Siemens 6AV6644-0AB01-2AX0 Overview

The HMI device MP 377 15" touch panel module 6AV6644-0AB01-2AX0 is a SIMATIC HMI component manufactured by Siemens. The design of the 6AV6644-0AB01-2AX0 enables operation under markedly bright light conditions. The MP 377 15" Touch daylight readable offers direct sunlight efficient display and touch technology through the use of transflective display properties fashioned in the panel.  These products are manufactured in Germany and are designed for Automotive, aerospace, power generation, and electronics usage. They come with a 2-year warranty from MRO Electric. We also carry HMIs from other manufacturers such as FANUC and Yaskawa.

Features of the Siemens 6AV6644-0AB01-2AX0

The 6AV6644-0AB01-2AX0 MP 377 15" Touch daylight readable panel possesses an aluminum-coated front frame coved with impact-resistant paint. The glass on the panel enjoys high resistance against harsh cleaning agents and chemicals and it rates a 7 on the Mohs hardness scale. The panel certifications are geared toward a potentially explosive environment and for control stations.

The display is suitable for daylight applications. The HMI panel unit employs LED backlighting which has high contrast (up to 1000: 1), high brightness (up to 800 cd/m²), and energy-saving qualities. The panel retains good readability when used in high sunlight as well as dark. This is accomplished through transflective technology. Transflective technology uses both reflective and transmissive properties to offer good readability in both environments. The viewing angle is up to 160 degrees.

The SIMATIC 6AV6644-0AB01-2AX0 retains a sturdy touch surface for occupying rough environmental conditions. Rough environment considerations implemented in the design of the panel include Mohs 7 surface hard glass, exceptional optical properties, and ease of operation when wearing thin gloves. Recalibration is not required with this no drift unit.  The module is made for use in all kinds of environments including dusty, humid, rain, snow, and ice.

What is the benefit of using the Siemens 6AV6644-0AB01-2AX0 SIMATIC HMI component? The distinguishing feature is the ability to dim the backlighting of the display in two ways. The backlighting can be dimmed internally on the panel itself and the backlighting can be dimmed on this module externally; this is done through a central process value (i.e. through a potentiometer by way of the PLC). This feature is valuable in situations where outdoor use is often in direct sunlight. Situations such as in control cabins on drilling rigs, and onboard ships where the control station is often in direct sunlight. Note that outdoor use is only permissible when the HMI device is installed in a recommended control cabinet. The control cabinet assists in controlling the ambient temperature, heating, or cooling the cabinet during operation. A reliable technician is suggested for cabinet design and a TEK (Temperature Extension Kit) panel option may be necessary.


Mounting the Siemens HMI device MP 377 15" touch panel module 6AV6644-0AB01-2AX0

The SIMATIC HMI 6AV6644-0AB01-2AX0 can be installed vertically as well as at an angle. Control cabinet mounting for the device is necessary as the device is not manufactured with a fan.
