SC10-21SYKWA Application Field and Working Principle

The SC10-21SYKWA display module is part of a family of LED character and numeric modules from Kingbright. It is designed to be used in applications such as barcode scanners, medical instrumentation, industrial automation, audio-visual systems, and vending machines.

The SC10-21SYKWA has an external diameter of 22.5mm with seven segment characters and an illuminated background. It is constructed with a plastic housing and an acrylic lens. It uses an aluminum mould frame and a light-weight plastic substrate.

It features an ultra-thin profile and an IP67 rating, making the unit very resistant to dust and moisture. It also includes a built-in current limiting circuit and a reverse voltage protection function to protect the display and the device it is connected to.

The module operates at 3.2V at 10mA and has an operating temperature range of -20°C to 70°C. It emits a luminous intensity of approximately 175 mcd per segment and has a viewing angle of 120°.

The working principle of the SC10-21SYKWA display module is simple and easy to understand. It is composed of regularly arranged LEDs and resistors, which are connected to an external power source or controller to drive the LEDs. When the controller sends a signal to activate a certain LED, the voltage across the LED increases and it emits light accordingly. This light is then spread outward from the LED and can be seen from a distance. The brightness of the LED can be adjusted by changing the voltage or current signal provided to the LED.

In conclusion, the SC10-21SYKWA display module is a LED character and numeric module that is ideal for use in applications such as barcode scanners, medical instrumentation, industrial automation, audio-visual systems, and vending machines. It features an ultra-thin profile, an IP67 rating, and a luminous intensity of 175 mcd per segment. The module operates at 3.2V and 10mA and has a temperature range of -20°C to 70°C. The working principle of the SC10-21SYKWA is based on LED lights connected to an external power source or controller, which are activated when a signal is sent from the controller.
