The Optek OPI1264C is a single‑channel, through‑hole optically‑coupled isolator designed to transmit electronic signals between circuits while maintaining galvanic separation. Featuring an infrared LED input (≈ 890 nm) and an NPN phototransistor output, it supports a high isolation voltage of up to 10 kV DC, making it ideal for industrial, medical, and office equipment needing safe signal transfer across different supply domains. The device comes in a 4‑pin axial/through‑hole package and is RoHS-compliant, offering a reliable, low‑cost solution for signal isolation in demanding environments.
The OPI1264C is engineered for environments where noise‑free, isolated signal transfer is essential. Its LED‑to‑transistor optical path physically isolates circuits, limiting interference and ground‑loop issues. The high isolation rating supports safe design across segmented voltage domains, while the through‑hole construction offers mechanical robustness and ease of rework.
