HDSP-K211

The HDSP-K211 is a single-digit, light-emitting diode (LED) display module that has become a popular choice for many industrial, consumer and commercial device applications. LED displays are often used for applications where reliability and performance are essential, such as data displays for access control systems, test instrumentation and medical equipment. The HDSP-K211 can also be used for embedded applications, such as programmable logic controllers (PLCs) and process controllers.

The HDSP-K211 is a seven-segment, common cathode (α) display. It offers an easy-to-handle package that measures just 33.2mm x 8.5mm x 6mm and a bright red segmented display that is easily visible in any environment. The module can be used with a wide range of digital input voltages of 5.0V to 20.0V, and it features current-limiting diodes for protection against overvoltage. The module has also been designed with a narrow viewing angle, giving it superior brightness uniformity and excellent readability in even the toughest environments.

The HDSP-K211 operates with a single power supply, using a direct connection to the LED segments. It uses an active low input logic, which means that it’s possible to drive the LED display directly from a microcontroller without the need for an external driver. This reduces system cost and complexity, allowing designers to produce cost-effective, compact displays with variable brightness levels.

The quality of the HDSP-K211 display is outstanding, both in terms of brightness uniformity and readability. An integrated filter reduces any optical noise, and there is no measurable flicker within the human range of vision. The module is also highly reliable, with a working life of more than 100,000 hours, and it has a low power consumption of just 200mW.

HDSP-K211 application fields include, but are not limited to, industrial panels and hand-held machines, automotive meters, test & measurement instruments, medical devices, in-store displays, digital signage displays, and many others. Thanks to its features, such as its brightness uniformity, high readability and lightweight package, the HDSP-K211 is an ideal display solution for most applications that require a single-digit, alpha-numeric display.
