Key Features
- High-efficiency red LED display with 3.71 mm character height provides clear alphanumeric readout visible from over 1 meter in typical indoor industrial environments
- TTL-compatible serial interface operating at 5V logic levels enables direct connection to 5V microcontrollers and PLCs without external level-shifting circuits
- Dual-in-line (DIP) package with standard 0.1-inch pin spacing simplifies through-hole PCB integration and allows easy prototyping on breadboards and prototype boards
Applications
The HCMS-2902 is well-suited for industrial equipment front panels, test and measurement instrument displays, and factory automation HMI units where bright red alphanumeric characters must be visible under ambient factory lighting conditions. Its TTL-compatible serial interface simplifies integration with 5V microcontrollers such as PIC or AVR devices, enabling compact status displays for energy meters, flow controllers, and process monitoring panels. The DIP package format supports hand-soldering and socketed installation, making it appropriate for low-to-medium volume industrial production and field-replaceable display assemblies.

Frequently Asked Questions
What character height and LED color does the HCMS-2902 provide for industrial display applications?
The HCMS-2902 features a 3.71 mm character display height using high-efficiency red LEDs, providing readable alphanumeric characters visible from over 1 meter in typical indoor industrial environments with ambient lighting, suitable for equipment status panels and instrumentation displays.
What is the maximum forward voltage of the HCMS-2902 and how does it affect power supply design?
The HCMS-2902 has a maximum forward voltage of 5.5 V, allowing direct connection to a 5V supply rail in TTL-compatible systems without requiring a separate display power supply, simplifying the overall design and reducing BOM cost in industrial controllers and panel meters.
How does the serial input interface of the HCMS-2902 reduce microcontroller I/O pin requirements?
The HCMS-2902 uses a serial shift-register input interface that requires only 3 to 4 signal lines (clock, data, load, and enable) regardless of the number of display digits, compared to parallel-interface displays that may require 8 or more I/O pins per digit for direct segment drive.
What package type does the HCMS-2902 use and how does this affect PCB design choices?
The HCMS-2902 uses a dual-in-line (DIP) through-hole package with standard 0.1-inch (2.54 mm) pin spacing, enabling hand-soldering during prototyping, socketed installation for field replacement, and compatibility with standard DIP footprint PCB layouts without specialized SMT paste printing equipment.
In which industries and end-equipment categories is the HCMS-2902 most frequently deployed?
The HCMS-2902 is commonly deployed in industrial process control panels, energy measurement equipment, vending machines, retail point-of-sale terminals, and laboratory instruments where a compact 3.71 mm red alphanumeric display at 5V TTL logic provides a cost-effective human-readable output without requiring graphical display controllers.
