High-durability capacitive interfaces engineered for zero failure

Projected Capacitive Technology

Uses an embedded grid of micro-fine sensor electrodes to detect touch through protective cover glass, enabling seamless gesture recognition.

Glove & Wet Operation

Calibrated controller firmware dynamically adjusts sensitivity thresholds to support clinical gloves, heavy work gloves, and reject water droplets.

Display Optical Lamination

OCA/OCR bonding of display to touch sensor eliminates internal reflections, boosting contrast ratio by 300% for extreme outdoor sunlight readability.

Glass-Glass (GG) Structure

Features a rugged tempered cover glass chemically bonded to the sensor glass layer, providing superior durability, scratch resistance, and IK08 impact ratings.

High Noise Immunity

Equipped with industrial EETI/ILITEK touch controllers implementing frequency-hopping and noise filtering to prevent false touches under high electrical interference.

Custom Cover Lens (CG)

Options for custom cover lens printing, custom shapes, cutouts, thickness ranging from 1.1mm to 10mm, and anti-glare (AG) or anti-reflective (AR) surface treatments.

PCAP Stackup Design

Engineered capacitive touch stackup

Projected capacitive touchscreens are the standard for modern, premium user interfaces. Keetronics constructs PCAP layers using top-grade components to ensure flawless HMI responsiveness under heavy duty usage. By eliminating air gaps through optical clear adhesive (OCA) lamination, we protect the displays from temperature shocks, dust, and internal condensation, ensuring long lifecycle longevity.

  • Double-sided ITO sensor film for precise multi-point tracking
  • Chemically strengthened cover glass (Mohs 7+ hardness) up to 10mm
  • Transparent Optical Clear Adhesive (OCA/OCR) bonding
  • Premium anti-glare, anti-reflective, and anti-microbial surface coatings
