LITE-ON Technology
If your design depends on optoelectronics, LITE-ON Technology belongs on your shortlist. It is a manufacturer with core device families that include visible LED products, coupler devices, sensing devices, and infrared components grouped under one optoelectronic semiconductor lineup. That makes it a practical name for buyers who need parts that handle indication, isolation, sensing, and light-based detection.
That range is why LITE-ON Technology matters to engineers, buyers, and repair teams. LITEON lists four product groups: Visible, UV & Automotive LEDs, Couplers, Optical Sensors, and IR Emitters & Detectors. Those groups support real circuit needs across industrial, computing, consumer, and communications applications.
At Summit Electronics, we work as an electronic parts supplier for companies that need current inventory, allocated stock, and obsolete electronic parts. Since our founding in 1961, we have focused on personal service, and today we support buyers with over 2 million parts in stock and a global sourcing network. You can learn more on our About Summit page.
What We Stock From This Manufacturer
LITE-ON builds several optoelectronic component lines that buyers regularly need for new designs, repairs, and replacement sourcing. From indicator and display LEDs to couplers, optical sensors, and infrared devices, these parts support control boards, sensing systems, interface circuits, and other equipment where dependable light-based performance matters.
- LED-related consumer electronics parts
- Couplers and broader product sourcing support
- optical sensors for automation applications
- IR emitters and IR detectors in diode-related sourcing
LITEON’s own product overview places all four of those lines inside its optoelectronic semiconductor portfolio.
LEDs for Indication and Display Work
LEDs remain one of the most common optoelectronic building blocks in modern equipment. They support indicator lamps, status displays, backlighting roles, and other visual output functions inside boards, panels, and assemblies. LITEON includes visible LED devices as a core part of its optoelectronic lineup.
When you are selecting current-limiting parts to support these LEDs, our guide on choosing the correct resistor value for an LED circuit gives you a solid technical starting point.
Couplers for Isolation Circuits
Couplers matter when a design needs electrical isolation and reliable signal transfer between circuit sections. LITEON positions this line around photocouplers built for industrial, computing, consumer, communication, clean energy, and automotive uses.
In practical terms, Couplers help protect control logic while passing information across isolation boundaries. That makes them relevant in power supplies, controllers, interface boards, and service replacements where signal integrity and protection both matter.
Optical Sensors for Detection and Control
Optical sensors help a system detect light, proximity, color, or environmental input without mechanical contact. LITEON describes this product line as part of its intelligent sensing portfolio, with applications in industrial automation, security cameras, biometrics, and consumer devices.
For buyers maintaining automation hardware, optical sensors often sit at the center of detection, feedback, and trigger functions. That makes exact part matching important when uptime and response accuracy matter.
IR emitters and IR detectors for Invisible Light Systems
IR emitters and IR detectors support light-based sensing paths where visible light is not the goal. LITEON highlights this family for industrial automation, consumer products, security cameras, and biometric uses.
In the field, IR emitters work by sending the infrared signal, while IR detectors receive or respond to it. That pairing shows up in interrupters, proximity assemblies, sensing modules, and other circuits where fast, repeatable light response matters.
Why Buyers Source These Parts Through Summit
We are not limited to a narrow catalog page. Our broader product offering covers current, hard-to-find, and legacy inventory, and our team supports buyers across aerospace, defense, robotics, energy, and MRO-driven repair work. Summit also specializes in obsolete electronic parts, which matters when an older assembly still depends on a specific optoelectronic device.
If you are dealing with discontinued stock, long equipment life cycles, or urgent replacement needs, our article on finding discontinued inventory fast explains how we approach those sourcing problems. That same sourcing model helps us support obsolete electronic parts without forcing unnecessary redesigns.
When you need LITE-ON Technology parts, we give you a direct path to pricing, availability, and cross-check support. As your electronic parts supplier, we help you source active inventory, legacy replacements, and obsolete electronic parts with speed and accuracy.
We’ve built our reputation on reliability and speed. That’s why the world’s largest industry MRO’s rely on us. Click here or call us toll-free at (800) 226-6960.
