Achieve dependable, high-isolation DC signal switching with our industry-standard Phototransistor Output Optocouplers at Al-Hekmh Electronics. These highly versatile optical isolators combine an infrared LED with a silicon phototransistor receiver, blocking hazardous high voltages and ground loop noise from corrupting your low-power control circuitry.
Offering stable current transfer ratios (CTR) and standard switching frequencies, our phototransistor couplers simplify voltage translation and feedback networks. They are the universal choice for switch-mode power supply (SMPS) feedback loops, microcontroller input isolation, industrial PLC interfaces, and general-purpose relay control lines.
