ST-ExHMI Series Industrial Explosion-Proof HMI

The ST-ExHMI Series industrial explosion-proof touchscreen innovatively employs capacitive touch sensing technology to enable touch operation on the explosion-proof display. It also achieves a seamless, flush integration between the viewing window and the explosion-proof enclosure housing.

Certified with Flameproof Explosion-proof Certification, this product is specifically designed for human-machine interface (HMI) applications in hazardous explosive areas.

What is a Capacitive Explosion-Proof Touchscreen?​

  • Innovative use of capacitive touch sensing technology to achieve explosion-proof display touch operation;
  • Innovation to achieve a flat appearance of ​Windows and explosion-proof housing;
  • With ​a variety of sizes, touch screen brands (Siemens, Kunlun, etc.) to choose from, to meet the different needs of customers.
  • The product has obtained flameproof explosion-proof certification and is suitable for human-machine interaction interface in explosive dangerous places;

Why Choose Capacitive Touchscreens?​

  • Capacitive touch screen senses light and fast touch. High sensitivity, fast response speed. 
  • Support multi-touch, operation more intuitive, more interesting. Bright colors and high definition.
  • High durability, longer actual use time: compared with resistive touch screen, capacitive touch screen has better performance in dust, water, wear and other aspects.
  • Scratch-resistant, not afraid of dust, water and dirt, make the capacitive touch screen have a longer service life.
