SA1 vs SA3 vs AD16-22DS: How RY-ELE Redefines Industrial Indicator Lights with Innovative Design and Brand Differentiation
What Is an Indicator Light and What Is It Used For?
An indicator light is a small yet crucial component in industrial automation, designed to provide visual feedback about the operational state of electrical equipment or control systems. These lights use color-coded illumination to indicate specific conditions—such as power ON (green), fault (red), standby (yellow), or process running (blue).
They serve as the “communication language” between machines and operators, allowing engineers to quickly assess system status without direct contact with the equipment.
In control panels, production lines, and factory systems, indicator lights help:
-
Enhance operational safety by signaling abnormal conditions.
-
Improve maintenance efficiency by identifying fault locations.
-
Increase automation visibility for smooth system monitoring.
Modern indicator lights, like those designed by RY-ELE, integrate LED technology for higher brightness, lower power consumption, and longer lifespan—making them essential for smart manufacturing environments.
RY-ELE’s Approach: From Standard to Smart
As automation systems evolve, the expectations for control components have grown beyond functionality. Engineers now seek durable, modular, and visually cohesive designs that fit seamlessly into modern industrial panels.
RY-ELE responds to these demands with two complementary product lines:
-
The SA Series (SA1 & SA3) — representing high-end, modular, and innovative design.
-
The AD16-22DS — providing reliable and cost-effective performance for mainstream applications.
This dual product strategy ensures RY-ELE meets both premium automation and general industrial market needs.
SA1 & SA3: The SA Series for High-End Automation
The SA Series embodies RY-ELE's commitment to innovation, flexibility, and industrial aesthetics.
-
SA1 Plug-in Type:
The SA1 uses an advanced cage clamp plug-in wiring system, allowing 1-second, tool-free connection and strong resistance to vibration. It features a modular three-part structure (head, middle base, and micro switch module) that can be freely configured to suit different functions—such as illuminated buttons, selectors, or emergency stops, and also has indicator light type. This makes it ideal for custom-built control panels and OEM automation equipment. -
SA3 Push-in Type:
The SA3 offers a direct push wiring structure, a plastic-edge or metal-edge body, and supports up to 15A high current. It's built for durability and quick installation in demanding industrial settings. With voltage options from 9–24V and high visibility, it delivers both functionality and refined appearance, making it suitable for industrial machinery, smart factory systems, and heavy-duty controls.
Together, the SA Series represents RY-ELE's premium product line—efficient, robust, and visually distinctive.
AD16-22DS: The Reliable Standard for General Industry
The AD16-22DS 22mm indicator light is one of the most recognized models in the industry, offering a balance of performance, durability, and value.
It uses energy-efficient LED illumination and comes in five color options — red, yellow, blue, green, and white — to meet diverse signaling requirements.
With long service life, stable brightness, and universal panel compatibility, the AD16-22DS is trusted in electrical cabinets, control panels, machinery, and factory equipment around the world. It represents RY-ELE's commitment to reliability and practicality in mass-market applications.
RY-ELE's Brand Differentiation
While the AD16-22DS serves as a dependable solution for standard industrial needs, the SA1 and SA3 series position RY-ELE as a leader in innovation and design differentiation.
By integrating modern aesthetics, modular engineering, and user-centered functionality, RY-ELE bridges the gap between traditional electrical components and the demands of next-generation automation.
This tiered product strategy reinforces RY-ELE's brand identity — offering both accessible solutions for everyday use and premium systems for high-performance industries.
