FPM-3170G User Manual 16
Mechanical
Linearization: Factory linearization values are stored in the touch-
screen NOVRAM, attached controller or 2D bar-code
Touch Contact Requirement: 3 ms for finger input.
Glass Thickness: 0.125" (±0.01") / 3.18mm (±.25mm) typical. (Glass
only, not including tape, wires and solder if used)
Surface Scratch Hardness: Can not be scratched using any stylus
with Mohs’ rating of less than 6.5. Exceeds severe abrasion test per
MIL-C-675C. Withstands 10,500 grams of force per Balance Beam
Scrape Adhesion Mar Tester. MicroScratch tester with 10 micron
radius tungsten carbide indenter takes a force of 1.8 Newtons.
NEMA Rating: NEMA sealable.
Gasketing: Complete water-resistant seal obtainable with polyethyl-
ene gasket.
Cleaning: Water, isopropyl alcohol, and similar non-abrasive cleaners.
Reliability
Endurance Test: A capacitive sensor with Industrial etch has been
tested in a laboratory environment to withstand over 225 million
mechancial touches without noticable degradation to the surface.
Surface Obstructions: Touch screen’s operation unaffected by sur-
face obstructions such as dirt, dust, grease, smoke, peanut butter, etc.
Chemical Resistance: Capacitive sensor is highly resistant to corro-
sives, in accordance with ASTM-D-1308-87 (1993) and ASTMD-F-
1598-95.
Liquid Resistance: Liquids on screen do not impede touchscreen per-
formance.
Liquid Repellence: Contact angle of 94° and greater measured using
Sessile Drop Contact Angle Method. This renders the screen
extremely water repellent.
Operating Temperature Range: -15 to 70°C for touch screen.
Storage Temperature: Always store the touch screen sensor in its
original shipping container between -50 and 85° C (MIL-STD-
810E). Never store touch sensors where condensation may form.
