GE QPJ-2D101-L2P – Touch Panel Glass Screen for Operator Interfaces

The GE QPJ-2D101-L2P provides a replacement touch-sensitive glass screen for HMI panels. This touch screen measures 230 mm in width and 175 mm in height. It has a thickness of 3 mm, so it fits into existing panel bezels. The unit weighs 0.28 kg, making replacement straightforward and simple.

Touch Technology and Construction

This glass screen uses analog resistive touch technology for reliable operation. The GE QPJ-2D101-L2P consists of two conductive layers separated by air gaps. A flexible top layer registers pressure from finger or stylus contact. The bottom glass layer provides dimensional stability and scratch resistance. The screen transmits 85 percent of the display’s backlight for clarity.

Electrical Specifications and Interface

The touch screen operates on 5V DC supplied by the host HMI device. The GE QPJ-2D101-L2P draws less than 10 mA during normal operation. A 4-wire interface carries X and Y position coordinates to the controller. The screen achieves a resolution of 2048 by 2048 touch points. Response time measures less than 10 milliseconds for fast user interaction.

Mechanical Specifications and Durability

The GE QPJ-2D101-L2P withstands over 1 million actuations at a single point. It requires an actuation force of 0.5 to 1.0 newtons for reliable registration. The glass surface has a hardness rating of 3H for scratch resistance. A 4-pin FPC connector attaches to the host device’s touch controller. The screen includes an EMI shielding layer for noise reduction.

Compatibility and Environmental Tolerance

This touch screen replaces damaged units in specific GE operator panels. The GE QPJ-2D101-L2P operates reliably from 0°C to 50°C ambient temperature. It tolerates humidity levels up to 90 percent without any condensation issues. The screen maintains linearity of ±1.5 percent across the entire active area. A protective shipping film prevents scratches during installation.

Below is a complete summary of its technical specifications.

The GE QPJ-2D101-L2P replaces cracked or unresponsive touch screens in GE HMIs. You do not need any special tools beyond standard screwdrivers. This screen also includes pre-installed adhesive for easy mounting. Consequently, it restores touch functionality without replacing the entire operator panel.
