The LCR-0202 optical coupler from SENBA is a reliable isolation component designed to provide safe signal transmission between electrically isolated circuits. Built with high-performance optoelectronic technology, it ensures efficient signal coupling while maintaining strong electrical isolation, making it ideal for industrial, power, and control applications.
Featuring a DIP-4 package, the LCR-0202 supports an input current range of 0–20mA and operates with an input voltage of 1.6–2.5VDC, enabling compatibility with standard logic and control circuits. With an insulation voltage rating exceeding 2500VRMS, it provides excellent protection against high-voltage transients, improving system safety and reliability. Its working frequency of up to 300kHz ensures fast signal transmission, making it suitable for switching and signal isolation applications.
Designed for stable performance, the LCR-0202 operates within a temperature range of -30°C to +70°C and supports storage up to -40°C to +80°C. Compared to lower-grade optocouplers, it offers improved isolation capability, better noise immunity, and enhanced long-term durability.
Its compact DIP-4 form factor allows easy integration into both prototyping and production-level PCB designs.
