Consumer capacitive touch technology works well for smartphones in clean, dry environments with bare fingers. However, industrial applications present entirely different challenges:
Operation with work gloves
Wet or contaminated surfaces
Temperature extremes
EMI-intensive environments
Traditional solutions often resort to resistive touch, sacrificing the smooth multi-touch experience users expect today.
The SFTO700HX-7388A-CT incorporates industrial-grade PCAP technology that maintains the user experience advantages of capacitive touch while addressing industrial requirements:
The ILI2511 touch IC provides:
Glove touch support without sensitivity adjustment
Wet surface operation with moisture rejection algorithms
Palm rejection to prevent accidental touches
10-point multi-touch capability
G+G (Glass-Glass) structure with chemically strengthened cover glass
6H pencil hardness for scratch resistance
OCA optical bonding for improved optical performance and durability
The USB interface for touch data transmission provides:
Differential signaling for noise immunity
Standardized protocol for easy host integration
Configurable reporting rate to balance responsiveness and power consumption
The touch system maintains performance across the -20°C to +70°C operating range through:
Temperature-compensated algorithms
Stable capacitive sensing across temperature variations
Consistent response time regardless of environmental conditions
Implement touch calibration routines during manufacturing
Utilize gesture recognition for enhanced user interfaces
Consider touch watermarking for safety-critical applications
Allow for proper grounding of the touch controller
Maintain specified cover lens thickness (1.0mm ±0.1mm)
Ensure adequate sealing if environmental protection is required
Saef Technology Limited offers numerous customization options:
Thicker cover glass (up to 6.0mm) for impact resistance
Hydrophobic coatings for improved wet performance
Anti-glare and anti-fingerprint treatments
EMI shielding for sensitive medical or military applications
Industrial-grade projected capacitive touch technology has evolved to meet the rigorous demands of industrial, medical, and outdoor applications. The SFTO700HX-7388A-CT demonstrates that engineers no longer need to choose between advanced touch user experiences and industrial robustness. With support for glove operation, wet conditions, and wide temperature ranges, it brings modern touch interaction to challenging environments. Saef Technology Limited provides the technical expertise and customization capabilities to ensure successful integration into even the most demanding applications.
