Rugged Analog Touch HMIs

Resistive Touch Displays

Introducing our line of high-reliability 4-wire and 5-wire resistive touchscreen displays, optimized for extreme environments. Using pressure-activated touch technology, these screens operate seamlessly with bare fingers, heavy industrial work gloves, or any mechanical stylus. Featuring optional Glass-Film-Glass (GFG) Armor construction for superior scratch and chemical protection, ensuring fail-proof operation near machinery.

Resistive Touch Engineering

Pressure-based touch panels built for heavy duty industrial consoles

Pressure-Based Activation

Acts on physical pressure. Operates with heavy industrial gloves, thick leather mitts, a generic plastic stylus, pens, or fingernails.

Glass-Film-Glass (GFG)

Laminates a thin, flexible glass sheet over the polyester surface, protecting the display from scratches, cuts, and vandalism while retaining touch sensibility.

Superior EMI Noise Immunity

Analog resistive panels utilize simple electrical resistance values, making them entirely immune to high electromagnetic noise and RF interference.

Liquid & Dust Rejection

Unaffected by pooled water, mud, dirt, heavy grease, chemicals, or machine oil spills on the sensor surface, ensuring reliable operation under washdown.

4-Wire & 5-Wire Selection

Choose 4-wire for budget-friendly projects or 5-wire design for high duty-cycle setups where coordinate calculation remains active if surface scratches occur.

Display Lamination

Supports optical bonding (OCA/OCR) to the underlying LCD module, reducing light reflections, preventing condensation, and maximizing shock resistance.

Glass-Film-Glass heavy-duty stackup

Standard resistive screens suffer from vulnerable outer PET layers that scratch easily. Keetronics offers Glass-Film-Glass (GFG) lamination, replacing the top plastic surface with a micro-thin, flexible glass sheet. This provides a hard Mohs 5+ barrier that resists scratches, chemicals, and hot sparks, while retaining the glove-friendly pressure-sensitive touch activation of classic resistive panels.

  • Micro-thin top glass layer for scratch and spark immunity
  • Unaffected by hydrocarbons, organic solvents, acids, and cleaning chemicals
  • 5-Wire coordinate structure: long life-cycle operations
  • Full gasket sealing matching IP67 / NEMA 4 front requirements
