The K1010 series phototransistor photocoupler consists of an infrared emitting diode optically coupled to a phototransistor detector. Available in a 4-pin DIP package with options for wide-lead spacing and SMD, these photocouplers offer high isolation voltage and are Pb-free and RoHS compliant. They are suitable for signal transmission between circuits of different potentials and impedances across various system appliances, instruments, and control systems.
