Which is your touch?
The capacitive touchscreen is covered with a thin layer of metal oxide, allowing the charge applied at the four corners of the panel to propagate evenly. When a finger or conductor material touches the screen, it changes the surface capacitance, which is detected by a grid of film condensers beneath the glass. This type of screen is perfect for those who appreciate touch sensitivity, as you only need to bring your finger up to the screen to interact with the system, without applying pressure.
The capacitive touchscreen also offers excellent visibility and transparency thanks to the use of glass, compared to resistive screens which use a double protective layer. However, capacitive touchscreens are less resistant to electromagnetic disturbance and less suitable for particularly dirty environments or those requiring non-tactile gloves. Available in 7, 10 and 18-inch sizes, our capacitive touchscreens can be supplied with IP65 protection.
On the other hand, a resistive HMI uses two layers of conductive material separated by an insulating layer. When the screen is pressed, the two layers come into contact and create an electrical signal sent to the device processor. This type of screen detects touch with great precision, even when using a stylus or gloved finger. It is particularly durable and resistant to dust, moisture and other environmental factors, making it ideal for challenging industrial settings. It works well with work gloves or protective coverings, essential for operator safety.
Why choose a resistive HMI? It’s strong, versatile and affordably priced! Available in 7, 10 and 15-inch sizes, which can be supplied as IP65 compliant, with resistive touchscreens and membrane keyboards surrounding the display for even simpler and more intuitive use. In addition to the standard 28, 56 or 80 key versions with emergency button (typical of ISO machines), the front panel can be customised to your configuration and logo.
