Durable HENGTUO HT-817-B-F Photoelectric Coupler with Wide Lead Spacing and RoHS Compliance

Product Overview

The HT-817X is a photoelectric coupler designed for efficient light-to-electrical signal conversion. It comprises a light-emitting diode and a phototransistor, available in a 4-pin package with wide-lead spacing and SMD options. Key features include a high current transfer ratio (CTR MIN. 50%), superior input-output isolation voltage (Viso = 5,000Vrms), and a broad operating temperature range of -55 to 110. This robust performance makes it suitable for applications in programmable controllers, switching power supplies, intelligent meters, and various home appliances like air conditioners, fans, and water heaters. The product adheres to stringent safety approvals and RoHS compliance.
