Siemens 6FC5303-0AA00-2AA0 Overview

The Siemens SINUMERIK HT 2 (Handheld Terminal 2) 6FC53030AA002AA is a rugged and easy-to-use handheld terminal designed for manual operation of machine tools. Its ergonomic design and low weight make it ideal for extended periods of use, particularly when mobile operation is necessary during setup. 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 Accessories from other manufacturers such as FANUC and Yaskawa.

The HT 2 can be connected to any system location via a PN Basic terminal box or a PN Plus terminal box. When used with the PN Plus terminal box, it can be easily withdrawn and inserted during operation without initiating an emergency stop.

For mounting in the control cabinet, the HT 2 is connected with a connection module PN Basic. It is suitable for both right-handed and left-handed personnel and features two enabling buttons, as well as a magnetic handwheel for intuitive axis feed motion. All of the HT 2 keys can be freely configured and labeled.

To mount the HT 2, a retaining magnet or appropriate bracket can be used, both of which are available as accessories.


The Siemens 6FC53030AA002AA0 unit contains a PCB with CPU and memory, as well as an Ethernet controller. The device front features a black and white LC display with a resolution of 168 x 72 pixels, capable of displaying four lines of 16 characters. There is also a 20-key membrane keyboard, with 16 machine control keys and four keys in the upper row that can be assigned as softkeys or system keys. The device also includes a 2-channel emergency stop button, a 19-position rotary override switch, and a magnetic handwheel. On the device's rear side, there is a recess for the bracket or retaining magnet, as well as a cable duct for the connecting cable to the PN (Basic/Plus) terminal box or the PN Basic connection module. The right-hand side of the device features a key-operated switch with two keys and a 2-channel, 3-stage enabling button, while the left-hand side also includes a 2-channel, 3-stage enabling button.


The display of the 6FC53030AA002AA0 Handheld Terminal HT 2 has an LCD display in black and white. It has a resolution of 168 x 72 pixels, which enables a display of up to four lines of 16 characters each when using a basic font with a height of 16 pixels. The display is a key feature of the handheld terminal, allowing users to view and interact with the device's interface. With its high resolution and clear display, users can easily read and understand the information presented on the screen. This makes the 6FC53030AA002AA0 Handheld Terminal HT 2 an efficient and user-friendly device for various industrial applications.

The HT 2 has 20 keys, each with its own LED. Out of these keys:

  • The upper row of keys, which consists of 4 keys, can be used as both softkeys and system keys.
  • The remaining 16 keys are dedicated to controlling the machine.

When the HT 2 is first supplied from the factory, it comes with five horizontal slide-in labels.
