Mix and match from STRONGARM’s ever increasing array of mountings, displays, touchscreens, keyboards, pointers and options below to create your optimal system.

Your system will arrive pre-assembled, tested and ready-to-install.

You’ll also benefit from the advantages of split architecture, in which the PC is separated from the display. Options include an internal micro PC, a desktop PC in a protective local enclosure, or a remote PC up to 3000' away connected by a simple CAT 5 cable.

Also available in NEMA 4/12 version.

Resistive Touchscreen
(for 90% of all touchscreen applications)
The resistive touchscreen uses a glass panel overlay with a uniform resistive coating. A polyester coversheet is tightly suspended over the top of the glass, separated by small, transparent insulating dots. The coversheet has a hard durable coating on the outer side and a conductive coating on the inner side. When the screen is touched, the conductive coating makes electrical contact with the coating on the glass. The voltages produced are the analog representation of the position touched. The controller digitizes these voltages and transmits them to the computer for processing.

Surface Acoustic Wave Touchscreen
(safest touchscreen for hazardous area applications)
The Surface Acoustic Wave Touchscreen has a glass overlay with a grid of transmitting and receiving piezoelectric transducers. The touchscreen controller sends a 5 mHz electrical signal to the transmitting transducer,which converts the signal into ultrasonic waves within the glass. When the screen is touched, a portion of the wave traveling across it is absorbed, thus changing the received signal. The signal is then compared to a stored reference signal, the change recognized, and a coordinate calculated. The process happens independently for both the X and Y axes. By measuring the amount of the signal that is absorbed, a Z-axis is determined.

Infrared Touchscreen
(for applications where touchscreen is exposed to extreme abuse)
The Infrared Touchscreen relies on the interruption of an IR light grid in front of the display screen. Integrated into the display bezel is an opto-matrix frame that contains a row of IR-light emitting diodes (LEDs) and photo transistors, each mounted on two opposite sides to create a grid of invisible infrared light.The opto-matrix frame is isolated from the outside environment by an IR transparent barrier. The IR controller sequentially pulses the LEDs to create a grid of IR light beams. When a stylus, such as a finger, enters the grid, it obstructs the beams. One or more of the phototransistors detects the absence of light and transmits a signal that is the X and Y coordinates. Because the infrared scanning is done in front of the display, a bulletproof, 3/8" thick polycarbonate window is installed between the IR grid and the display itself. This window provides a level of environmental protection for the electronics that is unique to the infrared touchscreen technology.
