Overview
The Everlight IRM-3638T is a compact infrared LED module designed for high-efficiency signal transmission in remote control and sensing applications. Manufactured by Everlight Electronics, a leading global supplier of optoelectronic components, this module is widely recognized for its durability and consistent performance. With a peak wavelength of 940 nm, the IRM-3638T is optimized for use in consumer electronics, industrial automation, and security systems. Its small form factor and robust construction make it suitable for integration into space-constrained designs while maintaining high reliability.
Structure and Working Principle
The IRM-3638T consists of a GaAs-based infrared LED chip housed in a molded epoxy package. The chip emits infrared light when an electric current passes through it, with the epoxy lens shaping the beam for optimal transmission. This module operates on a forward voltage of approximately 1.2V to 1.5V, with a typical forward current of 20mA. The emitted infrared light is invisible to the human eye but can be detected by specialized sensors, making it ideal for remote control and proximity detection applications.
Key Features
The IRM-3638T offers several notable features, including high radiant intensity (typically 20mW/sr at 100mA) and a narrow beam angle for precise signal targeting. Its low power consumption makes it energy-efficient, while its epoxy encapsulation ensures resistance to environmental factors like humidity and dust. Additionally, the module's compact design (3mm x 2mm x 1.8mm) allows for easy integration into various electronic devices. Its RoHS compliance ensures it meets global environmental standards, making it suitable for use in eco-conscious applications.
Application Areas
This infrared LED module is commonly used in TV and air conditioner remote controls, where reliable signal transmission is crucial. It also finds applications in industrial automation for object detection and counting systems. In the security sector, the IRM-3638T is employed in motion sensors and surveillance equipment. Its consistent performance makes it a preferred choice for automotive applications like in-car entertainment system controls and night vision assistance.
Maintenance and Precautions
To ensure optimal performance and longevity, avoid exceeding the maximum forward current (typically 100mA) and reverse voltage (5V). Proper heat dissipation should be maintained during operation, especially in high-duty-cycle applications. When soldering, keep the temperature below 260°C and limit the soldering time to prevent damage to the epoxy package. Storage should be in a dry environment at temperatures between -40°C to +85°C to maintain component integrity.
B2B Procurement Guide
When procuring the IRM-3638T in bulk, verify the manufacturer's authenticity through authorized distributors to avoid counterfeit products. Consider minimum order quantities (MOQs) which typically range from 1,000 to 10,000 units for competitive pricing. Lead times generally vary from 4 to 8 weeks depending on order volume. For custom requirements (such as specific binning or packaging), discuss options with suppliers in advance. Quality certifications like ISO 9001 should be confirmed when evaluating potential suppliers.
