The 1SNA645550R1100 is an OBROC2000-5-12VDC optocoupler featuring an R600 solid-state output module with spring terminals for reliable electrical isolation. It accepts a 5-12VDC control supply voltage (A1-A2) and provides a solid-state output capable of switching 4.5 to 58VDC at currents from 1mA to 2A, making it suitable for industrial control and switching applications. The device is housed in a compact boxed form with dimensions of 75mm length × 67.5mm height × 6mm width, weighing 0.02kg. Its MOS-FET output technology ensures fast switching response and low power dissipation, while spring terminal connections provide secure and maintenance-free installation. This optocoupler is widely used in automation systems, motor control circuits, and industrial relay replacement applications where galvanic isolation and high current switching capability are required.
