Introduction

The 91-21UYC/S530-A3/TR7 is a LED indication discrete device that is used for displaying a variety of applications. It has a range of features, including a wide range of input voltages from 1.8V to 15V and a maximum power output of 35 milliwatts. This device is suitable for a variety of applications, including industrial, automotive, and consumer electronics markets.

Operation and Application Field

The 91-21UYC/S530-A3/TR7 is a high-speed indicator device that provides quick visual feedback to operators and technicians. It supports an output current of up to 30mA and a voltage supply of 1.8V to 15V. This can be used in a variety of applications. In automotive applications, this indicator is used to verify the presence of electric power (12V), or it can be used to detect a fault such as an open circuit. In consumer electronics, this device is used to indicate the status of a device, such as power, battery, or fan. It is also used to alert the user to an alarm or message.The 91-21UYC/S530-A3/TR7 also has the ability to provide inverted or periodic blinking of the output signal, which makes it suitable for applications that require a visual attention-grabbing effect. This call-to-action can be used for a variety of functions, including alerting the user to an out-of-condition state or activating a preset mode.The operation of the 91-21UYC/S530-A3/TR7 is based on a phototransistor configuration. It uses a forward-biased LED acting as a light source and a phototransistor, which is a transistor with a sensitive base-emitter junction, to detect light. When the LED is activated, the change in light intensity sends a signal to the phototransistor, which changes its resistance. This change in resistance is then fed to the load, enabling it to detect and respond to the LED’s activation.

Conclusion

The 91-21UYC/S530-A3/TR7 is a high-speed indicator device with a wide range of uses. Its relatively low voltage and power requirements make it suitable for a variety of applications, such as automotive, industrial, and consumer electronics markets. This device supports an output current of up to 30mA and a voltage supply of 1.8V to 15V, enabling it to be used in a variety of applications. It also offers inverted or periodic blinking output, making it suitable for applications requiring visual attention-grabbing effects. Finally, this indicator is based on a phototransistor configuration, enabling it to detect light and transmit the resulting signal.
