The QS121XXHR220 is an energy-efficient and IP67 rated panel indicator, pilot light, and indicator light designed for the harshest industrial applications. Its construction features die-cast aluminum housing for the highest protection against moisture or corrosive environments; it can be mounted on panels or machine bodies.

The QS121XXHR220\'s bright and clear LED lighting creates long-lasting visibility in low-light or even no-light conditions. Visual alerts can be used to indicate necessary action, or used to provide positive feedback or guidance. The drive voltage for the QS121XXHR220 is no higher than DC 5V, which eliminates the need for additional power supplies. The pulse intensity of the LED driver effectively reduces the energy consumption, further yielding improved energy efficiency.

The QS121XXHR220 is available in a panel-mount style for direct-mount applications, as well as a single-shaft and double-shaft panel mounting. The single-shaft and double-shaft versions feature specially designed center-pins with widened diameters to ensure secure connections. These features allow the QS121XXHR220 to be quickly and easily installed, with minimal effort.

QS121XXHR220 can be used in a variety of applications and industries, ranging from industrial machinery and factory automation to medical applications and military vehicles. It has become one of the most extensively used panel indicators and pilot lights in the industry, while offering superior visibility and automatic regulation of the LED illumination intensity. The LED’s instant on/off capability eliminates warm-up time, providing a dependable source of energy for even the most critical applications.

The QS121XXHR220 contains a voltage-regulator diode pair that drives the LED, providing a stable power supply that is unaffected by external conditions. This ensures consistent visibility of the LED indicator light, even in cases of voltage spikes, eliminating the need for resetting or adjusting the displays. The voltage-regulator diode pair can also be adjusted to provide a suitable LED color for the specific application.

The QS121XHR220 operates under DC voltage, from 5V to 36V, and its LED intensity automatically adjusts to meet the light levels of any environmental conditions. In addition, the LED indicator and pilot lights have two power-saving modes, dimming and flash mode, allowing them to be synchronized with existing ambient lighting, as well as providing illumination that is visible to speeding vehicles.

The QS121XXHR220 is designed to be a reliable and robust solution to any lighting application. Its durability and IP67 rating makes it suitable for even the most extreme environments, while its wide voltage range and adjustable LED intensity adjustments make it a perfect choice for any application.
