause overheating even when turned on for a long time, and the backlight brightness can be adjusted as needed and supports switch control, eliminating night-time light pollution.
The product line covers full-size specifications:

The product line covers full-size specifications:
- Full-function 103-key standard industrial control model: Integrates a complete PC key layout, offers the option of a built-in touchpad or metal trackball, providing a one-stop alternative to a keyboard and mouse combination;
- 66-key compact embedded model: Suitable for installation in narrow spaces of cabinets and CNC operation consoles;
- Compact digital encrypted backlit keyboard: Supports DES, 3DES, SM2/SM3/SM4 national encryption hardware encryption, suitable for financial security scenarios of ATMs and government payment terminals.
Backlight colors support customization in multiple colors (blue, white, green), and various language key layouts, custom function shortcut keys, and combination keys can all be developed as needed, perfectly meeting the customization requirements for overseas export equipment.
III. Maintains industrial-grade performance with an extremely long service life of over a million cycles.
The core electrical and structural parameters are all designed in accordance with military industrial control standards: the standard travel of the buttons is 1.5mm, the contact spring force is 2N ± 0.1N, the single-key impact life is ≥ 2 million times, and there is no jamming or disconnection during continuous high-frequency operation for many years; the communication interface is compatible with three mainstream industrial interfaces: USB, RS232, and PS/2, and it perfectly adapts to all series of operating systems including Windows, Linux, and Android.
The temperature adaptation range covers -20℃ to 70℃, and the equipment can operate stably in both low-temperature outdoor and high-temperature workshop environments; the standardized bottom plate screw-fixed installation structure from bottom to top, with pre-installed positioning holes, enables efficient and convenient assembly of the entire equipment, significantly reducing the assembly time for customers at the terminal.
4. Full-scale application across the industry, with batch production of terminal equipment for both domestic and international markets
The Kowei backlit metal keyboard, with its durability and dark-light operation advantages, has been adopted in core devices across multiple fields:
