The IN-S121AS5B is a solid state indicator designed specifically for the LED indication in discrete applications. It is an ideal choice for limited space applications and can be used in a variety of industrial, military and commercial applications.The IN-S121AS5B is a single-color, red, 5mm LED module. It has an operating current of 20mA and is designed with a “push on, push off” momentary switch. The module measures 20mm in length and 9mm in width, making it small enough to fit into most tight spaces. The lenses are constructed from a diffused polycarbonate to provide excellent uniform light intensity and superior brightness.The IN-S121AS5B provides a reliable and straightforward solution for discrete LED indication applications. The module is capable of signaling with either steady or flashing light, depending on the specific application. The internal circuit of the device is designed to ensure that the power of the LED is limited to the specified current and temperature rating, giving the device a long usable life.The working principle of the IN-S121AS5B is based on the basic concept of supplying a constant forward current to the device. This is accomplished by using a series combination of resistors and capacitors connected in parallel to the load. The resistors limit the base current and the capacitors maintain a constant current, allowing the LED to emit steady illumination. When the momentary switch is activated, the capacitors discharge and the LED turns off. When the switch is released, the resistors charge the capacitors, restoring the LED to its original state.The IN-S121AS5B is a reliable and robust device, providing an efficient and cost-effective solution for LED indication applications. Its small size and easy installation process make it an ideal choice for where space and weight saving is a priority. In addition to its main usage as a warning or signaling device, the IN-S121AS5B can also be used in temperature monitoring and sensing applications. Its excellent light intensity and uniformity ensure that it can be used in any environment, from the harshest industrial to the most delicate medical applications.
