Durable Photoelectric Coupler HENGTUO HT-3H4-ATP1 with RoHS Compliance and Multiple Safety Approvals
Product Overview
The HT-3H4X is a photoelectric coupler designed with two light-emitting diodes and a phototransistor, housed in a 4-pin package. It offers wide-lead spacing and an SMD option. Key features include a current transfer ratio (CTR) of a minimum 20% at IF = 1mA, VCE = 5V, and high input-output isolation voltage (Viso = 3,750Vrms). The device operates within a temperature range of -55 to 110 and holds multiple safety approvals including UL 1577, VDE DIN EN60747-5-5, and CQC11-471543-2022. It is also RoHS compliant and rated MSL1. Applications include programmable controllers, switching power supplies, intelligent meters, and home appliances such as air conditioners, fans, and water heaters.
