Data Sheet (PDF 176 KB)


  • Input Method: Finger input
  • Accuracy*: Reported touch coordinates are within 1.0% of true position (based on the diagonal dimension of the screen) within the precision area when linearized and used with MicroTouch™ EX II Series Touch Controllers
  • Resolution: Touch screen resolution defaults to settings in the electronics and software, generally 1024 x 1024, but capable of 16K x16K when used with EX II electronics
  • Linearization: Factory linearization values are stored in the attached controller, represented in a 2D bar code, or in the touch screen NOVRAM when present


  • Light Transmission**: 91.5% light transmission (±1.5%)
  • Surface Finish: ClearTek II hard coat with optimal anti-glare properties. Scratch resistant top coat provides smooth, easy glide touch surface
  • Fast, accurate and reliable touch response
  • 3M-proprietary hard coat provides premium surface wear resistance for heavy-use applications
  • Operation is unaffected by on-screen contaminants
  • Resilient top coat creates a scratch-resistant, easy-glide surface
  • Excellent light transmission of 91.5% provides vibrant optical characteristics with optimal anti-glare properties
  • Solder less, low-profile design and robust tail simplifies integrations and improves sealability.


  • Minimum Contact Requirement: 5.4 ms for finger input with EX II series controller
  • Glass Thickness: 3.18mm (±0.25mm) typical. (Glass only, not including flexible tail connection; reference touch screen drawing for details.)
  • Display Size Supported: 6.4" to 32" diagonal (4.3, 16:9, 16:10)
  • Surface Scratch Hardness: A Mohs pick with a hardness rating of 7 or higher is required to induce a scratch which will cause a functional failure. Functionality unaffected by severe abrasion per MIL-C-675-C, exceeding number of specified cycles. Functionality unaffected by 10,500 grams of force per Balance Beam Scrape Adhesion Mar Tester with loop stylus
  • NEMA Rating: NEMA sealable
  • Gasketing: Complete water-resistant seal obtainable with polyethylene gasket. Please consult ClearTek™ II integration guide for further details
  • Mounting: Please consult MicroTouch™ ClearTek™ II Integration Guide for specific mounting instructions.
  • Cleaning: Water, isopropyl alcohol, or similar non-abrasive cleaners


  • Surface Obstructions: Touch screens operation withstands surface contaminants such as, dirt, dust and grease
  • Chemical Resistance: ClearTek™ II is highly resistant to a variety of solvents, acids, and household chemicals in accordance with ASTM-D-1308-02e1 and ASTM-F-1598-95 (reapproved 2002)
  • Liquid Resistance: Liquids on screen do not impede touch screen performance
  • Operating Temperature: -40° C to 70° C for the touch screen
  • Storage Temperature: Always store the touch screen in its original shipping container between -50°C and 85°C (up to 90% RH from 0° C to + 35° C). Never store touch screens in an environment where condensation may form
  • Humidity: Up to 90% RH from 0° C to +35° C, non-condensing
