The 1SNA645005R0700 is a boxed interface relay (R600 series) designed for industrial control applications requiring reliable switching of AC loads. It features a single SPDT (changeover) contact with gold-plated surfaces rated for 5–250 VAC at 10 mA up to 6 A, controlled by a 24 VAC/DC rated supply voltage applied to coil terminals A1–A2. The relay includes an integrated LED indicator for visual status confirmation and employs screw terminals for secure wiring connections. This compact relay (6 mm width, 67.5 mm height, 70 mm depth) is suitable for panel-mount applications in automation, HVAC systems, and general industrial control circuits where space efficiency and reliable contact switching are required.
