7 Segment LED Display uxcell Common Cathode Red 0.8″ Tube 5pcs

Description

Product Overview

The uxcell 7 segment LED display is engineered as a common‑cathode red digital tube, offering a clear and bright numeric readout in a compact form factor. Measuring 0.8 inch (approximately 20 mm) in height with a panel size of 28 × 20 × 9 mm, the display fits easily into tight spaces while delivering high visibility. Constructed from durable plastic and metal components, the unit provides a robust housing that resists impact and environmental stress. Each segment is designed to operate at a forward voltage of 2 V and a continuous forward current of 20 mA, resulting in a modest power consumption of just 36 mW per tube. The luminous intensity of 11 mcd ensures that the red digits are easily readable under a variety of lighting conditions, from low‑light environments to bright industrial settings.

Usage

This display is versatile and finds application across a broad range of industries and hobbyist projects. In home appliances, it can be used for temperature readouts, timer displays, and status indicators on washing machines, ovens, and coffee makers. Instrument panels in laboratory equipment benefit from its precise digit representation, allowing technicians to monitor voltage, current, or frequency values with confidence. Automotive accessories such as dashboard gauges, fuel level indicators, and diagnostic tools also leverage the display’s reliability and low voltage requirements. For DIY enthusiasts and makers, the tube is an excellent choice for educational kits, Arduino or Raspberry Pi projects, and custom electronic prototypes where a clear numeric output is essential.

FAQ

What voltage should I use to drive this display?

The display is designed to operate at a forward voltage of 2 V per segment. For optimal performance, use a constant‑current driver that supplies 20 mA to each segment, avoiding constant‑voltage sources that can cause uneven brightness.

Can I connect multiple displays together?

Yes, multiple common‑cathode displays can be connected in parallel on the cathode side while each segment is driven individually. Ensure the driver can handle the combined current load, typically 20 mA per active segment.

Is this display suitable for outdoor use?

The display’s plastic housing provides some protection against dust and moisture, but it is not rated for direct exposure to rain or extreme weather. For outdoor applications, consider adding a protective enclosure with appropriate sealing.

What is the recommended method for mounting the display?

The display can be mounted using standard PCB solder pads or through-hole sockets. Align the pins with the PCB layout to ensure a secure mechanical and electrical connection, and avoid excessive heat during soldering to protect the LED elements.

Do you provide any design resources or driver circuits?

Yes, uxcell offers reference schematics and example code for popular microcontroller platforms such as Arduino and Raspberry Pi. These resources help you quickly set up multiplexed driving and integrate the display into your projects.
