The stylus pens produced by our company mainly include the following types:
Passive Electromagnetic Stylus Pen
The passive electromagnetic stylus pen is also used in digital drawing and graphic design applications. They offer better precision and control than using fingers or mouse, making it easier to draw complex shapes and lines.
Active Electromagnetic Stylus Pen
An active electromagnetic pen (also known as an active stylus) is a pen that interacts with a digital device through an electromagnetic field. Unlike the traditional stylus, which relies entirely on capacitive touch, the active electromagnetic pen uses EMG to communicate with equipment.
Advantages of Stylus Pen




They’re great for handwritten notes
Whether you’re a college student, a busy professional, or a creative on-the-go, having the ability to jot down notes that feel more fluid than mere text will make a world of difference in your work. Whether your device of choice is a pocket-sized smartphone or a larger tablet or convertible laptop, a stylus is a sleek alternative to your fingertip that offers precise linework and legible lettering.
They’re easy to use
Though everyone’s fingers are different sizes, it’s a simple fact that fingertips are generally bulbous, clunky, and oftentimes too cumbersome to produce the meticulous precision you desire. This is where styluses reign supreme. One of the most alluring aspects of a stylus is that they are incredibly easy to use. Someone who has never seen or touched a stylus before could easily pick one up and master the basic functionality.
They’re weather resistant
Operating a capacitive touch screen in cold temperatures can be an aggravating experience. When the environment around you is cold and your fingertips are just as frigid, your touch screen device will have a hard time registering contact. This often results in a number of frustrated jabs at your screen - leaving your fingers even colder and your patience worn thin.
They offer more precise contact registers
No matter what size screen you’re working with, creating thin, precise lines can be next to impossible when the width of your fingertip covers your linework. The smaller the device, the more real estate your finger will take up as it drags along. A stylus’ smaller tip can provide increased accuracy and deliver more pristine linework than that of your fingertip.
They’re more sanitary than bare fingers
If you’re at all bothered by a screen full of greasy smudges or gunk-filled crevices, you’re not alone. Sparkling touch screens quickly transform into fingerprint-covered messes - effectively compromising the pristine status of your device. Styluses keep your screen cleaner and more smudge free than your fingertips ever could.

Touch Principle |
Controlled by pressure sensing and sense the resistance change of the touch position. |
A Conductor for simulating a finger. The screen senses the capacitance change and recognizes the position. |
When touching on the screen, the built-in circuit of the pen emits a signal to the touch screen to make the screen senses the touch position. |

Notes on Using the Stylus Pen
The Tail cap contains a magnet. Do not bring an object easily affected by magnetic interference (such as a credit card) close to the pen. Doing so may result in loss of recorded data.
If you use an app that uses the digital compass, keep the pen away from your computer to prevent the built-in magnet of the Tail cap from affecting the magnetometer on the computer.
You can use the pen with your hand resting on the screen. If you move the pen towards the touch screen, you cannot control the touch screen with fingers.
Depending on the screen, you may not be able to use the pen to scroll the screen.
This pen does not have a power supply switch. Insert the required battery in the pen to operate.
If the pen does not function correctly, replace the battery.
The writing feeling of the supplied nib differs from the feeling of the attached nib. Replace the nib with the supplied one to change the feeling.
To prevent them from being swallowed, keep small parts (such as the nib, Tail cap, pen hook, and battery) out of reach of children.

Packaging and Shipping
|
Packaging |
1. Honeycomb cartons are used outside, and pearl cotton is used inside the honeycomb cartons. 2. The goods exported to foreign countries will be packed in additional wooden boxes outside the honeycomb carton due to the impact of the humid environment of sea transportation or the impact of air transportation. 3. The packaging method can be customized according to customer requirements. |
