LAUER LXT-K10m / Beijer EXTER-K10m Operator Interface – Keypad HMI Panel
The LAUER LXT-K10m, also known as the Beijer Electronics EXTER-K10m, is a compact and reliable operator interface panel designed for industrial control and monitoring applications. This keypad-operated human-machine interface device provides operators with an efficient means of interacting with programmable logic controllers and industrial control systems.
Product Overview
The EXTER-K10m is part of Beijer Electronics' EXTER series of operator panels, manufactured in collaboration with Elektronik-Systeme Lauer GmbH & Co. KG[reference:45]. This operator interface is designed for stationary installation on a plane surface in industrial environments, providing a durable and cost-effective solution for machine-level control and visualization[reference:46].
The device features a keypad interface complemented by a monochrome FSTN display, offering a balance of functionality and simplicity for industrial applications where full graphical touchscreen capability is not required[reference:47]. The EXTER-K10m is particularly well suited for text-based operator interfaces, alarm management, recipe handling, and machine status monitoring.
Display and User Interface
The LAUER LXT-K10m / Beijer EXTER-K10m features a monochrome FSTN display with a resolution of 160 x 32 pixels[reference:48]. This display resolution enables the use of text, numeric values, and simple graphics for operator communication. The FSTN technology provides good contrast and viewing characteristics suitable for industrial environments[reference:49].
The operator interface is operated via a membrane keypad, providing tactile feedback for operator input. The keypad design includes function keys and navigation controls, enabling operators to navigate menus, enter data, and control machine functions efficiently. The device supports functions including text display, text control, dynamic display, time channels, alarm management, and recipe handling[reference:50].
Technical Specifications
The LAUER LXT-K10m / Beijer EXTER-K10m operates on a 24 V DC power supply[reference:51]. The front panel dimensions are 155 mm in width, 114 mm in height, and 6 mm in depth[reference:52]. The total device depth including mounting requirements is 52.4 mm[reference:53]. The cutout dimensions for panel mounting are 121 mm by 80 mm[reference:54]. The device weighs approximately 0.45 kg[reference:55].

Communication and Connectivity
The LAUER LXT-K10m / Beijer EXTER-K10m provides serial communication capabilities through RS232 and RS422/485 interfaces[reference:66]. The device features one 9-pin D-sub serial port for connection to PLCs and controllers[reference:67]. The operator panel has galvanic isolation against the 24 V DC power feed, protecting the device and connected equipment from ground loop issues[reference:68].
It should be noted that the EXTER-K10m does not support Compact Flash cards or TCP/IP connection functionality[reference:69]. The device is designed for serial communication only, making it suitable for applications where simple, reliable serial connectivity is sufficient.
Installation and Mounting
The LAUER LXT-K10m / Beijer EXTER-K10m is designed for panel mounting on a flat surface[reference:70]. When installing the operator panel, the enclosure provides a degree of protection of at least IP20, but when properly installed in a panel, the front face achieves IP66 protection rating[reference:71]. This makes the device suitable for applications where exposure to dust, moisture, and washdown is possible[reference:72].
Installation guidelines include separating high voltage, signal, and supply cables, ensuring correct voltage and polarity of the power source, and using appropriate peripheral equipment for the application and location[reference:73]. The operator panel is designed for stationary installation on a plane surface where specific conditions are fulfilled[reference:74].
Applications
The LAUER LXT-K10m / Beijer EXTER-K10m is suitable for a range of industrial applications requiring text-based operator interface with keypad input:
Machine control and monitoring
Process visualization and control
Alarm management and notification
Recipe handling and selection
Production data entry and display
Retrofit of legacy control systems
Configuration and Programming
The LAUER LXT-K10m / Beijer EXTER-K10m is configured using Beijer Electronics' Information Designer software, the configuration tool used to create applications for operator panels in the EXTER series[reference:75][reference:76]. This software enables engineers to design the operator interface, define communication parameters, and configure system behavior. The development environment supports the creation of text displays, alarm management systems, recipe handling, and other operator interface functions[reference:77].
Safety and Compliance
The LAUER LXT-K10m / Beijer EXTER-K10m is suitable for use in Class I, Division 2, Groups A, B, C, and D hazardous locations, as well as non-hazardous locations[reference:78]. The device complies with relevant industrial safety standards and is designed for use in industrial environments. The operator panel or parts thereof should be recycled according to local regulations, with particular attention to components containing substances that may be hazardous to health and the environment, including the lithium battery, electrolytic capacitor, and display[reference:79].
The LAUER LXT-K10m / Beijer EXTER-K10m operator interface provides a reliable and cost-effective solution for industrial HMI applications, combining robust construction with straightforward operator interaction in a compact panel-mount design.
